Seeking best microchip

Hello,

I am working on a prototype and need a chip fast that can emit two pulse width modulated signals, and run a timer at the same time. The prototype needs to be able to send pulse width signals on two different outputs

    How fast does the PWM have to be?

    If it's something that is going into production, the cheapest and easiest solution would probably be a small PIC, like the new PIC16F1826 - it's got some amazing capabilities. If it's a one-off, you might be better off with a Propeller.

    Right now its a one off, the model is more for exhibition. Ideally it would be a freq of 225 hertz with a microcontroller update speed of around 10 ms. I was already leaning towards the prop chip just gotta learn the spin language. Thanks!

    would it be possible to accomplish this with a javelin?

    The Propeller is your best bet. There are objects in the Object Exchange that can do the PWM and a timer is easy. Details depend on your particular situation.
