Hello, I have been working with the FRDM-K64F board with an EVBCRTouch board with MQX/KDS 3.0. It's taken me a while to get it talking, but I think I have the interface working in general. However, I don't see any X/Y data on the status registers. I do see pressure values (I haven't validated them yet). I have manually calibrated the device, but I am not sure if I have everything set correctly. The EVBCRTouch did not come with any bare metal configuration data for the 7" touch panel. Can you provide me proper configuration data for the 7" touch panel that came with the EVBCRTouch? Is there something I'm missing?
I've attached a screen shot of the I2C waveforms:
T = is the start of the trigger, for which I disable the PENEVT interrupt while I'm servicing the request.
A = is the start of the receive data, where I retrieve the status and position data.
B = is the point at which I re-enable the PENEVT and wait for a new ISR.
I'm sampling every 10ms.
