|
||||
|
||||
- Micro-SD card interface
|
||||
- TFT display interface

<b>*</b> Default configuration cannot be used or is not available at all when optional configuration is used. For example, when the TFT is connected, GPIO32 is used as **TFT_LED** signal and ADC_LINE(4) is not available.
|
||||
|
||||
@note When the TFT display is connected, add the following line to the makefile of the application to enable the according default board and peripheral configuration:<br>
|
||||
```
|
||||
USEMODULE += esp_lolin_tft
|
||||
```
|
||||
|
||||
For detailed information about the configuration of ESP32 boards, see section \ref esp32_comm_periph "Common Peripherals".
|
||||
|
||||
### <a name="optional_hardware"> Optional Hardware Configurations </a> [[TOC](#toc)]
|
||||
|
||||
MRF24J40-based IEEE 802.15.4 radio modules and ENC28J60-based Ethernet network interface modules have been tested with the board. You could use the following code in your \ref esp32_app_spec_conf "application-specific configuration" to use such modules:
|
||||
|
||||
```
|
||||
#ifdef BOARD_ESP32_WEMOS_LOLIN_D32_PRO
|
||||
|
||||
#if MODULE_MRF24J40
|
||||
#define MRF24J40_PARAM_CS GPIO15 /* MRF24J40 CS signal */
|
||||
#define MRF24J40_PARAM_RESET GPIO2 /* MRF24J40 RESET signal */
|
||||
#define MRF24J40_PARAM_INT GPIO13 /* MRF24J40 INT signal */
|
||||
#endif
|
||||
|
||||
#if MODULE_ENC28J80
|
||||
#define ENC28J80_PARAM_CS GPIO15 /* ENC28J80 CS signal */
|
||||
#define ENC28J80_PARAM_RESET GPIO2 /* ENC28J80 RESET signal */
|
||||
#define ENC28J80_PARAM_INT GPIO13 /* ENC28J80 INT signal */
|
||||
endif
|
||||
|
||||
#endif
|
||||
```
|
||||
For other parameters, the default values defined by the drivers can be used.
|
||||
|
||||
@note
|
||||
- Only a few GPIOs are available for external hardware on the Wemos LOLIN D32 PRO. Therefore, MRF24J40 and ENC28J60 based modules use the same GPIOs and only one of these modules can be used simultaneously.
|
||||
- The **RESET** signal of MRF24J40 and ENC28J60 based modules can also be connected to the **RST** pin of the board (see \ref esp32_wemos-lolin-d32-pro_pinout "pinout") to keep the configured GPIO free for other purposes.
|
||||
|
||||
### <a name="pinout"> Board Pinout </a> [[TOC](#toc)]
|
||||
|
||||
The following picture shows the pinout of WEMOS LOLIN D32 PRO board as defined by the default board configuration. The light green GPIOs are not used by configured on-board hardware components and can be used for any purpose. However, if optional off-board hardware modules are used, these GPIOs may also be occupied, see \ref esp32_wemos-lolin-d32-pro_table_board_configuration "optional functions" in table board configuration.
|
||||
|
||||
The corresponding board schematic can be found [here](https://wiki.wemos.cc/_media/products:d32:sch_d32_pro_v2.0.0.pdf).

|
||||
|
||||
## <a name="flashing"> Flashing the Device </a> [[TOC](#toc)]
|
||||
|
||||
Flashing RIOT is quite easy. The board has a Micro-USB connector with reset/boot/flash logic. Just connect the board to your host computer using the programming port and type:
|
||||
```
|
||||
make flash BOARD=esp32-wemos-lolin-d32-pro ...
|
||||
```
|
||||
For detailed information about ESP32 as well as configuring and compiling RIOT for ESP32 boards, see \ref esp32_riot.

|

*
|

* 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
|
||||
* ```
|
||||
* 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 \ref esp32_comm_periph "Common Peripherals".
