大佬们 请问要怎么通过uart串口向主板发送浮点型数据

[kidswong999]

import time
from pyb import UART
import struct
# 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)

while(True):
    p = 3.1415
    uart.write(struct.pack('<f', p))#发送小端，float,4字节
    uart.write(struct.pack('<d', p))#发送小端，double,8字节
    time.sleep_ms(1000)
