RetroPie With WaveShare 3.5inch RPi LCD(A)
RetroPie image + WaveShare LCD 3.5(A)
reboot後檢查
那/dev/fb1就是3.5LCD了
編譯fbcp
就可以了
如果買的是3.2b 把上面35a都改成32b即可
git抓下只有這兩款 , 如果是4吋的不知道能不能用
完成後ssh連不進去 , 應該是輸出的問題 . 我沒研究 ...
官網的驅動

裡面的方法對RetroPie的image會有rpi-update出現ca的錯誤裝不起來

Thanks for the clear tutorial. Did you manage to have a good framerate with this screen. I'm trying but cannot find the right configuration (even with speed=4000000)
Bye
