dac_base

This example is used to demo the usage of DAC

It is a 10-bits DAC

Log

Use serial port with baudrate 115200, 8bit, no parity check.

• DAC0

  • Measure DAC outupt (PA8)

    • step= 0, PA8 Output= 1 mV
    • step= 128, PA8 Output= 407 mV
    • step= 256, PA8 Output= 815 mV
    • step= 384, PA8 Output= 1219 mV
    • step= 512, PA8 Output= 1627 mV
    • step= 640, PA8 Output= 2017 mV
    • step= 768, PA8 Output= 2413 mV
    • step= 896, PA8 Output= 2825 mV
    • step= 1023, PA8 Output= 3231 mV

      DAC step= 256, Expect Output= 825 mV
      DAC step= 384, Expect Output= 1237 mV
      DAC step= 512, Expect Output= 1650 mV
      DAC step= 640, Expect Output= 2062 mV
      DAC step= 768, Expect Output= 2475 mV
      DAC step= 896, Expect Output= 2887 mV
