need help on understanding RMT example

[manoj15]

Code: Select all

	 rmt_item32_t* item = (rmt_item32_t*) xRingbufferReceive(rb, &rx_size, 1000);
	 
	 int res = nec_parse_items(item + offset, rx_size / 4 - offset, &rmt_addr, &rmt_cmd);
 
 

understand that rx_size contains the received RMT item length, what is the reason of it to get divide by 4 ?

Hi,
A `rmt_item32_t` type element is 4 byte. So the element number is `rx_size / 4`.
