Has anyone ever seen an authoritative document on using debug functions in uVision3? It could be a powerful tool if I knew how to use it, but what little information I have come across is scattered across 2 hardcopy manuals, a bit more in the help file system, and smatterings in the Keil Knowledgebase. Here are clues, not documented anywhere, that I have discovered by trial and error: - If the last line of a .ini file containing function definitions does not end in a CR/LF, you get a "syntax error". - The "Breakpoint Set (BS), and "Go" (GO) commands may be executed from the command line, but not inside a function. - If you access program variables from the function, you must halt execution at a point in the program where they are all in scope before you load the function with an "include" command. Otherwise you get another "syntax error." - When you define and/or when you invoke a function, you must terminate its name with a pair of parentheses. When you "kill" the function, you must omit the parentheses. Otherwise, you get another one of those ubiquitous "syntax errors". - It could be that everything is a syntax error in this domain. The messages are that useful. :-} Perhaps if we all pool our insights, we will have a running start on a manual. ============================================================ Gary Lynch | To send mail, no$pam in domain name lynchg@no$pam.com | must be changed to stacoenergy.
Thanks for telling us the manual and tools weaknesses. We have tried to improve it by new examples. Did you saw already: http://www.keil.com/support/man/docs/uv3/uv3_simulation.htm Reinhard
We may have a semantic gap here. The material you reference seems to be about signal functions, which as best I understand, are only available in the simulator. They are used to generate input numbers that look like peripheral ports to the application. I am using what the manual calls the "target hardware debugger" running on my own board (flash programmed via JTAG interface). My signals come directly from the hardware itself. I have never used the simulator at all. Is a user function something I can use with the hardware debugger capability, or am I trying to force my cat to haul a piano upstairs? It isn't obvious from the manual. ============================================================ Gary Lynch | To send mail, no$pam in domain name lynchg@no$pam.com | must be changed to stacoenergy.
