Detailed Description

I2C Analog-to-Digital Converter control and calibration commands.

These I2C commands control ADC operation including:

  • Channel configuration (CMD_ADC_CH_*)
  • PGA (Programmable Gain Amplifier) settings
  • Calibration procedures
  • Filter configuration
  • Sample rate control
  • Voltage/current specific calibration

Commands span ranges 0x016x (channel config), 0x021x-0x023x (USB ADC), 0x025x (USB sweep).
