Re: 我想问一下esp8266怎样转换模式
可以下载 ESP866 管脚请单 看下 strapping 这个 sheet。

这样呢?或者就是在官网的文档那里可以找到我说的文件。

Re: 我想问一下esp8266怎样转换模式
请看下几种启动模式的配置方式。
UART 启动:GPIO15 = 0,GPIO0 = 0,GPIO2 = 1;
SPI 启动:GPIO15 = 0,GPIO0 = 1,GPIO2 = 1;
SDIO 启动:GPIO15 = 1,GPIO0 = 0,GPIO2 = 1。
UART 启动:GPIO15 = 0,GPIO0 = 0,GPIO2 = 1;
SPI 启动:GPIO15 = 0,GPIO0 = 1,GPIO2 = 1;
SDIO 启动:GPIO15 = 1,GPIO0 = 0,GPIO2 = 1。

U0TXD Strapping to chip_test_mode 1: normal mode; 0: chip_test_mode
MTDO Strapping to STRAPPING_GPIO2 for SW boot_sel [2]
GPIO0 Strapping to STRAPPING_GPIO1 for SW boot_sel [1]
GPIO2 Strapping to STRAPPING_GPIO0 for SW boot_sel [0]
SD_DATA3 Strapping to STRAPPING_GPIO[15] for SW sdio_boot_sel [2]
SD_DATA2 Strapping to STRAPPING_GPIO[14] for SW sdio_boot_sel [1]
SD_DATA0 Strapping to STRAPPING_GPIO[13] for SW sdio_boot_sel [0]
Boot_sel SD_sel != 3'b010 SD_sel == 3'b010
7 SDIO HighSpeed V2 IO Uart1 Booting
6 SDIO LowSpeed V1 IO Uart1 Booting
5 SDIO HighSpeed V1 IO Uart1 Booting
4 SDIO LowSpeed V2 IO Uart1 Booting
3 FLASH BOOT
2 Jump Boot
1 UART Boot
0 Remapping
GPIO0 after reset, the default is function5 to export the clock
GPIO2 U0TXD signal can be output through GPIO2 pad besides U0TXD pad
好的,那麻烦帮我看一下,这资料是不是你们官网出的,我在别处找到的,没错误吧?
