Greetings All, Have purchased a new computer and cannot communicate with my handy board. I remember some time back in the mail archives that some settings had to be changed if the computer was too fast for IC but cannot find it now. Computer has a (...)

(...) The obvious question is how you are measuring your capacitor and resistor values?. Resistors (presumably metal film), are typically +/-1%, but capacitors are unlikely to be 'better' than +/-5%, and may be significantly worse than this (many (...)

| | Re: 41Khz not 38KHz
|

The 3.81K resistor is probably more accurate than its rated 1%, but the capacitor may be much less precise, unless you got a tight tolerance metal film one, (as I think the part list specifies). Precision also relies on the thresholds of the Schmitt (...) (25 years ago, 12-Feb-00, to lugnet.robotics.handyboard)

Maybe somebody could help. I am try to use the IR output. the problem is that the HB is modulating the signal at 41kHz and I need to get it down to 38kHz. I have checked the resistor and capacitor used in generating the frequency. R = 3.81 K C = (...) (25 years ago, 12-Feb-00, to lugnet.robotics.handyboard)
