Hello all.... I am currently trying to implement some level of shaft encoding/motor control on the handy board. I am using the shaft encoder software available on the H board site. I am currently using the "slow" version, as the top velocity reading (...) (25 years ago, 20-May-99, to lugnet.robotics.handyboard)

Guten Tag (hello in german) Yes, i think the book is a good way to learn a lot about robots. The software in the book is properly to use with the HB. I´m using the HB-Board too - and it makes a lot of fun ! Tschau and greetings from germany Bernd (...) (25 years ago, 20-May-99, to lugnet.robotics.handyboard)

I modified the sencoder() routines to work with quad encoders and a direction decoding IC. the encoder_counts now returns the correct count. I removed the velocity variable from the routine as well. I think I changed encoder routines 2 and 4 and (...) (25 years ago, 20-May-99, to lugnet.robotics.handyboard)

Konnichiwa !! I am currently using the shaft encoder drivers of handy and it works fine, until I implemented a PID (Position Control). I need to check the direction of my mobot. Which means that - if it goes backward, I need to decrease the count (...) (25 years ago, 20-May-99, to lugnet.robotics.handyboard)

Dear Robert, There is a file icmain.pdf which gives detailed information about IC. It should be available at the MIT site. Also html pages at the MIT sites should be containing the same information. The data given is specific to IC only and not to (...) (25 years ago, 19-May-99, to lugnet.robotics.handyboard)

HI, I just have a few questions for the experts, approximately how many lines of code can the handyboards memory hold? I want to know so I have a scope of how big a program can be written to it. Also I read in the mobile robotics book that it is (...) (25 years ago, 18-May-99, to lugnet.robotics.handyboard)

(...) Scott, any 2x16 character display with the 1x14 pinout will work, although the display may end up oriented the wrong way. ie. away from the HB (if you see what I mean). The hitachi chip is a standard interface, but some of the displays have a (...) (25 years ago, 18-May-99, to lugnet.robotics.handyboard)

I agree with Gary Livick, the best way to learn is by doing. My first program on the handyboard just displayed a message on the screen. My second program was to plug a couple of different resistors into the analog ports and print out the different (...) (25 years ago, 17-May-99, to lugnet.robotics.handyboard)
