Maker Mirko Pavleski has demonstrated tips on how to flip a Seeed Studio Wio Terminal right into a compact two-channel oscilloscope, “primarily meant for academic functions” however usable in a pinch for troubleshooting and extra.
“An oscilloscope is a extremely helpful digital check instrument used for visualizing and analyzing electrical indicators over time,” Pavleski explains of the undertaking. “It gives a graphical illustration {of electrical} waveforms, making it an important software for engineers, technicians, and scientists working with digital circuits and techniques. I’ll describe a easy approach to flip [the Wio Terminal] right into a small two-channel oscilloscope.”
Designed as an all-in-one microcontroller improvement platform, the Wio Terminal relies on an Microchip SAMD51 chip operating at 120MHz with 192kB of static RAM (SRAM) and 4MB of off-chip flash. To this, Seeed Studio has related a 2.4″ shade show, inertial measurement unit (IMU), microphone and buzzer, gentle sensor, infrared emitter, and a microSD slot for storage — plus three buttons and a five-way joystick for native interactions.
It is these which offer management for Pavleski’s oscilloscope undertaking, which relies on a firmware developed by the pseudonymous “Goji” and initially written for the Microchip PIC24 in 2014. Pavleski’s contribution to the undertaking is a housing which gives a straightforward approach to join units on check to the Wio Terminal whereas maintaining the cabling neat and tidy.

“[The] Wio Terminal ADC [analog to digital converter] is just not very quick,” Pavleski admits, “so this system has virtually no sensible use, however it’s due to this fact easy, cheap, and excellent for finding out the way in which the sort of instrument works, in addition to its adjustment particularly due to the extraordinarily professionally made graphic interface.”
