Description: VolumeMeter (Managed DirectX)
This project is a live volume meter control for monitoring audio levels from a sound card. It is written entirely in C#, and uses Microsoft s Managed DirectX (June release). You can drag-and-drop the control into any Windows Forms application. You may select the input, and tweak the appearance of the animation through various parameters.
The idea behind this project is to maintain a very short buffer of audio and constantly record into it. The control is on a timer, and periodically queries the buffer to see what volume level the most recent sample has, and then sets a progress bar s value accordingly. Platform: |

Description: 项目需求：
数字电视整转过程中，需要对多台同时进行授权操作的机顶盒的频道搜索、授权、机卡绑定操作进行监看。如果采用多台显示器进行监看比较麻烦，使用视音频切换器来进行切换观看的话，布线简单，节省时间。因此需要对切换器编程控制，减少操作的复杂度。
项目实现：利国1*8视音频切换器一台 编程工具为C++Builder。
-Project requirements: switch to digital TV the whole process, at the same time the need for multiple set-top box to authorize the operation of the channel search, the authorization card operations to monitor binding. If using multiple monitors to watch too much trouble to switch the use of video and audio to watch, then switch, wiring is simple, save time. Therefore need to switch programming control, reduce operating complexity. Project realization: Dr Q 1* 8 video and audio switch a programming tool for C++ Builder. Platform: |

Description: AVR ATtinyX5播放sd 卡 上的WAV文件。-This is a simple SD audio player biult with only an 8-pin microcontroller. The ATtinyX5 series (25/45/85) 8-pin AVR microcontroller has two fast PWM outputs in 250kHz carrier frequency. This enables to output a wide frequency range audio signal. I built an audio player with the 8-pin AVR and an SD memory card (SDC). The SDC can be controled with only six lines, two for power supply and four for control signals. It can also be easily attached to 8-pin microcontrollers. The main application of the tiny X5 series AVR seems SMPS and related according to its integrated peripherals.
Anyway this audio player is very simple and a few wires to be solderd so that it is suitable for brief soldering work before breakfast. There is an another project based on this project. Platform: |
