source · pub type rmt_tx_done_callback_t = Option<unsafe extern "C" fn(tx_chan: rmt_channel_handle_t, edata: *const rmt_tx_done_event_data_t, user_ctx: *mut c_void) -> bool>;
Expand description
@brief Prototype of RMT event callback
@param[in] tx_chan RMT channel handle, created from rmt_new_tx_channel()
@param[in] edata Point to RMT event data. The lifecycle of this pointer memory is inside this function,
user should copy it into static memory if used outside this function.
@param[in] user_ctx User registered context, passed from rmt_tx_register_event_callbacks()
