HydraFW ADC guide

#HydraFW ADC (Analog to Digital Converter)

Input: 0 to 3.3V
Resolution: 12bits

This guide is updated towards firmware release HydraFW v0.5 Beta: HydraFW (HydraBus) v0.5-beta-0-gc0bc1f0 2015-02-11

##ADC configuration syntax description:

• Usage: adc <adc1/tempsensor/vrefint/vbat> [period (nb ms)] [samples (nb sample)/continuous]
• adc1 is mapped on PA1 pin
• tempsensor Temperature sensor is mapped internally in MCU
• vrefint Internal reference voltage is mapped internally in MCU
• vbat VBAT voltage is mapped internally in MCU

Syntax:

• adc1, tempsensor, vrefint or vbat to choose one or more ADC device

  • Return value in Volt

• sample Number of samples to read

• continuous Read continuously
