 | | bugs in Rich Drushel's lock_process() library
|
|
A couple of weeks ago, students in my Autonomous Robotics course found some bugs in my lock_process() library code. lock_process() and unlock_process() were intended to work like hog_processor() and defer(), except to allow a variable duration of (...)

Hi Daniel, section 5.4 of the HandyBoard Technical Reference says that switch / case statements are not supported in IC. I do not know whether this has changed since it was released. <handyboard@media.mit.edu> escribió en el mensaje de noticias (...) (24 years ago, 31-Oct-00, to lugnet.robotics.handyboard)

crossposted from lugnet.robotics I should have added that,as I am already getting the HandyBoard, any sets containing lots of electronics (aka. Robotics Invention System...) are not the most interesting for me. I am looking for the structural stuff (...) (24 years ago, 31-Oct-00, to lugnet.robotics.handyboard)

Has anyone attempted to build a batter/power monitor interface on the Handyboard? In reading the Mobile robots book it shows that that platform supports a battery monitor to an analog port. I would like to achieve the same functionality on the (...) (24 years ago, 31-Oct-00, to lugnet.robotics.handyboard)

Yes, check out my web site nfn.no-ip.com/spazbot. It works great! I wrote the code to pull it off, it's not too hard. The code should be posted at lynxmotion, if it's not I can send you an example. (...) (24 years ago, 30-Oct-00, to lugnet.robotics.handyboard)

(...) to (...) I've used similar 555/IR detector ones. They work fine, but you have to do a lot of filtering to "get the noise out". Because of that I wrote a PIC 12C508 program that handles the noise filtering and signal processing and just sets a (...) (24 years ago, 30-Oct-00, to lugnet.robotics.handyboard)

Hi I've the same problem! I've wrote a first program to solve that, but i didn't work. Look at my message from 16. October.

Hi, The sonar code is limited to 15' since we are using a signed int. I don't want to change the timer resolution since the multitasker will run slower. The counter only supports an int right? So we can use a signed int and check the overflow flag? (...) (24 years ago, 26-Oct-00, to lugnet.robotics.handyboard)
