Sample LL_USB.ini file showing default settings with explanation of optional settings with links to full documentation for each setting Using LL_USB.INI in Win7/8/10 |
|
|
|
When the LL_USB software is installed it places file LL_USB.INI in the Windows folder where most .ini files reside. LL_USB.INI has configuration parameters that are used by LL_USB2K.DLL which is used by the main application LL_USB2K.EXE. The default parameters are fine for most installations and that file never needs edited. There are certain parameters that can be edited to improve performance on a system that has a driver that makes excessive use of the CPU and other system resources preventing our driver from retrieving and delivering it's scan data efficiently. Certain steps are required in Win7 to edit and then save that file to the correct location due to the way it uses a virtual storage place for such purposes. A user's virtual storage or "VirtualStore" as it's known, is located in the following location on the PC: Computer->LocalDisk->User->[username]->AppData->Local->VirtualStore The usual place for .ini files that have been edited and will be used by an application next time the application loads is: VirtualStore->Windows To edit the LL_USB.INI file, copy it to that folder and then open it with Windows Notepad. Once edited it can be saved and the changes will be used next time the application is loaded. For information concerning the contents of that file follow the link at the top of this page or just go directly there by clicking HERE. Each parameter is a clickable hyperlink that will take you to an explanation of how that particular parameter is used by the DLL. Once the LL_USB.INI file is in the VirtualStore->Windows folder the application will no longer use the one within the Computer->LocalDisk->Windows folder. |
LL_USB.INI should be placed in the Windows directory automatically by the Windows installation process. LL_USB.INI contains information used by the DLL for optional debug output as well as various DLL-to-app messaging options. It ships with default values which are the same values used by the DLL if it fails to find LL_USB.INI at runtime. Important note: The application's DLL which reads the LL_USB.INI file will not read it unless it's placed within the Windows directory. |

Default: DebugLvl=0 Example: DebugLvl=2 This entry can be used for troubleshooting issues associated with functionality of DLL and its interraction with the running application and the device driver. By default this value is set to 0. When the value is non-zero, the DLL will create a folder called M30x_DBG. In Win7, that folder will be found in: Computer->LocalDisk->User->[username]->AppData->Local->VirtualStore->Program Files(x86)->LL_USB It will then create a file with a name that is made up of the running application's main window handle and the number of times that the DLL's initialization process has been called. For example, "7B0130_0.txt could be a debug filename. The DLL will then write vaious runtime information to the file. The minumum debug output is 1 and the maximum is 5. It is not recommended that any value greater than 3 be used except under extreme troubleshooting conditions since a very large debug file can be created very quickly especially when the device is in scanning mode. A great deal of information can be obtained by simply setting the value to 2 or 3 and is the setting we usually use at the factory when testing the robustness of the DLL, device driver, and related calling applications. Click here to see an example of a debug file that was created by us at the factory. At the left margin of the file, you'll notice a number, which is then followed by a space and then sometimes another number such as, "6699460 2742:". The first number is the "clock" shown as number of milliseconds that have elapsed since the DLL was loaded, followed by the "Device ID" represented by a hexedecimal value. The "Device ID" is shown in hexidecimal format. To convert it to decimal format which is the number shown on the actual hardware chip, the Windows calculator can be used. |
Default: MsgEnable=0 Example: MsgEnable=1 We no longer recommend setting this entry or the two that follow to anything except zero, but a setting of one is still supported for backward compatibility. When an application makes a call to the DLL's DisableDialog() function, these three entries are ignored by the DLL since they are related only to the type of messages that will be displayed to a Windows Message Box (if any). If this entry is set equal to "0", the resources used by the message box will still be used, but the message box will never be displayed. If this entry is set to 1, the message box will be displayed whenever there are messages available to show to the user but the amount of messages will be controlled by the next two entries that follow. |
Default: MsgLevel=0 Example: MsgLevel=1 This entry and the one that follows are ignored if the previous entry is set equal to zero. Otherwise this entry works with the one that follows to control the amount of messages that are displayed when messaging to the Windows Message Boxes is enabled. This entry, although not currently being used at the time of this documentation, has been and may again be used in the future to control the amount of messaging that will be sent - similar to the functionality of the DebugLvl entry in regard to debug file output. |
