 | | How to add more IC lines?
|
| Hi, all It appears that the proposed expansion board will not have any additional input capture functions. I've run out of Input Capture lines on the Handyboard, so does anyone have a suggestion on which processor could best be slaved to the (...) (28 years ago, 8-Aug-96, to lugnet.robotics.handyboard)

| (...) Did you tried to remove the resistor? I actually simply fitted the IR diode in the female header. I found that the red diode beside the header would light less if the IR diode is emitting, since those two diode are installed in parallel. The (...)

| Also... For Tx I use a high power IR LED with about a 5-10ohm resistor (I can't remember exactly) Because the carrier is 50% duty and the signal is not continuous, this is ok. If you use a lower powered IR LED and/or a higher resistor, you may find (...) (28 years ago, 8-Aug-96, to lugnet.robotics.handyboard)

| Jeff, You are right. Several things could be wrong here. First of all the precision resistor is VERY VERY important. This controls the frequency of the carrier signal. The freq is approx 1/(RC) where R = R4 and C = C6 of the the Handyboard IR Tx (...) (28 years ago, 8-Aug-96, to lugnet.robotics.handyboard)

| (...) A partial solution which I found is effective in turning a tracked platform on carpet, is to run the pivot tread in the same direction as the turn tread but at a much slower rate. This worked quite well with a Radio Shack Sherman Tank, but the (...) (28 years ago, 8-Aug-96, to lugnet.robotics.handyboard)
