We have an Arduino which is periodically transmitting pressure and temperature values over serial, and we need a raspberry Pi 2B+ to take that data in, parse it out from the communication protocol, and display the data on an attached 7" Pi touchscreen in a large and clear graphic that I will define. We'd like the Pi to do this automatically upon power-up without requiring a user to start any programs.
This is for a proof of concept prototype, so the exact details of how this all happens can be adapted with your input. But the hard criteria are: easy-to-read display on the 7" Pi screen of 4 pressures and 4 temperatures received over serial from one of the USB ports.
Please estimate total project cost. Message me with questions.
Payment upon delivery of functional program will be via credit card.
