About The Project

TC Logger Device is a simple thermocouple USB reader: help you to measure any proccess you need using the USB protocol an a simple software developed in Python. The project was chosen to test the USB communication, explore the interface PC-Embedded system. The project is able to use two thermocouple at the same time and share the data to the computer at a speed of 5Hz. (5 samples per second). The main microprocessor is the PIC18F14K50.
