AdcAdjust is a tool for evaluating ADC performance of various MCUs. Measurement noise is reduced by averaging. Two methods are provided for fixing measurement offset errors. One, It is best to have a reliable DVM to measure the input test voltage. Two, without a DVM, a LM35 sensor and a thermometer can provide a known input voltage. Then a sofware parameter can fix the error.
PlatformIO enables various MCUs to share the same code package.
Source code is formatted with Doxygen markup. Doxygen is a very good tool for tracing code and linking embedded images.
