Hi all, a few reactions to Adam's multi-sonar schematic: * looks like a clever idea and it's an extremely clearly drawn schematic. I put a copy up at (URL) Adam, if you would ZIP up and e-mail me the code you use to drive this, along with any other (...) (28 years ago, 24-Mar-97, to lugnet.robotics.handyboard)

I am still having trouble with the my program and thought that I might ask whether there is any code or does anyone know of a way to identify the frequency of digital square waves with the handy board. Joe Martin joema@mpx.com.au (28 years ago, 24-Mar-97, to lugnet.robotics.handyboard)

Pandit, It turns out that we where both wrong about your program.It does not work because the time over which d adds 1 to itself is not defined the program does not count at a rate of one unit per millisecond.I have in fact found that it will at (...)

The LCD pins are just the databus, and some strobes. No power here, just information. And not much possibility for PWM either, since databus timing is constrained by the CPU bus timing. Best to hook something stuctured to the databus, ie the (...) (28 years ago, 23-Mar-97, to lugnet.robotics.handyboard)

What is it that you want to accomplish by doing this? Drive your motors? According to the CPU and Memory diagram, the LCD control lines come directly from the HC11 microprocessor. The voltage is generally about 5 or so, but the lines cannot output (...) (28 years ago, 23-Mar-97, to lugnet.robotics.handyboard)

HI! I had an Idea..... What would happen if I were to wire some motors to the LCD output (to screen)? But for me to really do that, I need a couple of things answered: 1) How many volts does it run at? 2)Did anyone ever try this? Advice? Thanks.... (...)

I have just recvd and read over the docs of my newly acquired Vector2X compass. I would greatly appreciate any assistance that an experienced user might have to offer. Although it looks as though the wiring overhead is minimal, I would like to (...) (28 years ago, 22-Mar-97, to lugnet.robotics.handyboard)

Peter, Are you familiar with C in general? I think if you put a static value in the [] of the array declaration and fix the increment of f (f+1) to f++ or f=f+1, then you'll be OK. Try it. ---...--- Adam B. Cox check out my web page Computer (...) (28 years ago, 22-Mar-97, to lugnet.robotics.handyboard)

Hi Joe, I kind of guess that this result will come up as I mentioned that I do not fully understand the intention of the program. I would suggest that you put sleep(onemilisec); in the time keeping process it self in side the while(1) loop for the (...) (28 years ago, 22-Mar-97, to lugnet.robotics.handyboard)
