CY8CKIT-001 PSoC 3 Delta Sigma ADC
I'm new here and new to cypress. I have measured the variable resistor on board with the multimeter and find that it ranges from 0.27V to 3.23V. And when i connect the variable resistor to the Delta Sigma ADC and print it on the LCD, it print out the digital value in Hex. I tried using a formula, to get back the input analog value for checking in this form, ADCResult/Total ADC bits resolution * max input voltage. I convert the ADC Hex value output into a int variable to do the calculation and realize i do not get back the same value as the analog input. Also i observe that the output of the ADC printed on the LCD does not seem to scale with the variable resistor when i was turning it. Can anyone tell me what's wrong?
