Hi to everyone, I just got my Handy Board Kit and going through the very first step of the assembly i found the first problem. In the handy board assembly instructions it describes capacitors C15 and C16 as 4.7uF Tantalum capacitors but in my kit (...) (29 years ago, 17-Jul-96, to lugnet.robotics.handyboard)

The FAQ has information on sending and receiving info thru the serial port. My Question is: How do I do the other end in C. This is what I got the computer side of the serial cable: port = open("/dev/ttyS3",O_RDWD); <- THis is from my head, not (...) (29 years ago, 16-Jul-96, to lugnet.robotics.handyboard)

Dirk, Without actually seeing your icb function, it would be hard to determine exactly what is going on. But here are some guesses: 1) When you are modifying control registers in MC, make sure that you use bit commands so that you don't set or erase (...)

Thanks to Joeo for the hints on caputuring data from the handyboard. I have another question: Why does my sony infrared system stop working after calling a function which I have defined in an icb file? I have a number of functions defined in that (...)

I'm using a hall effect sensor as a shaft encoder. 8 magnets have been placed on a wheel of my bot, such that they turn the sensor on and off as they pass by. I have written a small program to test the encoder, which makes the robot go forward 10 (...) (29 years ago, 15-Jul-96, to lugnet.robotics.handyboard)

HI Check for a short between pin 11 of the 'hc374 and +5V. Pin 11 is supposed to be connected to pin 9 of the 'hc138. It is the select line for the 8 flip-flops in the 374. If you have a logic probe, check either of these pins. They should be (...) (29 years ago, 15-Jul-96, to lugnet.robotics.handyboard)

| | IC memory map

(...) Right now, IC reserves 16k for shared code and data space. 8k is for the multitasking stacks and interaction download space, and 8k is for pcode. -- Randy (29 years ago, 12-Jul-96, to lugnet.robotics.handyboard)

8K might be all that IC allows for user global data. The memory map can be rearranged, but only at the compile-time of the IC application. Newton Labs should be able to give you a definitive answer about the memory organization of IC 3.1. -Fred In (...) (29 years ago, 12-Jul-96, to lugnet.robotics.handyboard)
