Week14: Interface and application programming

Assignment:
- write an application that interfaces with an input &/or output device that you made
- compare as many tool options as possible

Part of my final project.

As a scientist/engineer I mostly use Python (with the spyder IDE of Anaconda). My goal for this assignement is to writte a Python script that:

Monitors a serial USB (coming from a MCU)
Send instruction through serial USB?
Do "real time" plot of the serial data

I'll use the PYserial library for the serial com, following this exemple.
I am on Windows 10 and I use Spyder through the Anaconda package. To install PYserial , i write conda install pyserial in the Anaconda consol (open with administrator right):

For the data management & display i'll use the numpy and matplotlib libraries. An interesting discussion here on how-best-to-do real time ploting with those tools.

My MCU pcb runs this code. It measures my sensor PCB with I2C and print the temperatures through USB Serial:

My Python script:

reads the serial
extract the temperature and time from the char line
save it in a numpy array
plot it live in a figure
