What's the trick to make the C51 simulator increment timers in realtime? Ive tried setting the xtal value appropriately, on the target panel. (I just need the simulation's blink led freq to have the same period as the real target) Peter
May I add a comment just to establish some perspective? I remember writing in asm51 (no C compiler yet), using my own DOS batch files as my make utility, and debugging the code with port pins and an oscilloscope. The first time I used PK51 I was so happy and I couldn't believe how much this tool allowed me to do. It was like being a caveman who discovers fire, the wheel, and refrigeration all at once. When a slick new 51 variant comes out sure I'd like to have the new features supported in simulation right away but that never holds me back, the Keil tools are great.
