- merge with original master from jorgen - minimize RAM usage of all components - use both IRAM and DRAM in player component so we can buffer up to 1s on modules without SPI RAM - support fragemented pcm chunks so we can use all available RAM if there isn't a big enough block available but still enough HEAP - reinclude all components from jorgen's master branch - add custom i2s driver to get a precise timing of initial sync - change wrong usage of esp_timer for latency measurement of snapcast protocol - add player component 2021-08-19 21:57:16 +02:00			`#ifndef _MERUSAUDIO_H_`

upgrade to IDF v5.1.1 custom board driver ma120x0 is broken esp dsp is now IDF managed component mdns is now IDF managed component Signed-off-by: Karl Osterseher <karli_o@gmx.at> 2024-01-08 22:49:11 +01:00			`#include <stdint.h>`
