查看F1C的源代码

=== WiFi ===

ESP8266 接线：

<source lang=bash>
F1C200S			ESP8266Ex				ESP-12F
SPI_MOSI		SDIO_CMD(GPIO 11)		ESP_CS
SPI_MISO		SDIO_DATA_0(GPIO 7)		ESP_MISO
SPI_CLK			SDIO_CLK(GPIO 6)		ESP_CLK
WIFI_RESET(PD16/IO8)	CHOP_PU					ESP_EN(RST)

SPI_CS			SDIO_DATA_3(GPIO 10)	ESP_GPIO10
WiFi_INT(PD18)	SDIO_DATA_1(GPIO 8)		ESP_MOSI

精简 PIN，则：SDIO_DATA_3 (12F_GPIO10, SPI-CS) 拉低、SDIO_DATA_1 (12F_MOSI, WiFi_INT) 悬空
</source>

'''Boot select:'''
* 3V3 <--- ESP8266_GPIO15 (MTDO)
* 3V3 <--- ESP8266_GPIO0
* GND <--- ESP8266_GPIO2

ESP8266 Reset 后，通过判断如下管脚的状态来决定启动模式：  

<pre>
MTDO 	GPIO0 	GPIO2 	Mode 	Description
L 	L 	H 	UART 	串口刷机
L 	H 	H 	Flash 	SPI Flash 正常启动
H 	x 	x 	SDIO 	SD-card 启动
</pre>

MTDO 为 GPIO15

启动时串口输出的 'boot mode:(x, y)' ， x 的低三位对应  {MTDO, GPIO0, GPIO2}
