I have just join this forum. I am learning ccs c. Day by day progress.
I have done a clock (ds1302-ds18b20 and 2x16 lcd). It's classic but I'm learning. I did time and temperature problem. But I didn't know how can I change variables (hour,minute,day,month,year,daysofweek). I want to use 3 buttons to change variables. (adjust,reverse,forward ) When I push adjust button a cursor come or blink variable. Then I want use change variable with reverse and forward buttons. Then when I push again adjust; cursor goes to other variable .
My trial time and temp. ok but variable don't change. Thank you for your help.
