Hello,
I'm considering an unusual embedded application which requires 250
simultaneous PWM outputs, all independent. I will poll digital
feedback values from each of the 250 devices (heaters) and use this
information to adjust the output duty cycles on a PID loop algorithm.
The chip would be dedicated to essentially this task only, with only a
handful of discrete I/O (start/stop signal & a couple of indicator
LED's).
Is there a single microcontroller that can do this? I looked at
Atmel, but there are so many possibilities and I'm afraid I'll waste
money on a development kit for a specific processor and then find out
that there was something better, cheaper, easier to learn, or more
appropriate.
Thanks for any leads you can provide.
