Pulling an ADC value and using it - Raudert - Feb-07-2017 Hello, I am typing this from a cellphone so please bear with me. But my issue here is I am trying to read an ADC voltage value using an ADS1x15 ADC converter and then store the values as a variable in order to plug that value into an equation. An example script can be seen below: ADC_Value = adc.read_adc_difference(0, gain=GAIN) x_Input = (ADC_Value - 68)*(3/24432) print(ADC_Value) print(x_Input) I am unsure as to what Im missing. I do not get any syntax errors only a value of 0 for my x_Input variable every time it prints. I am working on making a PLC to control an industrial fan and this is my first exposure to programming so please have mercy. Thank you, The Hopeful Noob RE: Pulling an ADC value and using it - mcmxl22 - Feb-07-2017 To help you we need more of the code. We need the code for adc()in adc.read_adc_difference(). RE: Pulling an ADC value and using it - ichabod801 - Feb-07-2017 What version of Python are you using? If you're using 2.x, you need to change one of the values in your division to a float (add '.0' on the end). RE: Pulling an ADC value and using it - Raudert - Feb-07-2017 That was it. How embarassing haha |
