Raspberry PI small program

Job ID: 31427118

Budget: $30 – $250 USD

Background: We are an electronic designer company, with hardware and C/C++ skills but no experience on Raspberry.
The project consists of creating a software that will run on a Raspberry PI, and teach us how to compile it, install it and make it running onto our Raspberry.
The source code must be provided. We would like the programming language is C / C++ and free of charge compiler / IDE


The software to create need to have theses functions:

1) collect a file at a fixed URL (csv text file, ~35 kbytes, we will provide the file and all the details)
2) Search 2 informations by city name (it's temperature values) inside the file, collect it as a string
3) compute a CRC of the string
4) send to the serial port the temperature string and the CRC
6) wait 10 minutes and start again at 1)

Notes: the serial port is hardware UART (TxD, RxD) on Raspberry's GPIO header, 9600 bps
Software can be GUI or console, at the condition that it is easy to maintain by us.

At the end of the project, we need to have our Raspberry PI running continuously in our lab.
