Captivate team,
I designed (mostly copied!) a 16 button mutual capacitance board (4 x 4) based on the 64 button TIDA ref design. I had the PCB made and am now testing. When I generate my 16 button project with the Captivate Design Center and load it on the EVM (connected to 16 button board), I see no signal on the TX pins when probing with a scope. I also see no signal on the RX pins.
When I load the EVM with the 64 button project, I see an oscillating digital signal on the TX pins.
I assume there must be something I am doing differently in my Captivate Design Center project, but I can’t find the difference. I compared the captivate_config files and the captivate_app files. The only differences I can find are in captivate_config. Should I be looking at some other files in the project?
Any other suggestions?
Thanks,
Darren
