Labs

Lab 1: intro to the PyBoard. Handout
Lab 2: music day. Handout and 2_pyboard_music_day.py
Lab 3: sEMG on an oscilloscope. Prequel lecture on real-time systems. Then handout, 3_scope_ECG_DAC.py, 3_scope_sEMG_DAC.py and adc_samples.py. Then a lecture on the music-day code (with a bit of basic Python if needed)
Lab 4: analyzing an sEMG on the host PC. Prequel lecture on filtering, a handout and 4_emg_process_host.py
Lab 5a: sEMG flashing LEDs on a PyBoard. Handout and 5a_emg_process_pyboard.py
Lab 5b: continuation. Handout and 5b_emg_process_pyboard_3chan.py
Lab 6: taking an electrocardiogram (ECG). Handout
Lab 7: analyzing an ECG on the host PC. Handout and 7_ecg_host.py

General resources for the labs

First, the all-important legal and safety overviews.
Turn in your homework on the web with at this link. It will ask you for you Halligan username and password; these are just your usual Halligan ones that you use for the Windows PC lab (not your Tufts UTLN).
How to build the breadboard
How to hook up the electrodes to your body. to read your ECG and surface-EMG. Also, 3M has published a nice website with more info, which also shows standard locations for an ECG (we won't quite use those locations, though).
How to reset/unwedge a PyBoard
How to use our oscilloscopes, with 2_scope_ECG_DAC.py and 2_scope_sEMG_DAC.py
How to run code from two different files on a PyBoard

Python videos and slides

The slides/videos for some of our labs have just-the-very-basics Python intro in them. If you want to go beyond that, here are some videos and slides to help you learn Python.

You don't need to install Thonny on your laptop, but you can if you want to. And here's more info on how to use it

Variables and expressions

functions

Arrays
- basic arrays
- The Green-Tea-Press book doesn't cover arrays at all (they're not focused on speed or memory efficiency).
'If' statements
- if-then
- Think Python, Chapter 5 (Conditionals)
Loops
