Yeah, that was easy,\u00a0 I just gather resources here as reference…<\/p>\n

Next I want to daisy chain a few of these, and then I’ll get into the real stuff: Getting my 8×8 RGB led array connected and working, this time no ready module.<\/p>\n

\n5 Electrolytic capacitor 10uF 1
\n6. 0.1uF ceramic capacitor 1
\n7. 10K resistance 1
\n8. 8P hole seat 2 (2.54mm pitch)
\n9. 3mm 8*8 Yin red dot matrix 1<\/p>\n

Connect:
\nVCC: 5V
\nGND
\nDIN: MOSI (GPIO10)
\nCS: SPI CS0 (GPIO8)
\nCLK: SPI CLK (GPIO11)<\/p>\n

Get Python libs and check out test.py:
\ngit clone https:\/\/github.com\/rm-hull\/max7219.git
\ncd max7219\/
\nsudo python setup.py install
\nsudo python examples\/test.py<\/p>\n
