Roadmap / Hardware
Test & Debug Instruments
Your eyes for voltages and signals you cannot see. Half of debugging is measurement.
Goal Check circuits and signals with instruments and narrow down a fault.
- 01Multimeter
Voltage, current, resistance and continuity, and common mistakes when measuring current.
- 02Oscilloscope3D lab
Trigger, timebase, probe compensation. Reading a circuit from its waveform.
- 03Logic analyzer
Decoding UART, SPI and I2C to see the traffic itself.
- 04Bench supply and electronic load
Current limit to protect a board, and a load to test the power stage.
- 05Debugger
Flashing and single-stepping firmware with ST-LINK or J-Link.
- 06Soldering and rework
SMD soldering, flux, and hot air for removing and fitting parts.
Read one UART byte as a waveform
Capture a UART signal with a logic analyser or oscilloscope, read the bits yourself and calculate the baud rate.
