Console Peripheral

Console Peripheral is used to control the Audio application from the terminal screen. It provides 2 ways do execute command, one sends an event to esp_peripherals (for a command without parameters), another calls a callback function (need parameters). If there is a callback function, no event will be sent.

Please make sure that the lifetime of periph_console_cmd_t must be ensured during console operation, periph_console_init() only reference, does not make a copy.

Code example

Please refer to cli/main/console_example.c.
