I got my program to a point where I needed to test so I ran it in the uVision simulator. It was flawless. I fired up my Nohau emulator and ran it on our new PC board. Perfect.
I burned a chip (89C51RD2) and popped it in the board...nothing.
Since I am now the only embedded guy in the shop I work alone I have no one to bounce ideas off. So I've come here.
The oscilloscope shows that timer_0 is running, and my ISR is OK because the watchdog strobe is happening and the timer values are being reloaded.
Has anyone seen this before? Do you have a suggestion of of path to find the differences between the simulated and emulated situation and running on the board?
Hi, very nice project, congratulations! Do you have the source code of the program? Thanks
Very nice what project? The one with nothing happening?
Yes, I do. Thanks for asking.
