I know this is the Handy Board mailing list...but we are still using 6.270 boards in my course, and I recently finished porting Julian Skidmore's Smooth Pulse-Width Modulation (SPWM) motor routines over to the 6.270 board. This software upgrade (...) (25 years ago, 24-Jan-00, to lugnet.robotics.handyboard)

The location(C7) for the .1uF that you are refering to is located on the sonar driver board, on the lower left corner of the ribbon connector. Any non-polarized cap will do just fine. (...) (25 years ago, 24-Jan-00, to lugnet.robotics.handyboard)

An optical sensor with a filter in front of it. Standard photocell works fine. Three of them, each with a red, green, and blue filter and then sampling the three inputs can be very flexible. --Chuck (...) (25 years ago, 23-Jan-00, to lugnet.robotics.handyboard)

|

(URL) sells a relatively cheap camera/frame grabber package named the ramcam. you access it directly and treat it like a ram chip. The color vision would proboly be easy to interface as a color sensor. And To you Handyboarders out there, would this (...) (25 years ago, 23-Jan-00, to lugnet.robotics.handyboard)

(...) I would imagine that this is the case since Fred states on his page that it won't work without it on most versions of the driver board. The easiest way to do it is just desolder the two pads that align with the c7 position on the HB. Stick a (...) (25 years ago, 23-Jan-00, to lugnet.robotics.handyboard)

In my reading of it, it will just chew the cycles. Here is the routine msleep(), used to implement sleep. See how it just does a busy wait? I wrote a version (now gone into data heaven when my drive crashed) that would check the time, and then give (...) (25 years ago, 22-Jan-00, to lugnet.robotics.handyboard)

How clever is the multitasking in IC? If I have a task that I only want to run ever 10 seconds, can I just put a sleep statement at the top of the routine? Will the sleep statement chew up processor cycles, or will IC realize that it should defer to (...) (25 years ago, 22-Jan-00, to lugnet.robotics.handyboard)
