Expand description

@brief Register RMT interrupt handler, the handler is an ISR.

   The handler will be attached to the same CPU core that this function is running on.

@note If you already called rmt_driver_install to use system RMT driver, please do not register ISR handler again.

@param fn Interrupt handler function. @param arg Parameter for the handler function @param intr_alloc_flags Flags used to allocate the interrupt. One or multiple (ORred) ESP_INTR_FLAG_* values. See esp_intr_alloc.h for more info. @param handle If non-zero, a handle to later clean up the ISR gets stored here.

@return - ESP_OK Success - ESP_ERR_INVALID_ARG Function pointer error. - ESP_FAIL System driver installed, can not register ISR handler for RMT
