The Fabulous Logic Analyzer – Problems during port initialization
Wednesday, February 10, 2010 21:02
“TFLA-01 is a simple logic analyzer for the PC. This one consists of a simple schematic which is attached on the PCs parallel port (a real parallel port is highly recommended, not a USB adapter) and which can analyse H and L levels of 8 inputs. On the PC, there’s running a graphical program which displays the contents.”
You can get the schematics and read more about it on tfla-01.berlios.de
There is a chance that you might get into problems with the parallel port initialization. The error message might look like: “An error occurred while colecting data: There was a problem during port initialization. This could be because another driver has opened the port exclusively, or other reason.”
There is a solution to this and it’s name is giveio.sys
- Download the giveio-driver.zip file and extract it on your hard drive.
- Next you need to compile the loaddrv.h, loaddrv.c to get a loaddrv.exe executable.
- Place the giveio.sys file into the same directory as loaddrv.exe
- In the command line type loaddrv.exe install giveio
- Next type loaddrv.exe start giveio
- Run TFLA.exe and enjoy it ;)
