the wiki here says http://www.esp8266.com/wiki/doku.php?id=esp8266_gpio_pin_allocations
0 Low
1 High
x floating
MODE GPIO15 GPIO0 GPIO2
SDIO (BootSDCard) 1 x x
UART (UploadCode) 0 0 x or 1
FLASH (NormalRunning) 0 1 x or 1
Can connecting my GPIO 2 to a servo Signal Wire cause it to go LOW? because some how my ESP8266 doen't boot when I have a servo hooked up to it. I tried to change it to RX (which is GPIO3 on ESP8266) and everything seems to work fine. But I wanna know the reason why GPIO2 didn't work.
Thank you.
p/s:http://www.goodluckbuy.com/ld-1501mg-metal-gear-digital-servo-17kg-for-rc-robot.html this is the servo, if it matters. Also GPIO-2 works when I use another servo of different type instead (I don't know its name though)
