Nodemcu开发之Win IDE

导读：之前买的新板子，无法直接刷程序，直接在win下又做了一次固件刷写，其实和之前mac上写的写法类似，都很简单

一共有两个比较好用，其中一个是

ESPlorer

https://esp8266.ru/esplorer/

1. win10自带了串口驱动usb2uart，很赞
2. 环境搭建

下载最新的jdk9和ESPlorer有冲突， 无法点击open连接， 这里有讨论，下载jdk8可以解决
https://github.com/4refr0nt/ESPlorer/issues/63
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

3. 软件连接
   选择ide下的com口，在设备管理器的串口中找到usb to uart这个对应的com口号， 在右上角选择对应的端口
   选择对应的频率，点击open，可反复试，通过我之前的文章可以手动刷固件同时给mcu改通信频率

4.刷固件
同mac版文章类似

不同点：

• 下载对应win的python环境 https://www.python.org/downloads/
• win下获取端口dos下使用chgport获取串口名

笔者列表， 如果你不确定是哪个端口，插拔你的nodemcu，端口列表会有增删
C:\Users\admin>chgport
AUX = \DosDevices\COM1
COM1 = \Device\Serial0
COM3 = \Device\Silabser0

• 安装esptool.py是全局环境了，不需要mac那样前面加路径
• 格式化nodemcu

esptool.py --port COM3 erase_flash
esptool.py v2.0.1

• 获取nodemcu容量

esptool.py --port COM3 flash_id

• 刷固件， 因为笔者去年做过固件，所以直接拿了以前的固件来做，你可以到官网上去制作

esptool.py --port COM3 write_flash -fm dio 0x00000 "./package/nodemcu-master-23-modules-2017-07-11-06-57-55-float.bin"

• 好久不碰NodeMcu了，试试最简单的板子上led灯发光的小程序

LED_PIN = 0
US_TO_MS = 1000
gpio.mode(LED_PIN, gpio.OUTPUT)

while true do
   gpio.write(LED_PIN, gpio.HIGH)
   tmr.delay(500 * US_TO_MS)
   gpio.write(LED_PIN, gpio.LOW)
   tmr.delay(500 * US_TO_MS)
end
