Schematic review

Expert 2065 points

Hello

I have finshed our schematic and as we are a bit new to TIVA C, I woudl like someone to give us comment and review our schematic before we move forward to routing the board.

I would apprecite if people who have a bit some experience with this chip could spend a few minutes reviewing our schematic against potential mistake.

Thank you very much for your time.

Regards

Hi,

A small observation: for the master, you need a termination resistor, or a split termination as related in this document. Also on the last slave on the bus.

Hello,
Function are going to key tactile switch and two Jack 3.5mm plug whhich we will use as connector for tactile switch on wire.
For decoupling capacitor I need indication about which capacitor will need to be close to which pin as it was not mentionned in the refernece design.