Default: MsgType=0 Example: MsgType=1 This entry and the previous one are ignored if the MsgEnable entry is set equal to zero. Otherwise this entry will determine if intense trouble-shooting type messages are displayed or just basic, somewhat informative type messages are displayed. We recommend that this entry be left set to zero except when troubleshooting. It is more effective to use the debug file output options described further up in this documentation for troubleshooting purposes. |
Default: ScanSystemBoostLevel=0 Example: ScanSystemBoostLevel=10 This entry and the one that follows controls functionality of the device driver and its interraction with lower-level drivers that are part of the operating system kernel. This entry is only used during scanning mode. We recommend that you only set this entry to a non-zero value when there is an indication of the data buffer within our device experiencing an "overflow" which results in wrapping of its circular buffer. Such a wrap is the result of our device driver not receiving anough of a time-slice from the kernel in order to keep the device's buffer empty. We recommend that if a "microcode buffer wrap" situation occurs, that you first set the StackedIrpCntOverride (discussed next) to a non-zero value and continue to increase it to its maximum setting of 40 to try to cure the problem, before changing this value to a non-zero (or 1) value. Setting this entry to either 0 or 1 has the same effect. The driver will occassionally lower the boost value based on various conditions that would make the boost impractical and as a result also disrupt the error handling built into the driver. Since an increase in boost translates to a larger packet of data being returned by the low-level driver with each read request, a very high boost factor combined with a very slow scan rate could create a condition in which the low-level driver takes many seconds or even minutes to return with one packet of data. Since our device driver has built in request-return timeouts built in as part of its error handling, a large boost factor will be adjusted in such a way as to create a maximum time per packet request to be 1.5 seconds or less. Likewise if the boost exceeds the maximmum boost, it will be adjusted to the maximum before further adjustments are made as described above. The low-level kernel drivers have the highest time-slicing priority. Using this entry takes advantage of that issue. Setting this entry to a non-zero value has the effect of our driver requesting a larger amount of data be read with each read done by the low-level drivers. The side effect is that more time is required per-read by the DLL and thus the application. For example, when in scanning mode and with this value set to zero (or 1) our USB device will return a minumum of 32 bytes with each read - 30 of which are data (1 point = 3 bytes) - which translates into 10 points of data when doing a non-digital-input type of scan. Setting this entry to 2, doubles that to 20 points nd setting it to 3 triples it to 30 points per read. The rate at which the device scans for data is in no way effected by this setting - only the rate at which the data is returned to the user. To further explain... if you set up to scan at 300Hz with this entry set to 0 or 1, you can read 10 points of data 30 times each second. Likewise, with this entry set to 10 with the same scan rate, you can read 100 points of data 3 times each second. In all the previous mentioned situations, the device reads the analog input 300 times per second and all the digital conversions are returned to the user. We added this entry when we discovered that running the "Pinball" game that ships with WinME and later releases would take time-slicing away from our device driver even though it was running a high priority. However, we also observed that the "Pinball" game didn't have an effect on the "low-level" drivers which continued to get their usual time slice. Other drivers that "hog the system" can also have an effect on the slicing allocated to our driver but none seem to effect the slicing allocated to the low-level USB drivers that ship with the operatings system. |
Default: StackedIrpCntOverride=0 Example: StackedIrpCntOverride=20 This entry, like the previous one, controls functionality of the device driver and its interraction with lower-level drivers that are part of the operating system kernel. This entry is only used during scanning mode. The entry name represents the "Stacked Interrupt Request Packet Count Override". We recommend that you only set this entry to a non-zero value when there is an indication of the data buffer within our device experiencing an "overflow" which results in wrapping of its circular buffer. Such a wrap is the resulst of our device driver not receiving anough of a time-slice from the kernel in order to keeep the device's buffer empty. We recommend setting this entry to a non-zero value before changing the ScanSystemBoostLevel previously discussed. If this entry is