Oscilloscope, logic analyzer and CAN debugging

Not started

Self-directed study

Using bench instruments to debug signals and serial buses.

Practice in the Flight Lab: Read the I2C capture · UART framing and a SPI chip select · Probe the edge · Who went bus-off · Silent sensor

Subareas

Scope triggering, probing & groundingRise time, ringing, noiseLogic analyzer protocol decode (UART/SPI/I2C)CAN frames, arbitration, error frames, terminationpython-can scripting

What to learn

Capture and decode UART/I2C
Inject and diagnose CAN errors
Script CAN logging in Python
