I'm stumped. In the process of assembling my first handyboard, I have just reached the stage where I install the memory (all previous checkpoints passed).

My handyboard is experiencing some kind of a -POWER-GLITCH-. At least that's what is displayed just before the board shuts itself off. How did this happen, and what can I do about it? Thanks in advance. Avard Fairbanks (28 years ago, 26-Jan-97, to lugnet.robotics.handyboard)

(...) There are a number of ways to do this in C. If you get the code that comes with the Handyboard, they have msleep(500L); which sleeps for 500 milliseconds (L for LONG Integer) and then returns to the calling program. My code is at work, but I'm (...) (28 years ago, 26-Jan-97, to lugnet.robotics.handyboard)

The 8MHz crystal is no longer listed in the Mouser Catalog (part #332-5080). When I look in the DigiKey catalog, it lists several 8 Mhz crystals with different load capacitances (18pF, 20pF, 32pF, and Series). Does it matter which I get? If so, (...)

Hi Wade, You can use the "seconds()" function which reports elapsed time, plus a variable to keep track of when the loop should end: void main() { float end_time; end_time= seconds() + 20.; /* go for 20 seconds */ while (seconds() < end_time) { /* (...)
