Does anyone have any example C code using the 'read_voltage() function'
We want to use the ADC Pi to read a varying voltage, send it out as a serial 16/17 bit number and then store it
in the R-Pi's memory as a parallel number.
Any examples of C code to do this would be greatly appreciated.
Regards,
Wayne

Hello Wayne
You can find a demo application using the read_voltage() function in our GitHub repository at https://github.com/abelectronicsuk/ABElectronics_C_Libraries/blob/master/ADCPi/demos/demo-adcread.c
read_voltage() takes 5 parameters:
address - I2C address for the target device e.g. 0x68
channel - 1 to 4
bitrate - 12, 14, 16 or 18
pga - 1, 2, 4 or 8
conversionmode - 0 = one-shot conversion, 1 = continuous conversion
The function returns a double-typed voltage from the ADC.
