Hi , have been looking at some examples of IR decode , i am new to pic basic programming , so some input on the code to decode the holtec HT6221/6222 using a pic would be appreciated ,
the input will be from IR reciever going Low for signal
I did look at using 12f508/ 509 pic , although its not got PWM , , found your example on here to generate the 38Khz carrier and will give it ago for a test.
My requirement is save the received IR code to PIC ( assumed to be a valid code received , but not to decode it , and send it out a 1 sec or so after power is applied to the pic ,
I thought of just saving all highs and low transitions from the IR reciever to a counter array and set a timer for a set time period of say 10uS then generate the output of highs and lows as required from the saved counters or timer values , clearly allowing for no data input ( eg all high when no IR signal
Not sure if i can save that amount of data to this PIC 12F508 / 509 in this manor or a better approach is required
Please advise
Cheers
