Hi, Willem! Sorry, but "sonar_library_1.0.zip" is not full: "sonar.c" not found! And how about Devantech CMPS01 Compass library? It need i2c in HB. Do you plan this? ===...=== Best regards, Andrew. ----- Original Message ----- From: "Willem van (...) (22 years ago, 4-Jan-02, to lugnet.robotics.handyboard)

Jan, On ribon cable the lead that has the marking is simply there to make it easier to tell what lead is what on the other end. The marked lead usually denotes pin one, but not always. Remember that the drawing is show from a bottom view. Pin 9 is + (...) (22 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

I don't think this is quite it -- IC sets the byte if there's a main fcn. It also sets up some code so that main fcn gets run. Fred (...) (22 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

John, I think it lies in the Pcode, in other words if the pcode sets the 0x8000 to 1 then any program loaded that has main() in it will auto run at startup. If the pcode does NOT set 0x8000 to 1 then no matter what you have loaded as a program it (...) (22 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

Dan, Perhaps I'm misinterpreting what you mean by "a startup program". To me, a "startup program" means there is a file downloaded to the HB that contains a " main() " function, i.e., a function which will automatically be executed upon startup (...)

Hi, Without a 0.1 µF capacitor, your sonar won't work correctly. I don't know why. Martin (22 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

Hi, I bought a Polaroid 6500 for x-mas and now I’ve got two questions: 1) In the Handy Board Interfacing Diagram of the Polaroid 6500 at the Handyboard page V+ is connected to the pin 9 of the Polaroid 9-pin connector. But the flat cable to the pin (...) (22 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

John, I just did the same test, I think what Fred was saying is that IC sets the 0x8000 to accept a startup program if one is loaded. If I poke a 0 to that address then load any program it sets back to 1. I think he was wandering if your IC version (...) (22 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

Matt, The only mod I've made to my HB is to cut the motor power supply "+" trace and use a separate motor power supply. See my post/response to Dan for my explanation of that.

Dan, Yes, I did cut the trace for external motor power. I know the HB and the motor power "+" sources are isolated because I not only checked with a VOM, but I removed the motor supply batteries and when I run my motor test program (remember, no (...)
