Tiva TM4C1294 AND TIVA TM4C123 for the MCU on our boards

Hi Kevin,
My name is David Hodge co owner of Acme Game Designs.
We have contracted a software engineer to write code for our games.
We use Tiva TM4C1294 AND TIVA TM4C123 for the MCU on our boards.
We have as many as 30 MCUs in a given game.
The production quantity for each game will be around 3-5 k units so we will be using many MCU"s
We are using FREE RTOS and Coda Composer to develop the code.
Here is the problem.
We have 7 games designed but no code thus far.
I should not say no code but we have two problems that we must get passed in order to move forward.
We are having a roadblock with CAN and I2C.
First though we must get past the CAN issues.
We really need some help here to get moving as so much is riding on this.
We can send you Schematics as well as code examples.
Even though this is proprietary we would not mid posting examples as well as schematics here to help others and hopefully answer questions they might have.
All of the boards communicate via CAN so CAN is critical for our distributed systems.
Thank you
David Hodge
