Hi John, I am interested in your handyboard ! I'm curious, when you say your board only has one motor chip is that something you added on or does that mean it only has one of the four outputs for DC motors, that usually comes with the board. Or does (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

| | Re: Battery Level Indicator
|
|
(...) When I first got my HC11EVB I ran 12V straight into the E port (one of the pins), and was sure I ruined the chip. I called the tech support person at motorola, and he said 12V on a A/D port should be no problem. Sure enough it all still (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

1. yes, you probably killed your analog 5. the analog inputs are very sensitive to over voltage. if your ran more than +5v directly into the input, you probably killed it. next time you're playing with funky voltages, put a 5K resistor in series (...)

Ummm, Hi all I'm looking for a circuit that will interface a photo transistor or a photo diode to a digital input. I tried a photocell in an analog port but it's too slow, I want to use a *visible* light pulse as an accurate trigger: ie. input (...) (26 years ago, 20-Jan-99, to lugnet.robotics.handyboard)

Handy-folk, I recently discovered that there is an experimental version of Java for the 68HC11 microcontroller. Cool! It has been in field testing since June, and looks promising.

i am unable to reproduce the problem. perhaps comms between IC and your board are still unreliable. try writing a program that repeatedly prints to the LCD screen the result of 123 * 2. my guess is that it will work perfectly. also, make sure you (...)

| | Re: digital and analog port on HD

(...) A digital port can't have the capability of an analog port, since it has only one bit of information with which to work. (A 256-value analog port has eight bits.) You could perhaps hook an analog sensor up to a digital port using some sort of (...) (26 years ago, 18-Jan-99, to lugnet.robotics.handyboard)
