Del_Sigma ADC conversion of 1Khz signal in PSOC5lp

Anonymous · ‎Aug 04, 2016

How can i use Del_sigma ADC (differential mode)to sample and convert sine wave signal of 1Khz ? And then i have to send the conversion result through UART to PC. I tried doing so but i get some random symbols. How to overcome this? Resolotion of ADC is 8 bit and conversion rate is 8000sps. UART at 115200bps.

Thank you

The asterisk in "%d*" format requires an additional parameter, I would suggest to delete the "*".

Increase the heap size to 0x200 (in .cydwr view -> System -> Heap size

Your temp-variable is quite too short and sprinf() will overwrite some sram. I suggest to increase it generously to temp[20].

Happy coding

Bob
