Dual VNH5019 driver and Propeller Quickstart

Need some help here (Duane!)
A while back I got the Dual VNH5019 driver and have been tinkering with it on my BRP with an Arduino Mega... now I'm moving over to using Propeller Quickstart for my processor. There is a Dual PWM driver on the Obex Exchange, but I see now that the connections for the driver are not the same, the Dual VNH5019 board has 6 required I/O connections and the Obex Propeller driver (PWM2C H-Bridge Engine)only uses 4 I/O pins...

Also wondering if I need to run any resistors between the I/O's?

Trigonometry mostly, so that it can decide where to go next. Also avoids obstacles …

Hi all,

I have a arduino uno and a OV7670 + FIFO 422b camara module (22 pins). But I'm not sure how to connect those two and view a video stream on my computer using the serial port(that is my ultimate goal). Do you have any ideas/blog links that describs how to do that?

Why I Respect my Robot Elders

I've been forced to take holiday from work, Bek has closed my lab until June 1st, and I don't do down-time well.  Given I'm without a lab for the moment, I'm forced to seek other outlets for my brain.  So, I thought I'd write a few reflections regarding my experiences at LMR in the last two years I've been a member.

I thought I'd write about something I've noticed about LMR in regards to the influx of knowledge: Respect for our Robot Elders.

Wild Thumper Robot Controller: getting started autonomously

I'm a beginner in coding and I'm trying my best to work with the sample code, but now I've come to an impass. Can someone tell me what I'm doing wrong with this? http://pastebin.com/cFscTs6d 

I'm getting the error:

Wild_Thumper_Controller_Prototype.ino: In function 'void I2Cmode()':

Wild_Thumper_Controller_Prototype:357: error: a function-definition is not allowed here before '{' token
