Just because the voice board-JQ8900N button triggers the voice module

Overview

In order to keep the appearance and appearance consistent, I specially drew a board frame similar to that of my brother, and the pad arrangement also adopted some characteristics.

Okay, let’s talk about the project now:
JQ8900N is a chip with integrated MP3 playback and IO port triggering. The operating current is about 12mA. The module adds a TP4056 charging module, and the charging current is set to 900mA. Be careful not to exceed the upper limit of the charging current when selecting the battery.

Instructions for use: 1. Connect the single-cell lithium battery to BAT+ and BAT-, and turn the switch to ON2. Connect the 8 ohm speaker to spk+ and spk- (no polarity restrictions) 3. Connect the USB to the computer, and the U disk connection will be displayed. It needs to be formatted for one use, the format is FAT4. Change the name of your favorite MP3 file to 00001.mp3 and put it into the USB flash drive. 5. Unplug the USB, off&on switch. 6. Each time IO1 and GND are shorted, the speaker will automatically Play MP3 files in U disk 7. If the file name is 00002.MP3, shorting IO2 and GND will trigger playback, and so on.

The influence of msp430 ADC sampling and holding time on sampling accuracy
The chip msp430fr5994 uses ADC for data acquisition. I found that the data obtained by defining different sampling and holding times are a bit different. For example, when collecting a signal of about
