Configuration

Please use ttgo-t7-v14-mini32 ID for board option in “platformio.ini” (Project Configuration File):

[env:ttgo-t7-v14-mini32]
platform = espressif32
board = ttgo-t7-v14-mini32

You can override default TTGO T7 V1.4 Mini32 settings per build environment using board_*** option, where *** is a JSON object path from board manifest ttgo-t7-v14-mini32.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:ttgo-t7-v14-mini32]
platform = espressif32
board = ttgo-t7-v14-mini32

; change microcontroller
board_build.mcu = esp32

; change MCU frequency
board_build.f_cpu = 240000000L
