串口通信

import sensor, image, time,struct,pyb
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)
clock = time.clock()
led=pyb.LED(1)
led.on()
time.sleep(500)
led.off()
time.sleep(500)
led.on()
uart = pyb.UART(3, 115200)
uart.init(115200, bits=8, parity=None, stop=1)
def send_data_packet(x, y):
	temp = struct.pack("<bbii",
				   0xAA,
				   0xAE,
				   int(x),
				   int(y))
	uart.write(temp)
while(True):
	clock.tick()
	img = sensor.snapshot()
	print(clock.fps())
	send_data_packet(0x12,0x13)
	uart.write('hello world'+'\r\n')
	print('hello world'+'\r\n')

为什么我这样想试试串口，串口助手收不到数据

我只用了一根数据线连接openmv跟电脑

看教程操作，需要TTL转串口模块，或者OpenMV串口调试扩展板。
