Todd, There are Two options on the Windows program HBDL.EXE 1. Download - This downloads a bootloader then a file to the external RAM of the handy board. 2. Burn - This (attempts) to download a file to the HandyBoards 68Hc11 internal EEPROM. Thus (...) (24 years ago, 28-May-00, to lugnet.robotics.handyboard)

Do you mean that when you turn on the Handy Board, the motors start to run spontaneously? I used to have that problem, too, but only when there was no program yet loaded. I saw a message on this mailing list a few months back that suggested a remedy (...) (24 years ago, 27-May-00, to lugnet.robotics.handyboard)

You might try something like: while( 1 ) { if( start_button() ) printf( "you pressed the start button\n" ); else printf( "\n" ); msleep( 250L ); } or simply: { start_press(); printf( "you pressed the start button\n" ); } -- Will (...) +---...---+ | (...)

Just got my handyboard, and I am new to programming, so I have a probably simple question for you all.

| | Re: Digital outputs.
|
|
You can use solid state relays with 5 VDC inputs and DC outputs to control large loads. The inputs require very little current. It is less expensive to build transistor switches, which will do the same thing, but obviously much simpler to use (...) (24 years ago, 25-May-00, to lugnet.robotics.handyboard)

How would I go about making the digital outputs capable of controlling a higher current than the 5 ma that is standard? Can a switching transistor be controlled by them?

I'm still at my servo question :) the 3 servo routines so far use "normal" digital outputs. There are, according to the FAQ, 4 extra outputs I could use (SPI J6). Does this mean that I could write my own routines to drive 4 extra servos using these (...) (24 years ago, 23-May-00, to lugnet.robotics.handyboard)

Follow this link for data about the GP2D12. At the bottom, there is another link for Handy Board interfacing information. You have to cut a trace because the analog inputs on the Handy Board are connected to pullup resistors. The GP2D12 won't work (...) (24 years ago, 20-May-00, to lugnet.robotics.handyboard)
