I am trying to make a remote for my sat receiver.
The channel upcode works, but then when I insert the code to read my push buttons it will not.
I have even put the upcode command before my “GetBtn” routine.
I have tried serial printing all of the timer registers to see if anything is going wrong here.
Here is my code::-
/*********************************************************************
TV remote for edision sat reciever
Uses:-
Nokia 3310 display, ProMini running at 16mhz and 2 pencels, 3.1V - might be borderline!
ledpin needs to be earthed on my display (pinouts diff order too)
leds seem to light ok with 400 ohm (prob 6 mA on 3V)
Contrast setting: Ada set it to 50.
40 I see nothing
60 v good contrast without backlight (daytime no better with backlight)
IR led with 75R for 3V
Pins:-
DO:-
settings menu - at mo hitting ok on settings will prob crash
backlight code

I have tried tried to highlight the code and use the code symbol at top of page, but I can not highlight it - sorry.
This is what happens:-
If I comment out the two lines where I digitalread (lines 71 and 73), then when I transmit the code (at the end of SetUp, line 56, “XChnUp” the sat receiver goes up one channel.
If I uncomment the digitalread (so I can check my button state), then I see nothing at the IR led when I look at it with my camera.
Any help would be appreciated! Thank you
