My name is Larry Cicchinelli and I have been the Rabbit Tech Support Manager since 2001. My previous work experience was with Ford Motor Company for 33 years as a design engineer. Most of that time was designing and implementing automatic test equipment for automotive electronic devices.
This blog will be dedicated to describing the different projects we work as part our roles as engineers. My colleague, Puck Curtis, will have a companion blog describing his side of the process. (You can find his blog in the navigation menu on the right side of the blog.)
I love your site! I’ve been looking for just such a site since I want to build wifi roverbot and have been wondering what components to start with. I’m an EE (Michigan Ann Arbor). Are you in MI?
Anyhow just wanted to say I appreciate your site after all of 2 minutes.

Hi Dave, Glad you like the site! Please see Puck’s blog for more good stuff.
I lived in Allen Park for three years working for Visteon until I retired and took the job with Rabbit which was ZWorld at the time. I am now in Davis, CA.
Hi Larry
I have build some interesting camera systems for the film “The Cove” I have used Rabbit and Basic Stamp processors.
I’m currently working on a system to control a autonomous boat … Don’t ask ’cause I can’t tell you
and would like to use a Rabbit SBC.
So, I need the PWM output to control a standard RC servo as you describe in your Rover project. But I can only do the PWM_SPREAD to get the freq to quadruple, I have no idea how you are getting the 3 pulses “swallowed”. Also, when the PWM.c sample program is running the stdio window claims that the freq is 200hz, but my scope tells me 1,000hz ,
any advise appreciated,
perhaps a snippet of the arguments you use for pwm_set

Hi Simon,
Take a look at the PWM chapter in your processor manual. Locate the section that describes the PWLnR registers. You will see that bits 4 & 5 allow you to suppress X of Y pulses. You might also be interested in reading the article from Ask Larry. At the bottom of the article is a link to a sample program which help you.
OK I see it there,
