The former FLASH_MODE_{DOUT,DIO,QOUT,QIO} defines are replaced by the corresponding CONFIG_FLASHMODE_{DOUT,DIO,QOUT,QIO} and CONFIG_ESPTOOLPY_FLASHMODE_{DOUT,DIO,QOUT,QIO} as used by the ESP-IDF. This is also needed for the migration of defining flash mode in Kconfig.

* @brief Peripheral MCU configuration for MH-ET LIVE MiniKit for ESP32
|
|
* @{
|
|
*
|
|
* The MH-ET LIVE MiniKit for ESP32 uses the ESP32-WROOM-32 module. It is
|
|
* a very interesting development kit as it is available in the stackable
|
|
* Wemos D1 Mini format. Thus, all shields for Wemos D1 mini (ESP8266
|
|
* platform) can also be used with ESP32. All GPIOs are broken out so that
|
|
* it can be configured very flexibly.
|
|
*
|
|
* For detailed information about the configuration of ESP32 boards, see
|
|
* section \ref esp32_peripherals "Common Peripherals".
|
|
*
|
|
* @note
|
|
* Most definitions can be overridden by an \ref esp32_application_specific_configurations
|
|
* "application-specific board configuration".
