Mike, Chuck McManis may have answered your request, but in case you still want sample code I am attaching an example code that prints to the HandyBoard display.

  Re: Controlling a DC motor 3
 
(...) Actually, the frequency is somewhat important. The faster you switch, the more power will be lost to the switching of the power transistors and the filtering effect provided by the inductance of the motor. At the other extreme, frequencies (...)

  Re: Cannot download pcode on a Mac G3
 
I have a 266 G3 minitower, and I have the identical problem. The only way to solve this is to let IC die, not reset the HB and then run IC again. It complains to can't talk to the HB, and then I reset the HB and all works fine. Kinda odd, but it (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)

This appendix contains a complete description of (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)
 
  Re: Motor Drivers in 7000 - 7fff
 
Jaron, (...) This was done (obviously) to save extra decoding circuitry needed on the board. That is, if the handy board needed to assign (say) 7000 as the motor then sixteen address lines need to be decoded (binary 0111 000 000 000). Yet with the (...)

  Working with a different compiler 2
 
Howdy All, I am in a happy mood today. I finally got to the 'hello world' stage. All I had to do was count the number of interrupts, * 2 (16 bit addresses), subtract this from BFFF which is the reset vector and thus supply BFD6 to my linker to start (...)

  Re: LCD Addressing - & - Expanded Mode
 
From the driver code I recently sent out: * LCD Connections on the Handyboard * PORTB bit 0 - R/W * PORTB bit 1 - RS (Register Select, 0 = instruction) * PORTC 8 bits of Data * PORTA bit 4 - E clock (...) That is correct, the LCD is NOT memory (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)
