[毕设] 如何优化你的屏幕帧数 [嵌入式] [ESP32-S3-N16R8] [VScode+PlatformIO]

[env:esp32s3]

; ESP 32 6.6.0 use Arduino Framework 2.0.14, TFT_eSPI 2.5.43 library can work normally

; Higher Arduino Framework version will cause compatibility issue: Guru Meditation Error

; More details: https://github.com/Bodmer/TFT_eSPI/issues/3329

; Solution: https://blog.csdn.net/qq_42757207/article/details/139062034
