Value:

((struct joybus_esp32 *)(bus))

Macro to cast a generic Joybus instance to an ESP32 Joybus instance.

Function Documentation

joybus_esp32_config_default()

struct joybus_esp32_config joybus_esp32_config_default ( gpio_num_t gpio )

inlinestatic

Build an ESP32 config with default values.

Parameters

gpio	the GPIO pin to use for the Joybus data line

Returns

a config with the given GPIO and a nominal frequency

joybus_esp32_init()

int joybus_esp32_init	(	struct joybus_esp32 *	esp32_bus,
		struct joybus_esp32_config	config )

Initialize an ESP32 Joybus instance.

Parameters

esp32_bus	the ESP32 Joybus instance to initialize
config	the configuration to use, eg. from joybus_esp32_config_default()

Returns

0 on success, a negative joybus_error on failure
