Detailed Description

Definitions for Wemos stackable hardware modules (shields)

The board can be used with lots of optional stackable hardware modules. This file contains the default configurations for those hardware modules that have been tested. Most of these configurations can be overridden by an application-specific configuration.

The configurations of the respective hardware modules only take place if the corresponding driver modules are used.

MRF24J40 shield configuration
Configuration for the MRF24J40 shield when module `mrf24j40` is used. MRF24J40 module uses SPI_DEV(0) and according pins on this board to be compatible with the Wemos D1 mini MRF24J40 shield. Note To keep an additional GPIO free, the ENC28J60 RESET signal can be connected to ESP32 Reset pin.
#define	MRF24J40_PARAM_SPI SPI_DEV(0)
	SPI_DEV(0) is used (fixed)

#define	MRF24J40_PARAM_SPI_CLK SPI_CLK_1MHZ
	SPI bus speed used (can be overridden)

#define	MRF24J40_PARAM_CS GPIO26
	MRF24J40 CS signal (can be overridden)

#define	MRF24J40_PARAM_INT GPIO17
	MRF24J40 INT signal (can be overridden)

#define	MRF24J40_PARAM_RESET GPIO16
	MRF24J40 RESET signal (can be overridden)

SD-Card shield configuration
Configuration of the SD-Card interface when module `sdcard_spi` is used. SD card interface uses SPI_DEV(0) on this board to be compatible with the Wemos D1 mini micro SD card shield. The D8 pin (GPIO5) is used as default CS signal. Note Please override the definition of CS pin by an by application-specific configurations according to your solder bride configuration.
#define	SDCARD_SPI_PARAM_SPI SPI_DEV(0)
	SPI_DEV(0) is used (fixed)

#define	SDCARD_SPI_PARAM_CLK SPI0_SCK
	SPI_DEV(0) SCK is used (fixed)

#define	SDCARD_SPI_PARAM_MOSI SPI0_MOSI
	SPI_DEV(0) MOSI is used (fixed)

#define	SDCARD_SPI_PARAM_MISO SPI0_MISO
	SPI_DEV(0) MISO is used (fixed)

#define	SDCARD_SPI_PARAM_POWER GPIO_UNDEF
	power control is not used (fixed)

#define	SDCARD_SPI_PARAM_CS SPI0_CS0
	SD-Card CS signal (override it)
