# ESP12 Flasher for M5Stack-ESP12-Shield



PIN Mapping:

============

         M5Stack | ESP12

     ------------+------------

        16 (Rx2) | D1 (TX0)

        17 (Tx2) | D3 (RX0)

              12 | D0 (FLASH)

              13 | RESET

            3.3v | VCC

            3.3v | D2

            3.3v | CH_PD (EN)

             GND | GND

             GND | D15

             



Using the Arduino IDE:

======================

   - Compile & Upload this sketch on the M5Stack

   - Change board to ESP8266

   - Set Baudrate to "115200"

   - Set Flash Mode to "DOUT"

   - Set Reset Method to "no dtr (aka ck)"

   - Open your ESP8266 sketch

   - Hit the Button B on the M5 so the ESP8266 waits for flashing

   - Hit the Upload button

Also acts as a serial bridge (115200) after flash timeout.
