 | | MAX232 Chip
|
| To all: I am constructing my first Handy board. I am currently building the interface board, but have hit a small 'snag'. While performing 'step 2', installing capacitors and MAX232, and then testing, I did not recieve the correct voltage outputs. (...) (26 years ago, 24-Feb-99, to lugnet.robotics.handyboard)
| | | | | Re: External Motor Power and the Expansion board.
|
| ahah, good question. the exp bd grabs the 9v motor power for the servos, sonar, and 9v lego sensors. if you're not using any of these, you could leave connector off the exp bd and you'll have no probs. if these are important, you need to reconnect (...)

|
| The modulation frequency of the IR diodes must match the sensor (depending on exact part number, around 38 KHz) within +/- 3 KHz. As you move away from the center frequency, detection drops off sharply. Are you able to confirm the modulation (...) (26 years ago, 23-Feb-99, to lugnet.robotics.handyboard)
| | | | | ICC11v5 - interrupts
|
| I have a HB (running under IC3.2) that is linked to a 'slave' TCOMP board (68HC11E1, 32k ram) which is programmed using ICC11v5. I need a function similar to 'msleep' on the TCOMP unit. I am trying to use portions of Chuck McManis' HB library for (...) (26 years ago, 23-Feb-99, to lugnet.robotics.handyboard)
