import unit
screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)
ain420ma_0 = unit.get(unit.AIN_420MA, unit.PORTA)
ain420ma_0.init_i2c_address(0x55)
while True:
print((str('version:') + str((ain420ma_0.get_firmware_status()))))

wait_ms(2)API
ain420ma_0.init_i2c_address(0x55)- Initialization of 4~20mA input unit
print((str('value:') + str((ain420ma_0.get_adc_raw16_value()))))- Obtain ADC raw 16-bit value
print((str('current:') + str((ain420ma_0.get_ain_current_value()))))- Obtain current value (mA)
print((str('version:') + str((ain420ma_0.get_firmware_status()))))- Obtain firmware version number
ain420ma_0.set_i2c_address(0x55)- Set I2C communication address
