Peripheral MCU configuration for Wemos LOLIN D32 Pro.

Wemos LOLIN D32 Pro is a development board that uses the ESP32-WROVER module which has a built-in 4 MByte SPI RAM. Most important features of the board are

  • Micro-SD card interface
  • LCD interface
  • SPI RAM 4 MByte

Furthermore, most GPIOs are broken out for extension.

When the TFT display is connected, add 

1
USEMODULE += esp_lolin_tft
to the makefile of the application to use the according default board configuration.

For detailed information about the configuration of ESP32 boards, see section .

Note

Most definitions can be overridden by an .

ADC_GPIOS

Declaration of GPIOs that can be used as ADC channels. 

1
{ GPIO36, GPIO39, GPIO34, GPIO35, GPIO32, GPIO33 }

GPIO35 is used to measure V_BAT and is therefore not broken out.

Note

As long as the GPIOs listed in ADC_GPIOS are not initialized as ADC channels with the adc_init function, they can be used for other purposes.

DAC_GPIOS

Declaration of GPIOs that can be used as DAC channels. 

1
{ GPIO25, GPIO26 }

Note

As long as the GPIOs listed in DAC_GPIOS are not initialized as DAC channels with the dac_init function, they can be used for other purposes.
