Thankyou for your kind response to my student Javaid Iqbal on errors in using floating point divide within IC software.

Hi all! I am using the handyboard as a PID controller. I wrote my own program it didn't perform really well. Is there any resource about PID using HB so I can furnish my program? Thanks a lot!! Keith (26 years ago, 22-Nov-98, to lugnet.robotics.handyboard)

if you are not trying to divide numbers of great precision(many significant figures), then you can try multiplying by some order of 10, performing your division, then dividing by that same order of 10. i have used this before, but not for the same (...)

(...) I've asked for help with the floating point bugs in IC before, and nobody seems to care. Unfortunately, I've come to not use IC floating point variables at all, since I can't trust them. It's all very frustrating since none of the IC versions (...) (26 years ago, 21-Nov-98, to lugnet.robotics.handyboard)

Dave As far as connecting the grounds, that just means that the HB and the motors must share a common ground. The H-bridges need to reference the direction and PWM signal to ground and if that ground reference is not the same as the HB's the motors (...)

|

I'm still not sure what caused the problem, but a new bootstrap/reinstall of the pcode seems to have fixed the problem. I can now successfully use the printf function. Odd though, that that was the only command that wasn't working correctly. Todd (26 years ago, 21-Nov-98, to lugnet.robotics.handyboard)

Check B. G. Micro 800-276-2206 www.bgmicro.com I would not be too concerned with the actual part number, just look for an Infared sensor or remote control sensor. Also get the pin outs as these may be different. Also have you considered using fewer (...) (26 years ago, 20-Nov-98, to lugnet.robotics.handyboard)
