        Hello I am using the ADCINC (first chooseable in PSOC designer) and the LCD together. I can get each of them to work, also with the same settings in the global resources. But only 1 can be turned on in main, else it wont work. I use the CY8C29466-24PXI from the cheap developers kit. My guess is that I have some issues with the speed, cause ADC is slow, but what can I do? Can I make LCD and some other ADC work? Can I give em other speeds? Thanks in advance

 Good to hear that.

   

I would suggest to check if some cold joint or bad contact. Also check if possible a endless software loop.

Some thoughts -

   

 

   

1) Are you using shadow registers on ports where you are doing read modify

   

writes to ? If not you will get unpredictable behaviours in you code.

2) Any floating or high z inputs picking up noise, coupling.....?

   

 

   

3) Any ground bounce in system. Use a DSO and look at each pin with DSO

   

set for pk - pk infinite persistance.
