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)
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)
