Hi all,
Just came up with a devastating realization . My all-too-expensive LM629's , encoders steering setup will not work through the parallel port. The number or i/o lines to "talk" to the 629's aren't enough . I am just thinking aloud . Could I use an intermediate micro-controller to recieve commands from the PC ( 4 bits ), 16 commands are enough and then the micro-controller to output hex instructions for the 629 to understand . Since my position , vel,accn co-efficients are going to be constant ( the motor shaft moves through a fixed pos,at const vel,accn
[10 degrees , 500 rev/s and 0.1 rad/ s/s]
for every 1v change in the joystick pot) . Why then a PC ? for one - I can display a virtual steering and other input data such a joystick pos . But the important reason is that joystick inputs are read by the computer.
Any other suggestions on how this could be implemented
Thanks
