ESP8266 Arduino

1 概述

开源项目主页：https://github.com/esp8266/Arduino

2 开发板

设计考虑：

2.1 管脚布局

D0	GPIO3 (U0RX) / URX during flash programming
D1	GPIO1 (U0TX) / SPI_CS1
D2	GPIO2* (U1TX) / UTX during flash programming	
D3	GPIO16

D4	GPIO4  (SDA)
D5	GPIO5  (SCL)

D6	GPIO0*  SPI_CS2
D7	GPIO8 (SD_D1 / SPI_MOSI)
D8	GPIO7 (SD_D0 / SPI MISO)
D9	GPIO6 (SD_CLK / SPI_CLK)

D10	GPIO15* (HSPI_CS)
D11	GPIO13 (HSPI MOSI)
D12	GPIO12 (HSPI MISO)
D13	GPIO14 (HSPI CLK)
	

A0      TOUT
	GPIO9 / SD_D2 ---> Used by flash HOLD-
	GPIO10 / SD_D3 ---> Used by flash WP-
	GPIO11* (SPI_CS0) ---> Used by flash
	EN
	GPIO16
	RST

GPIO2, GPIO0 和 GPIO3 (U0RXD) 用作 GPIO 要留意，外围电路，有可能影响其状态，造成正常启动失败。应避免使用 GPIO0, GPIO2, GPIO15

nodemcu v1.0:

D0	GPIO16
D1	GPIO5	
D2	GPIO4	
D3	GPIO0	
D4	GPIO2  (U1TXD)
D5	GPIO14 (SPI CLK)		
D6	GPIO12 (SPI MISO)		
D7	GPIO13 (SPI MOSI)
D8	GPIO15 (SPI CS)
D9	GPIO3 (UART RX)
D10	GPIO1 (UART TX)
D11	GPIO9
D12	GPIO10
