使用DFU方式下载

参考下载说明：梁山派使用DFU下载说明
open打开LCKFB_LSPI_MicroPython_V0.1.hex所在目录

注意：DFU下载时候把数据连接到了梁山派开发板板载USB上，测试的时候需要把数据线连接到DAPlink，因为我们是通过串口进行通讯

测试

首先输入help()让我们来看一下micropython简单使用，这里找到点灯的方法

点亮与关闭led1

//tab键可以补全
>>> import pyb
>>> pyb.LED(1).on()
>>> pyb.LED(1).off()

串口输出

>>> print("abcde")
abcde

GPIO控制LED1

>>> from pyb import Pin
>>> myled = Pin("E3",Pin.OUT_PP)
>>> myled.value(1)
>>> myled.value(0)

GPIO控制LED1闪烁

>>> from pyb import Pin
>>> myled = Pin("E3",Pin.OUT_PP)
>>> while True:
... myled.value(1)
... pyb.delay(1000)
... myled.value(0)
... pyb.delay(1000)
