USB audio interface based on PCM2912A

Overview

Functionality:
A USB Type-C digital headphone jack that outputs a headphone signal via a 3.5mm headphone jack. The PCB board has a built-in MEMS microphone for recording.

Usage Scenarios:
Mobile phones, computers, and any Type-C

device. Principle:
The PCM2912A is a USB digital audio source interface that converts USB audio signals to analog signals. It supports both upstream and downstream signals.

Implementation of MSP430F5438A interrupt system
1. MSP430F5438A has three timers: TA0, TA1 and TB0. 2. CCR0 has a separate interrupt vector with the highest priority. Other CCR1--CCR5 share a common interrupt vector. 33. Interrupt vector: #define T
I want to learn computing hardware development, anyone who knows about it can come in and take a look
It is computer CPU development and memory development. I learned how to study transistors to store data, how to store digital signals, and how memory sticks use electricity to store data, etc. What ki
High pass filter circuit to filter sound
I built a high-pass filter circuit,as shownThe overall interface is that the computer's external speaker is connected to the input of the filter circuit, and then the output of the filter circuit is d
How to adjust the position of the soft keyboard on the taskbar in the simulator to any position on the desktop on the wince6.0 platform?
In the wince6.0 interface, how can I adjust the position of the soft keyboard on the taskbar in the generated simulator interface to any position on the desktop? Thank you!
AM3359 serial communication UARTGetChar debugging problem
[align=left][color=#000]I just started to learn how to use the AM3359IDK board. I tried to combine the routines i2c_led and uart_echo in the SYS/BIOS installation package to control the corresponding
This semester's electronics course designed an alarm clock made with G2452
The circuit is very simple. The long one is the carpet button, which is used to turn off the alarm. It can be stuffed into the carpet, so that you can sit down to turn off the alarm in the morning:lol
