From the project

A versatile multi-protocol 1.8V/3.3V/5V logic signal generator.

A versatile multi-protocol 1.8V/3.3V/5V logic signal generator powered by a PIC18F25K50.

8 independant channels featuring several standard protocols. The microcontroller hardware I2C, UART, SPI and PWM modules are used to provide the signal timings. Entirely USB-powered, no need for an external power supply. Dedicated power supplies and ground connector to easily power the device under test. The embedded 1.8V and 3.3V power supplies are each able to provide 500mA (these power supplies are derived from the USB power, so the available power could be limited by the USB port).

Logic Signal Generator: common questions

What microcontroller does the Logic Signal Generator use?

The Logic Signal Generator is built around the PIC18F25K50-xSO, from the PIC family.

How big is the Logic Signal Generator PCB?

The Logic Signal Generator measures 70 × 60 mm, has 2 copper layers and is 1.579 mm thick.

How many components are on the Logic Signal Generator?

51 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Logic Signal Generator design files?

From the RICCIARDI-Adrien/Logic_Signal_Generator repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Logic Signal Generator design in my own project?

The repository has no license, so all rights stay with RICCIARDI-Adrien. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Logic Signal Generator without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
