Logic and protocol analyzers

Module goal: capture digital signals and decode protocols to prove what is really happening on the wire.

Status alpha (in trial use) · about 130 minutes

You need: a logic analyzer that works with PulseView, and a TESAIoT Dev Kit flashed with the QWA309 Header I/O Test example

Lesson	Topic	Time
elec.m04.l01	Capturing your first digital signal	65 minutes
elec.m04.l02	Decoding I2C and UART	65 minutes

Module checkpoint

• can capture a blinking signal on a header pin and measure its pulse width and frequency
• can fully decode an I2C bus scan, including address and ACK, and compare it against what the screen shows
• can decode UART at 115200 baud and explain the symptom of setting the wrong baud rate