non-zero, the DLL will make further adjustments to it based on several scan setup parameters as to create the optimum setting for this value. If left at zero, or if the entry isn't present in the .ini file, the DLL will make no adjustment to the value. The low-level kernel drivers have the highest priority as far as their time-slicing. Using this entry (like the previous one) takes advantage of that issue. Setting this entry to a non-zero value has the effect of our driver requesting more "packets of data" with each request, while the previous entry results in a request for "larger packets) with each request. The advantage that this has, is it keeps a constant stack of requests backed up for the low-level driver to read while our driver is processing and sending back to the DLL the data that has already been read. The low-level drivers return each packet to our driver as it is read before it begins to fill the request for the next packet that is waiting on its stack. Fortunately, this process has little or no adverse effects on the higher-level processes other than it can require more memory in a quantity proportional to the number of stacked requests. |
Default: ProcessPriorityBoost=0 Example: ProcessPriorityBoost=1 This entry is seen by the DLL as an indicator to increase its system priority level. The effect that such an increase has is it gives the DLL and the application that is making use of the DLL a very high priority level. This, when used with appropriate settings of the other options within this file can help eliminate issues in regard to DLL and microcode data buffer wraps as described further down. Windows manages many tasks at the same time by giving a slice of time to each of the applications and processes that are running at any given time. Typically, each process is given an equal slice of the time. However, some applications have time critical issues that have to be dealt with and sometimes when a lot of applications are running, the slice that they receive just isn't enough to accomplish what needs to be accomplised within a given frame of time. Applications that use our DLL, especially when scanning for data a high rates can encounter such a defecit of time slicing. Setting this value to "1" will cause the DLL make a request to the operating system to increase its time-slicing by a factor of 4. In other words, it will now get four times as much of a slice as it would ordinarily have. Increasing the priority level can help prevent buffer wraps in a number of ways. There are two main buffers used when using a scanning type mode. One is at the application level and resides in a special memory space that is available to both the DLL and device driver. That memory space is very similar to the virtual disk space used as extra storage for system memory activity. As the device driver reads data from the device, it writes the data into that memory and it is then up to the DLL to read the data from it in order to keep it from filling and overflowing. If many applications are running in the background, the time slice that the application/DLL have to read the data isn't enough and the buffer can overflow. This is ofter reported to the application by way of the DLL and also to the debug file (if one is utilized) also by the DLL as a "Scan Buffer Wrap". Likewise, a wrapping of the device's buffer can also occur if the device driver doesn't call it frequently enough to keep its buffer from overflowing. Since the device driver has such a high prirority (much more than any application) the device driver is usually only affected indirectly by a background application that has a high priority level and at the same time is interracting with its own device driver which may have a higher priority level than our own device driver. Such a situation can be less obvious since any application can indirectly make use of a kernel driver just by making a lot of memory hits that make use of a kernel driver that then uses the hard disk to cache some of that memory out to virtual memory. //******************************************************************* //******************************************************************* // Below is more information about this setting //******************************************************************* //******************************************************************* // FOR WIN98/ME // Valid values are: // 0 = default is used // 1 = high (HIGH_PRIORITY_CLASS) // FOR WIN2k/XP // 0 = NORMAL_PRIORITY_CLASS; // 1 = HIGH_PRIORITY_CLASS; // 240 (0xF0 hex) = IDLE_PRIORITY_CLASS; // 241 (0xF1 hex) = REALTIME_PRIORITY_CLASS; //******************************************************************* //******************************************************************* //FIRST TWO ARE RECOMMENDED AND AVAILABLE IN Win98/ME/2k/XP //3rd and 4th availabe only in Win2k/XP //4th and 5th documented by microsft, but not available at this time. //******************************************************************* //******************************************************************* //NORMAL_PRIORITY_CLASS -> Process with no special scheduling needs. //HIGH_PRIORITY_CLASS-> Process that performs time-critical tasks that must be // executed immediately.
