4. ADS1100 Hat with Core2

ADS1100 Hat with Core2

  • B

    Dear all,
    I need a better resolution for a project and I have seen that the internal ADC of the ESP32 is really noisy. So I ordered an ADS1100 for my Core2.
    In the meantime I tried to connect an ADS1100 hat (that I bought for an M5Stick).
    I connected it to the Port A of my Core2

    Here the code:

    from m5stack import *
    from m5stack_ui import *
    from uiflow import *
    import time
    import unit
    screen = M5Screen()
    screen.clean_screen()
    screen.set_screen_bg_color(0xFFFFFF)
    adc_0 = unit.get(unit.ADC, unit.PORTA)
    label0 = M5Label('Text', x=126, y=113, color=0x000, font=FONT_MONT_14, parent=None)
    while not (btnA.isPressed()):
    label0.set_text(str(adc_0.voltage))
    wait_ms(1)

    When I upload I read:
    ADC unit maybe not connect

    Any suggestion?
    Thank you!

  • Hello @brvus76

    according to the schematic the hat needs 3.3 V.

    Thanks
