This guide is updated towards firmware release HydraFW v0.9 Beta and later

Output: 0 to 3.3V
Resolution: 12bits

• Usage: dac <dac1/dac2> <raw (0 to 4095)/volt (0 to 3.3V)/triangle/noise> [exit]
• DAC1 is mapped on PA4 pin (used by ULED)
• DAC2 is mapped on PA5 pin

Syntax:

• dac1 or dac2 to choose DAC1 or DAC2 device

• Choose one of the following output type:

  • raw Raw value <0 to 4095>

    • Output real value in decimal and volt

  • volt Volt <0 to 3.3v>

    • Output real value in decimal and volt

  • triangle Triangle output (5Hz and amplitude 3.3V)

  • noise Noise output (amplitude 3.3V)

• exit Exit DAC mode (reinit DAC1&2 pins to safe mode/in)
