Fred, Thanks for the info on how IC determines whether to auto-start a program or not. Based on your suggestions ---- I just finished downloading the open-source (free) version of IC. I had been running Newton Labs 3.1 and most recently 3.2. I (...) (23 years ago, 2-Jan-02, to lugnet.robotics.handyboard)

Hi all, I've been trying to find Max Davies IR routines, but the link off the handyboard site is broken. Anyone know where I could get my hands on the code for these routines? Thanks in advance for the help. (23 years ago, 22-Dec-01, to lugnet.robotics.handyboard)

Dan, Thanks for hanging tough on this problem.....I'm feeling really inadequate on this one. I downloaded your revision of my program and it did not help.

John, I added a little sub routine to your program, see if you can use it this way. Probably not, but hey it's worth a try.

John, I have 105 of the Toshiba 68HC11's, and I use them in all sorts of products with great results. I don't think the chip is the problem either. It's begining to look like the pcode, I take it that you have the full new version. I have never (...) (23 years ago, 2-Jan-02, to lugnet.robotics.handyboard)

Dan, My 68HC11 chip has the following numbers: TMP68HC11A1T-3 and is, in fact, labeled TOSHIBA. I have two of these chips and I've tried both of them with exactly the same result. I've also changed the RAM chip, reloaded everything and no change. My (...) (23 years ago, 2-Jan-02, to lugnet.robotics.handyboard)

Dan, Thank you for the suggestions. Like you, I tried removing the white space(s) and it did not help. Yesterday, I installed a new memory chip and a new 68HC11.....same problem.

John, I just loaded up your version of the code you posted, It worked fine on reset. I took out the white space just to see, and it worked fine too! I would say that your memory is bad or the lm2931 -5 is bad. Something is causing total reset (...) (23 years ago, 1-Jan-02, to lugnet.robotics.handyboard)

Fred, I double-checked, and my " main() " program (filename: jrm1.c) is all lower case letters. I confirmed case sensitivity by trying to call the " main() " file (filename: jrm1.c) which has been downloaded to the HB by typing " Main() " on the PC. (...)

I wonder if it's because you've capitalized "Main()". C is case sensitive so main != Main. try it making your main program lower case and see if that works. Fred (...) (23 years ago, 30-Dec-01, to lugnet.robotics.handyboard)

John, a couple things. 1. when you quit and restart IC, it forgets what programs you may have loaded into the HB. so that explains your #4 case below. 2. IC has its own way of storing vectors for user code like your main() program, so you should not (...) (23 years ago, 30-Dec-01, to lugnet.robotics.handyboard)
