Displaying temperature Setpoints

[aratti]

Put yours subrouteenes at the end of your code, never at the beginning!

Modify your If then in the following manner:

if maindisp = 1 then
write 0 , sethighp
pause 10
write 1 , sethighp
mode = 1
maindisp = 0 ' reset flag
endif

Otherwise it will write at every cycle and in this case you do not need the " IF Then " statement. Set your flag to 1 when writing is needed

Yours code for reading key:

getkey:
pause 50
keyin = portc
return

You read the status of the all 8 inputs, than you need to decode to find which key has been pressed.

Are you pulling up your inputs using normally closed switches? otherwise with this code you have to pull down your inputs.
