# DAC Control Example # # This example shows how to use the DAC pin output onboard your OpenMV Cam. import time from pyb import DAC dac = DAC("P6") # Must always be "P6". while(True): # The DAC has 8-12 bits of resolution (default 8-bits). for i in range(256): dac.write(i) time.sleep_ms(20) for i in range(256): dac.write(255-i) time.sleep_ms(20)
