Hi All,
We are trying to use this evaluation board with it associated GUI (TRF3761 Programmer). This board and GUI use the parallel port (LPT1). Our PCs do not have parallel ports so we purchased PCI parallel port cards. We set the port to be LPT1 and set the LPT1 base address according to what is listed in the device manager. In this case to first base address listed is 0xE020.
According to the schematic there is an LED that will indicate parallel port activity. We cannot get the board to respond, there is no LED blinkage.
The GUI hangs and crashes often.
Has anyone been able to get this board to function?
Thanks
Rich
Rich,
I apologize for some reason I was not copied on this when it was sent out originally.
I just wanted to follow up and see if you have gotten this board to work yet?
Anything I can help with? What version of Windows are you using? The TRF3761EVM requires WindowsXP
Chris
Chris,
Thank you very much for the reply. No we have not been able to get this to work yet. We are using a WINXP machine. We had to buy a LPT port card as the machine did not originally have one.
Hey Rich,
We have used this board often on computers that come with printer ports and have not had much trouble.
I don’t believe we have tried to purchase a LPT port card and install and then run it. What LPT port card do you have?
A couple questions to help me understand your setup
1. What TRF3761EVM version do you have? The one I have in my office has ‘TRF376X REVE’ on the silkscreen.
2. When 5V is applied to the J13 connector, do LEDs D1 and D3 light up (green LEDs)?
- If not, is the jumper W5 installed?
3. If the 2 LEDs do light up, do the following
- connect the LPT connect
- open the TRF3761 GUI
- In the ‘Top Level App’ section – toggle the chip enable button so that it turns from light green to a dark green color. Wait 1second. When you do this does the D1 LED turn off?
- toggle the chip enable button again so that it is light green, the D1 LED should turn on again
