Igor: Sounds like you have two problems, with the LCD being a separate one from the sync errors. For communicating with the board via IC.exe, try changing your port settings to 9600/8 data/no parity/1 stop/Xon/Xoff/FIFO buffers enabled. I don't have (...)

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? (...) (26 years ago, 29-Oct-99, to lugnet.robotics.handyboard)

Hiya all, While it was a bummer not going to Mindfest, what I did do was a robotics demo at a local SF convention in Denver. I had 6 robots there with me. Four DIY types (one used LEGO pneumatics for a scoop) a Parallax BoE-Bot and a Mindstorms kit. (...) (26 years ago, 29-Oct-99, to lugnet.robotics)
