## RASPberry pi ********************************ONLY RESPOND IF YOU CAN DO THIS**********************************888888

I need help with the SPi protocol of the raspberry pi

I need the code to send 2 bytes using the pins of SPi on Raspberry pi.

This has to be  a digital to digital protocol meaning for instance.

I want to send followint two bytes

11111111 00000000

********************************ONLY RESPOND IF YOU CAN DO THIS**********************************888888

I should be able to send them and the recieving slave would be able to pick this digital data.

## Electrical Safety

I need someone to answer the attached paper. Very simple terms I need definitions for them. NOTE: each definition should be briefly cited (from where did you get the definition). No Wikipedia, only academic sources. USE NFPA 70E book and you can find all the term there. If you can't access the book use any other academic resources that are available online. Keep it simple and clear. I need this as soon as possible. Two days maximum. I am willing to pay
