案例程序

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)

功能说明

hbridge_0.init_i2c_address(0x20)

• 初始化Unit并设置I2C地址

print(hbridge_0.get_adc_value(0, 8))

• 获得电压值分辨率

print(hbridge_0.get_vin_current())

• 获取电压（A，Float）

print(hbridge_0.get_device_status(0xFE))

• 获取Unit 版本

print(hbridge_0.get_driver_config(4))

• 获取配置信息
  • DIRECTION
  • 8Bit_PWM_DUTY
  • 16Bit_PWM_DUTY
  • PWM_FREQUENCY

hbridge_0.set_16bit_pwm(32767)

• 设置16bit 值 PWM 占空比

hbridge_0.set_8bit_pwm(127)

• 设置8bit 值 PWM 占空比

hbridge_0.set_direction(0)

• 设置电流方向
• STOP
• FORWARD
• REVERSE

hbridge_0.set_pwm_freq(1000)

• 设置PWM频率
