Download Software for the Assembled Gertboard.
I am running into issues with the basic tests for the buttons and leds... For the button test, nothing seems to happen.. The wiring diagram for the button test appears to be correct, and I added the jumpers for outputs B1 - B3 on the pins above U3... With this configuration I would expect leds D1 - D3 to light up when I press one of the buttons, but nothing happens. I also have a jumper on pins 1&2 of J7 so things should be Ok....
When I run the led test I am only using 7 wires for (J3) B1- B7 going to GP25, GP24, GP23.. I connected jumpers for B1 - B7 on U3 & U4... when I have the J7 jumper in place on pins 1&2 nothing happens. When I remove the J7 Jumper all of the LEDs flash through the patterns... The fact that the board flashes without the J7 jumper implies that the board itself is OK.... I've had the Gertboard attached directly to my Pi and I've also tried it via the PiFace rack, thinking that the board is not connected properly when directly on the Pi GPIO connector - I have a RaspberryPi model B and the board seems to not go into place fully due to the USB riser.. I've tried both the C code and the Python code with the same results.
As an aside, when running these tests, CPU on the Pi goes to 100% - no doubt due to the tight loop that the code runs in
