Hi all, I was wondering if people would please "share" their experiences running Interactive C on Windows NT. Is anyone using the old freeware DOS IC on NT? Did you have any trouble getting it to work? Please send to the list, or me privately if (...) (26 years ago, 9-Jun-98, to lugnet.robotics.handyboard)

I had same problem, and found that if you put the include files in the same directory as your file to be complied, and then place the file in quotes (eg. #include "6811regs.asm") it will compile. John (...) (26 years ago, 9-Jun-98, to lugnet.robotics.handyboard)

Justin Here is the file. Please feel free to modify/improve. I'm a doctor not a programmer, and I better keep my day job. Notice it borrows Randy Sargent's and Dr. Richard F.

| | clock signal needed for decoder chip
|
|
Hello, I am hooking some HP decoder chips to the handyboard. They are HCTL-2020's and they decode a motor position encoder signal. My problem is that I need to hook one of the pins on the 2020 (the CLK pin) to a clock. I'd like to get ahold of the E (...) (26 years ago, 8-Jun-98, to lugnet.robotics.handyboard)

| | Re: handshaking
|
|
(...) Regarding your earlier message, if you're just wanting to talk to a GPS, then you don't need handshaking, because I haven't found one yet that supports it. It is a simple three-wire interface to most GPS's, TX/RX and Ground. They don't support (...) (26 years ago, 8-Jun-98, to lugnet.robotics.handyboard)

All pcodes shipped with IC 3.1/3.2 are designed to work fine either with or without LCD. Prior to 3.1, you have to build a pcode specially to disable the LCD. -- Randy (...) (26 years ago, 8-Jun-98, to lugnet.robotics.handyboard)

Hello, I've been trying to compile .asm files using as11.exe. The files I received with my copy of IC contain the #include directive. Does anyone know of a copy of as11.exe that supports this?

Justin, Interfacing a GPS to the handyboard is straight forward. Most GPS receivers comply with the National Marine Electronics Association (NMEA) standards.

| | DC motors vs. servo motors
|
|
The nature of the PWM (pulse width modulation) is entirely different for servo's vs. plain DC motors. For a DC motor, it has a two wire connection. All drive power is supplied over these two wires -- think of a light bulb. When you turn on a DC (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)

| | Re: motors
|
|
For servo, there is a certain threshold duty cycle (say 50%) of the PWM signal, where anything above this threshold will make it to run forward, and less will make it to run backward. So, you still need to apply the PWM even if the servo is not (...) (26 years ago, 6-Jun-98, to lugnet.robotics.handyboard)
