运行下面的代码,会有问题

没发现和视频里的原代码有差别,但如果发送“123456”,得到数据不是一整行打印出来的,如果发送“123456\r\n”的话会报错
# Select an area in the Framebuffer to copy the color settings. import time from machine import I2C #from vl53l1x import VL53L1X from pid import PID from pyb import UART import math clock = time.clock() # Tracks FPS. # For color tracking to work really well you should ideally be in a very, very, # very, controlled enviroment where the lighting is constant... ''' i2c = I2C(2) distance = VL53L1X(i2c) ''' x_pid = PID(p=0.5, i=1, imax=100) d_pid = PID(p=0.05, i=0.1, imax=50) uart1=UART(3,115200,timeout_char=1000) #uart2=UART(3, 115200) #uart2.init(115200, bits=8, parity=None, stop=1) while(True): # clock.tick() # Track elapsed milliseconds between snapshots(). if uart1.any(): x_error=uart1.readline().decode().strip() print(x_error)

用一下这个代码
import time from pyb import UART # Always pass UART 3 for the UART number for your OpenMV Cam. # The second argument is the UART baud rate. For a more advanced UART control # example see the BLE-Shield driver. uart = UART(3, 19200,timeout=1000) while(True): if uart.any(): print(uart.readline())
