| | Re: Creating multiple serial outputs with the HB expansion board
|

Have you considered (not sure about the full requirements) but designing a secondary expansion board with serial controllers instead of the expansion headers?? Just an idea, but the Motorola version of the serial processor (6850?) should be a good (...) (26 years ago, 11-Mar-99, to lugnet.robotics.handyboard)

| | Creating multiple serial outputs with the HB expansion board
|
|
I would like to create multiple serial outputs (like 3 or 4) using the digital outputs on the handyboard expansion board. The purpose is to drive an external servo controller and external motor controllers (motorminds) which can handle more load (...) (26 years ago, 11-Mar-99, to lugnet.robotics.handyboard)

Ja, a laptop would work. Even better, cheaper, why not use a good old desktop coputer? Then you could just have the components you need, IE a motherboard, a removeable video card, sound card, the amount of memory you like, etc. Best of all, the (...)

I had the same problem. I tried everything, even replacing the CMOS memory chip, to no avail. Since my board was purchased assembled from Gleason, I ultimately swapped them for a replacement which has been working perfectly. I don't know whether (...)
