You can build a stepper motor controller on a separate circuit board, then remove the motor control IC's off the handy board and use the output signals to control your stepper. Will have to write a program to run it. you will need a min of 4 outputs (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)

The nonlinearity has to due with the characteristics of your motor. You will find that a single step of power at the low end has a greater effect on the speed than a single step at the high end, as the motor approaches its top speed. The (...)

The reason you don't need a pull up resistor for the Handy Board is because the Handy Board has built in 47k pull up resistors on the digital inputs! -----Original Message----- From: MAR ERICSON <mar@cooper.edu> To: Darkman <lroska@cyberus.ca> Cc: (...)

Hello everybody, Is something wrong with this code or is it IC? { int a[4][4], i; for (i=0; i<4; i++) { a[i][i]=i; } } When I type this at the IC prompt it complains: Downloading 79 bytes (addresses C200-C24E): 79 loaded COMPILER ERROR!: 2 extra (...)

well....I might be the way you are powering the sensors ??? Maybe luck ???? :)))))) Actually I don't why you don't need any of those supporting parts. A short question ...For what range are you using the sensors (are you using the binh signal) ?? We (...) (26 years ago, 22-Apr-98, to lugnet.robotics.handyboard)
