38kHz carrier signal - Sparkfun ESP32 Thing

I used the following code to generate a 38kHz signal on a nano: // toggle on compare, clk/1 TCCR2A = _BV(WGM21) | _BV(COM2A0); TCCR2B = _BV(CS20); // 38kHz carrier/timer OCR2A = (F_CPU / (IR_CLOCK_RATE * 2L) - 1); pinMode(pwmPin, OUTPUT); Now I need to do the same on an esp32 and i'm not really sure...

Re: How to wire for IrDA ?

Hi there,

I'm trying to get exactly this working with the Sparkfun esp32 Thing, but getting nowhere. It's sending the burst out from the IR, but it's junk data - i'm not sure the 38kHz carrier is being added. I know this is a little vague but have you any advice?
