Example - UART Blink
A small example to demonstrate the UART capabilities between the Arty Z7-20 Zynq PS and the STM32G030 MCU located under: /UART_Blink_Example/
- FPGA: Sends a UART message periodically to the STM32
- STM32: Receives the UART message and toggles the LED
- "LED1" blinks when receiving UART messages from the FPGA
- "LED2" blinks as a heartbeat of the STM32
Setup
- Connect the PMOD board to the FPGA
- Flash the STM32 example via the SWD pins
- Program the FPGA and run the example in Vitis
The FPGA needs to have the UART enabled and the uart_tx pin routed to the PMOD connector pin 3.
Example - UART OLED
Another example to display incoming UART messages from the FPGA to a small OLED display connected to the PMOD board.
Setup
Same as UART Blink

Questions
How big is the STM32-PMOD PCB?
It measures 62.5 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32-PMOD use?
18 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the STM32-PMOD KiCad files?
From the MxMueller99/STM32-PMOD repository on GitHub, at the commit this page was made from: the board is KiCad_files/STM32_PMOD.kicad_pcb and its schematic KiCad_files/STM32_PMOD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32-PMOD design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
