I'm using IC to program the Handy Board but I have run into a slight problem. How do I undefine a "main" from the board so that I can define another "main" if I can't remember the name of the window I downloaded that had the wrong "main" on it? (...)

Hello all, If I may trouble one (or two) of you electronics gurus out there... I have a Dinsmore 1490 compass. It has twelve leads for a total of 4 sensors. I am hoping that I can at least get a rough eight point heading from this thing. I would (...) (25 years ago, 2-Jun-99, to lugnet.robotics.handyboard)

| | Sharp GP1U58 Hack without modifing my board
|
|
I have two questions. I hope someone can help. First: Is there a way to use a Sharp GP1U58 hacked to give analog values WITHOUT cutting the trace to the resistor pack on the analog inputs? Perhaps using an OP AMP. Also would removing the resistor (...) (25 years ago, 2-Jun-99, to lugnet.robotics.handyboard)

I accidentally hit "download window" and it defined a "main" function onto the board. How do I undefine "main" so I can define a new one? I don't remember the name of the window I downloaded. Thanks for your help! Salpi (25 years ago, 2-Jun-99, to lugnet.robotics.handyboard)

Has anyone had any success at converting the output of this sensor to inches or some other linear unit of measure? It would be very helpful if somebody assisted (...)

Thank You, i have downloaded the circuit from the URL : www.hooked.net/~jfon...nterface.p df , and i have another question, can the 5 V. pin of the analog input drive this circuit, How much current can draw this pin? Maybe I must take the power (...) (25 years ago, 1-Jun-99, to lugnet.robotics.handyboard)

(...) Allow me to be redundant (others on the list are tired of hearing about it I'm sure): Go to www.eskimo.com/~archer, and snag the HC11 patches to the GCC-2.8.1 compiler. In there is a readme that tells how to get it going on a Linux box. It (...) (25 years ago, 1-Jun-99, to lugnet.robotics.handyboard)

The GP2D02 output is an exponential curve so plugghing the a bunch of samples into a TI calculator and solving for the coefficients gave me the following two equations for two different sensors. G is 255 minus the ouptut reading from the GP2D02. (...) (25 years ago, 1-Jun-99, to lugnet.robotics.handyboard)

I've been using Interactive C with the Handy Board and like the convenience of C commands. I am now trying to work with Motorola's HC11EVBU evaluation board (same 6811 chip, different interface). It has a program called BUFFALO which is a (...) (25 years ago, 1-Jun-99, to lugnet.robotics.handyboard)

Hello everyone... If I may be permitted to ask your input on some of the following... I have implemented a Polaroid sonar module and a GP2D02 IR ranging unit on a R/C servo actuated pan/tilt mechanism. I can put in "scan_long(45.0)" or (...) (25 years ago, 1-Jun-99, to lugnet.robotics.handyboard)
