|
|
HI Just wondering what kind of success anyone has had with piggy-backing the L293's. My HB came with the TI h-bridge chips and I wanted to know if I could use the same technique. I figure if two chips can be run in parallel, giving up to 2A for each (...) (28 years ago, 10-Jul-96, to lugnet.robotics.handyboard)

Hi, I was wondering if there is a way to position the cursor directly. Using IC's printf function works great, but I can't position the cursor exactly where I want it.

(...) The Handy is like the 6.270; both have dig out latches going to the motors. The RW drives the motor ctrl pins directly. A re-write of the system PWM routines could provide finer than 8 levels of control, even w/o needing HW timer lines. (...) (...) (28 years ago, 10-Jul-96, to lugnet.robotics.handyboard)

Hi I've just built my first HandyBoard (thanks for the great service Prabal), and have a few questions (that I can't find in the FAQ). What are the hardware-imposed software differences between the HandyBoard and the 6.270/Rug Warrior boards ? ie it (...) (28 years ago, 10-Jul-96, to lugnet.robotics.handyboard)

Oh well, I THOUGHT I was done with my H-Bridge.. It seems to be running a bit hot. I had originally tested the motors with a bench supply, and the current never exceeded five amps, so I thought the TIP 120/125 circuit was "just right". It now seems (...)
