annotate Small_CPU/Src/stm32f4xx_hal_msp_v3.c @ 554:3328189786e7
Added external ADC interface functionality (MCP3424):
Added communication protocoll to read data from external ADC. At the moment 16bit and 18bit resolutions are supported. External data will be read and forwarded depending on the conversion time of the ADC.
