DAC
Example
Output waveforms at pin 25 using the dac0 channel
from m5stack import *
from m5ui import *
from uiflow import *
import machine
import time
setScreenColor(0x222222)
dac0 = machine.DAC(26)
while True:
dac0.write(0)
wait(1)
dac0.write(255)
wait(1)
wait_ms(2)
API
dac0 = machine.DAC([pin])- Setting the conversion channel
dac0.write(255)- Write DAC conversion value
dac0.beep(1800, 200, 0)- Configure the outputs to drive the buzzer frequency, time and amplitude.
dac0.waveform(1800, dac0.SINE, duration=200, scale=0, offset=0, invert=0)- Setting the output waveform frequency amplitude offset
dac0.stopwave()- Stop Output
dac0.freq(1800)- Setting the output frequency
