Unit HBridge

Example

Set motor parameters and control motor rotation

from m5stack import *
from m5ui import *
from uiflow import *
import unit

setScreenColor(0x222222)
hbridge_0 = unit.get(unit.HBRIDGE, unit.PORTA)

hbridge_0.init_i2c_address(0x20)
hbridge_0.set_8bit_pwm(127)
hbridge_0.set_16bit_pwm(32767)
hbridge_0.set_direction(1)
while True:
  print((str('Current:') + str(((str((hbridge_0.get_vin_current())) + str('A'))))))
  wait(1)
  wait_ms(2) 

API

hbridge_0.init_i2c_address(0x20)

Initializes Unit and sets the I2C address

print(hbridge_0.get_adc_value(0, 8)) 

Get voltage resolution

print(hbridge_0.get_vin_current())

Get voltage (A, Float)

print(hbridge_0.get_device_status(0xFE))

Get the Unit version

print(hbridge_0.get_driver_config(4))

Obtain configuration information
