RP2350

RP2350 sample code file

Some RP2350 files

Using MicroPython and PIO on Rapsberry Pi Pico 2 (RP2350) in order to implement some interfaces (via PIO), e.g.:

• MDIO
• BSTI
• QSPI
• SPI

File:

• RP2350_SPI.py : a regular SPI peripheral for SPI master
• RP2350_PIO_SPI.py : a SPI master via PIO
• RP2350_PIO_MDIO.py : a MDIO interface (bi-directional DIO) with PIO and DIR signal (for level shifter)
• RP2350_PIO_BSTI.py : similar to MDIO but separated DIN and DOUT (no DIR signal needed)
• RP2350_PIO_QSPI.py : a QSPI master with 4 bi-directional lanes, DIR signal
• other files for testing GPIO, LED

Boards:

These scripts are tested and used on:

• SparkFun Pro Micro - RP2350
• Pimoroni Pico Plus 2 (with RP2350)

FPGA as level shifter

Using a Trenz GmbH FPGA board, TE0725-04-72I-1-B as level shifter board and for HW extensions. Find the FPGA files in the sub-directory (for AMD/Xilinx Vivado 2023.2, an Artix 7 FPGA used as bi-directional level shifter, which needs a DIR signal to do so, therefore my bi-directional interfaces on RP2350 provide a DIR signal)
