Title: 1~2ms pwm?
Post by: Stephanie on August 18, 2009, 07:51:28 PM

Okay, I got my Sabertooth 2x5 with the R/C signal mode (simulated by an Axon MCU).

But I can't find how to PWM 1~2ms! All I see is a servo command that uses "cycles" as an argument. How many cycles = 1 ms? Can I use a function that uses ms as an argument?

Thanks.

I can definitely explain how but it may be easier for you to use Webbot's Library.  If you want me to elaborate on how to manipulate the registers in the atmega640 to create the pwm signal let me know, and I'll post how.

Oh... I thought it would be a single function with port and pulse width.

Thanks, I'll just use Webbot's library then.
