I got mine from FutureActive. I don't remember what the cost was and I don't remember what else I got from them, but it was more than just that. I think I placed about 2 orders with them. I would much rather deal with Mouser and Digikey. If you have (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)

I found the driver you sent earlier. Thanks. BTW, I found out that my LCD is good but I still have a problem. It appears that I cannot change my CONFIG reg. Maybe because it is an 811E2; don't know. Should be able to however. Since the program was (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)

Wierd: Anyway I have some kind of problem with the handyboard. All steps up to the testing of the LCD went fine. When I plugged in the LCD and turned it on, it lights up (one line) bright not dim.

So, this still doesn't help me figure out how to address the LCD. It has A8 and A9 connected along with a CLK from Port A. Does this mean that the LCD is NOT memory mapped? Do I first have to write to Port B then write to Port A, to clock it. This (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)

Hi, does anyone know how fast should a micromouse move? and the other question is, will the 6811/handyboard have enough capability (address space) for maze solving? If not, what should I need? extra memory or 32bits processor? Thank you for any (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)

(...) Within limits, the rate doesn't matter much. What matters is the ratio of off time to on time (i.e., the duty cycle). Probably, you could change the frequency by an order of magnitude either way and get about the same results. --Will , , __@_/ (...) (26 years ago, 4-May-98, to lugnet.robotics.handyboard)

(...) You can only run the LCD when in single chip mode. (...) This leaves the chip in 'special test mode' that lets you go into and out of expanded mode by writing the config register. --Chuck (26 years ago, 4-May-98, to lugnet.robotics.handyboard)
