Hi - I am working on debugging a CAN bus. Problem is, I've never used CAN before, so I don't even know what correct communication should look like! Does anybody have images of what the data on the CANTX and CANRX lines should look like (the lines between a CAN controller and a CAN transciever). Thanks! -Mike

Hi, (sigh) Another *@&^#($ night of "tree sitting". This gets old REALLY FAST! :-/ Anyway, between trips outside, I've been dressing up some old bits of software -- cleaning up commentary, etc. One of the things I do to help with debugging as well as making interfaces more explicit is to place DEBUG-only invariants at the start of each function that "verify" the terms of the invoc...

Hi Folk After a quick scan to look for a MCU for a particular task, I have two specific MCUs in mind, they are: Atmel ATMega32L and Motorola MC68HC908AP32. Between the two, is there anyone out there who has experience in those? Which one is better in terms of debugging, and development environment and support? Also, speedwise, which is more code efficient? Any compiler to recommend?...

I know that I've seen a TI document about this before, but a 15 minute google search left me with nothing. I am double-checking a schematic that uses an MSP430F149, and I want to ensure that I have all the pins correctly terminated for (1) correct operations and (2) access to the JTAG port for in-circuit programming and debugging. Here's what I've got: AVcc -- 3.3V DVcc -- 3.3V DV...

I am quite used to playing with PICs and JAL v2. I use the PicKit3 for programming and debugging. Now I want to learn C and AVR. I thought it may be a good idea to do both at the same time.

Now I need a progra...

Can anyone please advise what is currently the best available, most versatile, PIC development kit that includes training material for the beginner. I am considering models from Brunning, CCS and Kanda. The former has an included keypad. Does this help with programming an debugging, or is it just for projects? Any suggestions would be most appreciated. Bob

While booting, I was constantly crashing when attempting to mount the JFFS2 filesystem (see below). So, I changed the JFFS2 debugging verbosity from 0 to 2. After doing this, I have not crashed again in numerous tests. Anyone else seen this kind of behavior and have an explanation? Thank you.

What JTAG flash programmer and inline debugger should I buy to use with gnuarm on linux (fc4)? Reflashing is more important than debugging (I can always use gdbserver over a serial port). Preferably using USB or ethernet -- the Embest C3 seems to fit the bill, but I don't know if it can be made to work with gnuarm.

I have been spoilt using MS Visual Studio for the last few years. Now I am back to using gdb and ftp'ing to the target. Tell me there is a better way. Ie, compile, deploy and debug (think IDE).

Can anyone recommend a better tool to save me f...

The NXP LPC1110 starts at less than $1 for a 4KB flash part. That's cheaper than an AVR in my experience! I'm not really sure if it's all that more powerful but it's good enough for me. The thing I like is that it also has a single I/O line debugging, just like AVR's DebugWire, which isn't available on all parts and for which you need to purchase ATMEL's programmer since no one else ha...

I maintain the code for a controller based on the TMS320R2811. My system uses the boot loader to download the execuable code from a host app, so I need to know how to set breakpoints after the download is done. Someone else, long since gone, did the original development, so I missed that stage of the development. So far, I've been able to get by without a debugger, but those days are over. I a...
