# SPI input to 5500 from a Microchip TC77?

## Question

Asked by Garbonzo on 2014-04-18 in Ethernet Chips.

Howdy. Cowboys and Cowgirls, and other Folks, I am working on my SPI input from a Microchip TC77, I would like to make this go into the 5500 since I need to measure the temperature on the chuck wagon. Not sure how yet? Any idea where this would go? And how to see it on the internet? Garbonzo want to win a CONTEST! Please help!

Thanks partner :mrgreen: , This is just a logic stream of data from the TC77, I dont have it plugged into the 5500 yet ![:confused:](https://emoji.discourse-cdn.com/twitter/confused.png?v=12) , not sure where the wires and data would go in the 5500? I know where the TC77 goes on the chuck wagon ![:unamused:](https://emoji.discourse-cdn.com/twitter/unamused.png?v=12) .

The first 13 bits of the 0x0D 0xD7 represent 0000110111010 or decimal 442 which is multiplied times the TC77 resolution of 0,0625 deg C so its reading 27.625 deg C here on the ranch today. But thats what I want to go into the 5500 so I can read it on my internet. does that clear up what Garbanzo is trying to do?
