I am not sure how you know it is the bluetooth and not a subsequent loop, both routines have the same printf to the display. Also, there are a number of...
Hey Jim, Turns out that when the bluetooth gets connected, it sends some sort of interrupt that crashes the main program. So by not connecting the RJ-11 until...
I don't think you have a global array if they don't show up in the upload array window. This is a minimal program that compiles an array of structs. the struct...
Hi Guys I've joined this group lately!!! I'm an amateur at High school From Egypt !! So I'd like to know the basic steps of programming using the Handy Board...
Anyone care to post some sample code for quadrature encoders? I'm working with Wheel Watchers on a differential driven robot. My goal is to get my robot to...
I would also like to look at programs like Dan is trying to use. Hope you can list your code on the list to help others understand. Thanks. Terry Gathright ......
Dan, I had posted a quad encoder icb and source a couple years ago in the files section, I uncovered a bug in the velocity calculations and replaced the set...
Jim, I haveyour quad encoder files intalled in my directory and have been using them. I am recommending to the botball guys that they should add your version...
Dan, You are correct, I did not post an actual example. The ideal of code to "accurately navigate a robot and return to it's original spot" is roughly...
Hi, Is there any docs on communication protocol for serial comm to HB. I would like to test basic communication like, 1. Is HB preset and responding? 2. Beep ...
... reference manual says in bootstrap mode it expects an 0xFF at either 1200 or 7800 baud followed by 256 bytes of machine code. what happens from there is...
How are you programming your Handyboard? If you are using Interactive C the functions you describe are invoked from the interaction window in communication...
http://tech.groups.yahoo.com/group/handyboard/files/HB%20%20Dual%20Quadratur e%20Encoders/ This was from a while ago. Hope this helps! :-) Ericson Mar mailto:...
Ericson, Thanks, one of the problems with my encoder approach is it obviates any use of the standard sonar routine on the handyboard in IC (the sonar requires...
I have the basic customized read/write serial port module that I would like to use to communicate with HB. Here is want I would like to do, Take a .ic program...
Hi, I am trying to identify the links between different programs available, 1. Write ASM Program 2. XXXXX.exe will convert .asm to .s19 file 3. Download .s19...
You guessed correctly! The robot that uses this code has 8 Senscomp (previously Polaroid) Sonars. That may have been why I used this method...it was a while ...
Remember IC is not C. it is an interpreted language with a C-like syntax. There are no .ic source to .s19 compilers that I am aware of. There are however, C,...
The only item of note is that all current IC versions assume you have an expansion board on your Handyboard. (analogs 0 and 1 are reserved for the expansion...
I just wanted to thank Jim and Ericson for their code samples, I'm making headway slowly but surely on this project. I only get a few hours a week to play...
Dan, Sounds like an interesting project. With this kind of navigation, one key point is some kind of error elimination scheme. That is, some additional "known...
Can anyone help me? I was trying to get more current for my motors so I decided to piggyback the TI motor driver chips with a heat sink. However when I did...
