A 1” by 1” 20msps Oscilloscope based on the PIC32MZ For the Return of the Square Inch Project, we are designing a PIC32MZ based oscilloscope that is only 1” by 1” including an OLED screen.

This project is designed around a PIC32MZ EF processor. We use its internal ADCs in an interleaved mode in order to get the full 20Msps. We have found that in practice we are able to achieve approximately 1MHz of bandwidth.”
