 | | sending signals over power lines
|
| hello. While this question doesn't pertain directly to the handyboard, I thought I would post it here since I am using the handyboard in my project. Some of you may have heard of this product: There are devices on the market (radio shack and a few (...) (28 years ago, 27-Dec-96, to lugnet.robotics.handyboard)

| I can hardly contain my glee! After 3 weeks of fun-yet-obsessive, marriage-threatening, Xmas-be-damned behavior, I've got all four IC and OC interrupts going, receiving/processing/outputting 4 RC PWM signals. This is only a side-note for Handyboard (...) (28 years ago, 27-Dec-96, to lugnet.robotics.handyboard)

I never managed to change it with hbdl, and now I only use IC (...) (28 years ago, 3-Feb-97, to lugnet.robotics.handyboard)

I guess I was drawing too much current. Anyway I am (...) (28 years ago, 6-Feb-97, to lugnet.robotics.handyboard)
