Hi
I'm using a K868-AG without problems to control a TV using the internal IR emitter LEDs. I want to use the GPIO avalaible on the board to wire additional IR emitters to control few other devices.
I have been careful of IR LED polarity. I have wired it between GPIO (positive side) and GND (negative side). I have also tried to add 200ohm resistor but same, it doesn't control device ! I'm sure of my ESP code as it works fine if I change code to use GPIO wired at internal LEDs ! I have tried GPIO14 with resistor and GPIO21 without but same result, not working
Any ideas what's wrong ?
Thanks,
Vincèn
