openmv h7 plus 实例里面的代码 驱动舵机是出现问题

买了舵机拓展板,没有焊接就是直接插上去。
这是main中编的代码Servo Shield Example.
This example demonstrates the servo shield. Please follow these steps:
1. Connect a servo to any PWM output.
2. Connect a 3.7v battery (or 5V source) to VIN and GND.
3. Copy pca9685.py and servo.py to OpenMV and reset it.
4. Connect and run this script in the IDE.
import time
from servo import Servos
from machine import I2C, Pini2c = I2C(sda=Pin('P5'), scl=Pin('P4'))
servo = Servos(i2c, address=0x40, freq=50, min_us=500, max_us=2500, degrees=180)while True:
servo.position(0, 0)
time.sleep_ms(500)
servo.position(0, 180)
time.sleep_ms(500)

OpenMV的插针肯定要焊接的,没焊接用不了。https://singtown.com/learn/50057/
