(...) Looks like you got too many semi-colons. Take out the semi-colons on all the while lines where you want the while to do the following thing. The process is getting to the "while(!start_button());" line and staying there. Also you have too many (...) (28 years ago, 3-Jan-97, to lugnet.robotics.handyboard)

Hi, I know this is an old chestnut but believe me I have searched the mail archive and nothing quite matches what I'm seeing. I have a handyboard which I made and which seems to work perfectly.

(...) OK, well I think it is isolated at the pseudo-MAX232 chip. Did you get the +10 v power supply pin on the p-MAX ok? It's at pin 2. Measure it w/r/t ground and you should get +10v. Before you order a real Maxim, check the polarity of your (...) (28 years ago, 3-Jan-97, to lugnet.robotics.handyboard)

Here is the relevant part of the test instructions: Finally, the MAX232's ability to transmit data to the host computer is tested. Again using pin 7 of J9 as a ground reference, measure the voltage at pin 3 of J9. This is the MAX232's serial output. (...) (28 years ago, 3-Jan-97, to lugnet.robotics.handyboard)

Happy New Year! I'm putting together a HandyBoard and am stuck at the point where pcode_hd.s19 is downloaded. Some details: Have a chip labled SIPEX SP232ACP as a substitute(?) for MAX232. During downloading using DLM the board syncs OK but (...) (28 years ago, 2-Jan-97, to lugnet.robotics.handyboard)

(...) We have successfully integrated a Traxxas RC car with the Handy Board. The vehicle uses a standard servo for steering and an electronic speed control (same behavior as a servo.) Since the HB can control 2 servos this works well. In this case (...) (28 years ago, 2-Jan-97, to lugnet.robotics.handyboard)

Both are very fast. Unfortunately, both are (...) (28 years ago, 1-Jan-97, to lugnet.robotics.handyboard)
