Initialise those variables as follows d1=d2=d3=d4=d5=d6=0; above warnings will be removed. 1.c:2: error 2: Initializer element is not constant 1.c:3: error 2: Initializer element is not constant 1.c:4: error 2: Initializer element is not constant these errors are with following lines Sbit front = P0^0; sbit back1 = P0^1; sbit back2 = P0^2; Try following code might work #define front P0^0 #define back1 P0^1 #define back2 P0^2 please check logic of code if (P0^0==d4) if (back1==d5) if (back2==d6) |
