Electronics Design

This week, our group used the Digital Multimeter(DMM) and Digital Oscilloscope to observe the operation of a circuit board with SAMD11C.

Group Assignment

  • [✓] Use the test equipment to observe the operation of a microcontroller circuit board
  • Documented by Darren Chan

Equipments

INNOVA 3320 DMM

  • AC/DC Voltage Measurement
  • Resistance Measurement
  • Diode Test
  • Continuity Test
  • AC/DC Current Measurement
  • Battery Test

LabNation SmartScope

  • 2 Oscilloscope channels @ 100MS/s sample rate
  • 8CH Logic Analyzer
  • 1CH Analog + 4CH Digital Wave Generator
  • App Platform: Windows, Linux, OS X, Android, iOS

Results

We tested Darren‘s IO board, hello.servo.D11C and a USB-TTL adapter. We checked:

  • the input voltage of the USB
  • the regulated voltage of the IO board
  • the voltage delivered to the P02 when the button being pressed and released
  • the waveform of the LED when it’s blinking
  • the waveform of the LED when it’s fading
  • the encoded signal when a usb-ttl adapter
