TSC2013EVM: EVM control software

Hello Aaron,

Thank you for your prompt support.

I have forwarded EVM's  FW to our customer and we got their measurement result as below.

X,Y drive waveform looks good, but still read out value is always around 0x02 5E 01 8A, this value is not changed very much.

Do you have any suggestion for next step of debugging?

Regards,

Hello Mochizuki,

I am a little confused by the problem now. Is the problem still an I2C issue or is it now the X and Y measurements?

Regards,

Aaron

Hi Aaron,

It is X-Y measurement value issue, I2C looks working fine now but ADC readout value is not correctly respond.

It is always almost same value outputted.

Do you have any advice to check out the registor setting?

Hello Mochizuki,

Has the touch screen been calibrated? If not, I would look into this. The following App Note provides some useful information on how to calibrate your touch screen controller. 

Also, what is the size of the screen being used?

Regards,

Aaron
