M5Stack GREY ESP32¶

Hardware¶

Platform Espressif 32: Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

Configuration¶

Please use m5stack-grey ID for board option in “platformio.ini” (Project Configuration File):

[env:m5stack-grey]
platform = espressif32
board = m5stack-grey

You can override default M5Stack GREY ESP32 settings per build environment using board_*** option, where *** is a JSON object path from board manifest m5stack-grey.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:m5stack-grey]
platform = espressif32
board = m5stack-grey

; change microcontroller
board_build.mcu = esp32

; change MCU frequency
board_build.f_cpu = 240000000L

Uploading¶

M5Stack GREY ESP32 supports the next uploading protocols:

• espota

• esptool

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:m5stack-grey]
platform = espressif32
board = m5stack-grey

upload_protocol = esptool

Debugging¶

PIO Unified Debugger currently does not support M5Stack GREY ESP32 board.
