I appologize for being clueless. Any help would be very appreciated. This is my first experience with writing embedded software. I'm using an ARM7 on the LPC2294 board. I have it plugged into a Phytec HD200 test board. I used uV3 as an IDE for development. So far I've successfully loaded and run the two example (blinky and Hello) programs specifically written for the lpc22xx board. I've now moved onto the CAN examples. The one I'm specifically trying to get to work is CANBlinky. It compiles and I can put it on the board without problems and it appears to be running (the LED is blinking) but I'm getting nothing from CAN2 which is supposed to be transmitting A/D data. Are there any gotchas when I try to run these CAN examples on the 2294 board? The one thing I was mucking around with was the target options. They were different than the ones in the other two examples. I tried to make them match but some of the options weren't available on the CANBlinky program. Another thing I've noticed is in being able to debug. With the other examples I was able to set breakpoints in the code and step through things. This has been EXTREMELY helpful in helping me learn and understand what's going on. But with the CANBlinky example, when I try and debug, my breakpoints are never hit and when I stop the debugger and try and step, All I ever get to see is the program pointer in the disassembler going repeating the same 5 or six lines of assembly over and over. I never get to step through the code. Lastly, does anyone have any suggestions as to resources I can take advantage of in learning the basics of programming for the ARM7? Any books for beginners or the like? I'm a bit over my head with this and it was dumped in my lap with a short timeframe to complete it. Any help would be VERY appreciated. Thanks. Josh
