Micropython学习笔记--Python语言实现串口读写
前文提到,HaaS Python轻应用是对Micropython的深度定制和扩展,本节开始,将详细介绍基于HaaS Python轻应用如何完成串口数据读写
运行的硬件环境: HaaS100开发板,HaaS EDK K1等
# coding=utf-8 # This is a sample Python script. import utime from driver import UART print("-------------------uart test--------------------") print("-----How to test: connect PIN10 and PIN12-------") uart = UART(); uart.open("serial2") utime.sleep_ms(1000) writeBuf = bytearray([0x41, 0x42, 0x43, 0x44]); for i in range(10): uart.write(writeBuf) utime.sleep_ms(1000) readBuf = bytearray(4) recvSize = uart.read(readBuf) utime.sleep_ms(100) print(recvSize) print(readBuf) uart.close()
