Re: [PSUBS-MAILIST] Re: Motor controller...
Hi all,
I've been silent for a while on this list... If you
need to build a pcb based on your schematic I can help
you. I have all the software tools to do it.
I'm already working on a controller (using a PC and
microcontrollers on a RS422/485 serial port interface)
to measure all the parameters in a sub in different
points (temperature, pressions, current in the motors,
O2 level, tilt, speed, depth...)and control the
valves.
I'll be very happy to help you if you need a digital
interface between your joystick and the analog circuit
you already built (PWM with a duty cycle proportional
to the joystick position).
