Calendar, syllabus and final projects

• The class calendar is here.
• The syllabus is here.
• If we decide to do final projects, you may choose any final project that you're interested in. Some potential choices are here.

Powerpoint slides for the lectures

• Unit 2: operating systems
• Unit 3: Cardiac electrophysiology
• Unit 4: DSP intro
• Unit 5: Languages
• Unit 6: Environments
• Unit 7: Wavelets

Labs general info

• First, the all-important legal and safety overviews, as well as the ECE department's standard safety information
• Turn in your lab reports on the web 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).
• Here's an overview of how to hook up the electrodes to your body to read your ECG. It unfortunately shows you the hookup for lead III (left leg to left arm) and for surface EMG, neither of which we use. 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).
• You can find the Disco kit schematic here, the reference manual here and the data sheet here.
• If you've not used an oscilloscope before, here's a reasonable tutorial from a different class (most of it is also applicable to us).

Common files for the labs

• Some common files that you'll need in multiple labs: lib_ee115.c, lib_ee115.h, ADC_DAC.h, ADC_DAC.c, LCD.c, LCD.h, UART.c, UART.h
• A clean project-setup environment for the VSCode/FreeRTOS labs (i.e., everything except for lab #1). Download it to Windows and unzip it, and you'll get an entire directory tree.

The individual labs

• Lab 1: prelab, Blinky disco on raw metal, main_lab1.c.
• Lab 2: prelab is chapter 3 of the FreeRTOS book; Blinky disco with FreeRTOS and lab2_main.c.
• Lab 3: prelab is this video; FreeRTOS debug derby, lab3_main_problem1.c and lab3_main_problem2.c and
• Lab 4: collecting your ECG; main_ECG_capture.c and ecg_normal_board_calm1_redone.c_data
• Lab 5: ECG filtering on a host and lab5_host_filtering.py, la_ra_warren1.csv
• Lab 6: prelab, ECG processing on the Disco kit, lab6_main.c and ecg_normal_board_calm1_redone.c_data
• Lab 7: prelab video, wavelets lab Google colab

Resources for learning about CSRs

• Chapter 14 describes GPIOs, which are the main way we talk through pins
• Chapter 21 describes D-to-A conversion. We use D-to-A and A-to-D conversion starting in lab 4
• Chapter 20 describes A-to-D conversion
• Chapter 22 describes serial communication, which is how UARTs work (as well as SPI and I2C, two common protocols)
• Chapter 11 describes interrupts, which is how the 1ms tick for FreeRTOS is implemented
• Chapter 15 describes timers. We don't use them, but other people do -- a lot.
