Jeff Epler 8e69092434 reduce post_addr_delay 
The original post_addr_delay (the delay after changing the ABCD(E)
address lines) was pretty long, for two reasons: First, the initial
timing numbers were chosen conservatively without regard to
performance; and second, because they were originally chosen
assuming a high PIO clock rate but we lowered the PIO clock to
2.7MHz.

Together this made the delay a huge 185us!

The new value of 5 is about 1.8us instead; this gives a nice
increase in FPS from 88 to 120 on my 128x128 (4 lane, 6/2 plane)
setup, without any visible artifacts.

RGB Matrix Panels With Raspberry Pi 5

Installation

Installing from source:

  • clone this repository
  • pip install ./Adafruit_Blinka_Raspberry_Pi5_Piomatter

Installing from pip:

  • pip install Adafruit-Blinka-Raspberry-Pi5-Piomatter

System setup

If ls -l /dev/pio0 reports that the file is not found, you may need to update your Pi 5 firmware to one with PIO support and make sure that you are running a suitably recent kernel. If ls -l /dev/pio0 reports that the file is owned by root and group root, you should add the following to /etc/udev/rules.d/99-com.rules:

SUBSYSTEM=="*-pio", GROUP="gpio", MODE="0660"

Building the documentation

Documentation for the example project is generated using Sphinx. Sphinx has the ability to automatically inspect the signatures and documentation strings in the extension module to generate beautiful documentation in a variety formats. The following command generates HTML-based reference documentation; for other formats please refer to the Sphinx manual:

  • cd Adafruit_Blinka_Raspberry_Pi5_Piomatter/docs
  • make html
