DMA transfer draw graphics and ULP music player Sample
-
DMA転送で画面描画するサンプルとULPで音楽再生するサンプルを合わせてみた。
DMA転送の合間にdelay(2)入れて1フレームあたり30msecのdelayを実行しているけども問題なく約30fpsで描画と音楽再生してる。
音はかなりノイジー…もうちょっと何とかする方法ないかしら…Video: https://m5stack.oss-cn-shenzhen.aliyuncs.com/video/Blog/Twitch201904/DMA_transfer_ULP_music_player.mp4
