Yes im aware of the hardware serial ports, just got frustrated trying to dechipher what pins and how to use them exactly as the esp dev board pins are not in order and in general a cluster fuck to wade through😅 i plan to work that out and switch to hardware at a later date, but its only 9600 baud so no problems as of now. Yes u understand correct. Ill go copy some code. Im not sure how to post it as I've seen ppl be scolded for copy paste😂
i cant reply for 17 hours cus new member. heres the code i quickly modified to output a triplet. ill have to go back through and add a function to show the other values if i request them.
