Hi Everybody, Ensio, I'm having a very similyar problem, but with an interesting twist! Check this out! I still don't have any idea what is going on here... None of these have expansion cards.

Hi Greg, It all depends. Various features of the HB can be turned on and off to change the amount of work done in the main ISR. By default the code uses 300ms to execute. The file lib_hb.c provides the following: /***...***/ /*** System Interrupt (...) (25 years ago, 2-Nov-99, to lugnet.robotics.handyboard)

Hey Group, I'm currently trying to get assembly files to work with my HB, i've discovered that the exe I need; as11_hb.exe only runs on UNIX, so you have to use (URL) to assemble the files, which I might say is a little inconvenient.

Hi, For a project I'm working on, I need to track the output of one hundred (100) photocells. I don't need great accuracy on any of them, but maybe a ten-step resolution at the most.

Greg: You can run assembly from within Interactive C, so if IC isn't fast enough for you, you can build in something that is. However, IC will execute pretty quickly in terms of how fast steppers run, so it could be that IC will work for you as-is? (...) (25 years ago, 29-Oct-99, to lugnet.robotics.handyboard)
