Configuration

Please use esp01 ID for projectconf_env_board option in projectconf:

[env:esp01]
platform = espressif8266
board = esp01

You can override default Espressif Generic ESP8266 ESP-01 512k settings per build environment using board_*** option, where *** is a JSON object path from board manifest esp01.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:esp01]
platform = espressif8266
board = esp01

; change microcontroller
board_build.mcu = esp8266

; change MCU frequency
board_build.f_cpu = 80000000L

Uploading

Espressif Generic ESP8266 ESP-01 512k supports the following uploading protocols:

• espota
• esptool

Default protocol is esptool

You can change upload protocol using projectconf_upload_protocol option:

[env:esp01]
platform = espressif8266
board = esp01

upload_protocol = esptool

Debugging

piodebug currently does not support Espressif Generic ESP8266 ESP-01 512k board.
