NeoSPI

A simplistic C++ SPI NeoPixel driver that works on any linux device with SPI

• build:

make

• run:

./example/NeoSPI_Standarttest /dev/spidev0.0

• clean:

make clean

• Troubleshooting
  • If you are using a Raspberry Pi 4 or similar you need to inhibit the downclocking of the CPU otherwise the LEDs will be white
  • If your LEDs aren't RGB LEDs but they are a different order or they have an additional white component then they wont work with this library but if you open an issue I will try to implement them (I haven't implemented them because I don't own any)
  • If you see any flickering or lower brightness than expected then please check your powersupply before opening a issue
  • If the LEDs are currupted check that the spidev on your device is 6.4MHz for the 800KHz neopixels or 3.2MHz for the 400KHz models
• If you want to drive more than 170 LEDs it is necesary to increase the SPI buffer size using spidev.bufsiz=65536 in the kernel command line
