树莓派的系统是安装在 SD 存储卡上的,所以在需要准备好,里面有重要资料的话提前备份转移。 我这里是以 Raspberry Pi Zero 2 W 为例,因为其性能有限,所以会安装不带图形界面的 Lite 版本系统。官方文档推荐该版本系统使用 4GB 以上容量的 SD 卡,不过为了方便后续在里面放置电影等显示素材,我更推荐 16GB 以上的...

CPU use is not of concern for Rasbperry Pi 2 or 3 (as we run on a dedicated core anyway) but proably for Raspberry Pi 1 or Pi Zero. Default: no dithering; if you have a Pi 3 and struggle with low frame-rate due to high multiplexing panels (1:16 or 1:32) or long chains, ...
If you need to change the GPIO pins for any reason, see tftgl/src/tftgl_ssd1963.h The pinout is set to Raspberry Pi Zero, which should be compatible with A+, B+, and Pi2 as well. Please refer to image: https://www.element14.com/community/servlet/JiveServlet/previewBody/80667-102...
--led-slowdown-gpio=<0..2>: Slowdown GPIO. Needed for faster Pis and/or slower panels (Default: 1). The Raspberry Pi 2 and 3 are putting out data too fast for almost all LED panels I have seen. In this case, you want to slow down writing to GPIO. Zero for this parameter means...

needs to be ran on each panel individually first before you push any data to them, I then ran some demos using the sudo ./led-image-viewer image.png –led-rows=32 –led-cols=64 –led-chain=2 works great also you can use the –led-pixel-mapper=U to use 2 panels as one 64x64 ...
Other boards are very similar, but instead of zero-indexed color bits R0, G0, B0, R1, G1, B1, they start the index with one and name these R1, G1, B1, R2, G2, B2; the functionality is identical. Throughout this document, we will use the one-index base, so we will call ...
