how can i obtain the current values of registers like accumulator,B,stack pointer,PSW,DPTR,etc in C?? i am currently working on a trainer/development kit for 8051..One of the commands to be executed is R<CR> Once this command is executed,the values of all the registers like A,B,SP,PSW,DPH,DPL,R0,R1,R7 should be displayed on screen...how do i retrieve these register values in C?
I know very little about C51 but maybe you can try something like this: Write an assembly-only module that exports functions that return the register values you need. Write C code to call these functions. Put these into the same project. Link. Run.
