TinyDuino Processors & TinyShields / Re: Pwm capabilities

In my ignorance, i mixed up the decimal on metric prefixes, but i am still curious what the available frequency range is on the tinyduino, or TS+. And if it's capable of running hpwm, in addition to other code at the same time

TinyDuino Processors & TinyShields / Pwm capabilities

« on: August 08, 2016, 08:51:20 AM »

Hey everyone, i have a prior project that needs a brain. I'm looking around for options to output a very reliable pwm signal. Everything i have read so far indicates i want a hardware pwm signal.

As far as frequency, i need something able to go from hz to at least 2khz. Faster would be most ideal. Up to maybe 30khz

I do also need a solid 3 pwm outputs, and another 3 more. I have been looking at a couple picaxe for this option, but I'd nees at least 2 for all the inputs and outputs id need.

What exactly is the tiny capable of in terms of pwm output? I noticed the  new tinyscreen+ has its own processor board thats capable of 32Mhz? But the tinyduino is only capable of 20Mhz? Is it possible to add an oscillator to generate a faster signal, or should i find something else to generate signal.

Little more about the project;
3 pwm outputs into either a high power transistor that pulses power into a laser driver. Or directly into an enable pin on driver
1 pwm for a pelteir
1 pwm for a 12v fan
1 on/off (ttl?) for a pump
Current read
Voltage read with led indicator array
A screen to show duty cycle on pwm
At least 3 Buttons, or pots to scroll menus/adjust duty and pwm
