I have a C program for a DWIN display: DMG48480F021_01WTC. The display uses a 8051 microcontroller, and i use Keil (PK51 Prof. Develpers Kit Version: 9.60.7.0.) to write the C code for 8051. I wanted to use debug mode to observe in detail what happens, but there were only addresses in disassembly window.

I tried the HELLO example in Keil and in it worked fine in debug mode, i could see everything in assembly language.

This is my first project in Keil and i don’t have much experience in programming, hence i don’t know how should i approach this problem? Is this just a settings issue?

Thank you in advance!
