Detailed Description

Definitions for optional off-board hardware modules that can be used with all ESP8266 boards.

All ESP8266 boards can be used with different off-board hardware modules. This file contains the default configurations for those external hardware modules that have been tested with the ESP8266 and are preconfigured here. 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.

ENC28J60 configuration
Configuration for the ENC28J60 interface when module `enc28j60` is used. SPI_DEV(0) is always used for the the module. The only configurations that can be overridden by Application Specific Board Configuration are the CS, INT and RESET signals. Note The RESET signal can also be connected to the ESP8266 RST pin to keep an additional GPIO free.
#define	ENC28J60_PARAM_SPI SPI_DEV(0)
	SPI_DEV(0) is used (fixed)

#define	ENC28J60_PARAM_CS GPIO4
	ENC28J60 CS signal (can be overridden)

#define	ENC28J60_PARAM_INT GPIO9
	ENC28J60 INT signal (can be overridden)

#define	ENC28J60_PARAM_RESET GPIO10
	ENC28J60 RESET signal (can be overridden)

MRF24J40 configuration
Configuration for the MRF24J40 interface when module `mrf24j40` is used. SPI_DEV(0) is always used for the the module. The only configurations that can be overridden by Application Specific Board Configuration are the CS, INT and RESET signals. Note The RESET signal can also be connected to the ESP8266 RST pin to keep an additional GPIO free.
#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 GPIO16
	MRF24J40 CS signal (can be overridden)

#define	MRF24J40_PARAM_INT GPIO0
	MRF24J40 INT signal (can be overridden)

#define	MRF24J40_PARAM_RESET GPIO2
	MRF24J40 RESET signal (can be overridden)

SD-Card configuration
Configuration of the SD-Card interface when module `sdcard_spi` is used. The SPI interface with the corresponding pins used for the SD-Card interface is fixed. SPI_DEV(0) is always used for the SD-Card. The only configuration that can be overridden by Application Specific Board Configuration is the CS signal. If not defined, the default CS signal of SPI_DEV(0) is used.
#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 (can be overridden)
