MP3 alarm clock using Huimang microcontroller

Overview

Set the alarm clock to wake up the MP3 player and automatically go to sleep after 10 minutes of playback. The sleep current is uA level. I feel that this chip is not bad.
Lao Wang’s small square box player (the chip was disassembled, the MP3 is placed in the SPI Flash, although it is compressed a bit, But the effect is pretty good)
If you need a program, please add me Q

1. Method of creating waveform diagram by timing simulation in ModelSim
If you need to perform timing simulation in a higher version of QuartusII, you usually need to call ModelSim for simulation, but creating waveform files is a bit cumbersome. Below are examples and ste
