Creating Network Transceiver using DVSwitch #3.Encoder and PTT installation (and Release Version 0.5)

Creating Network Transceiver using DVSwitch #3.Encoder and PTT installation  (DVPi Version 0.5 released and Rotary encoder, PTT installed) I added some hardware extensions in version 0.7. Also read the article at Link below. This post describes the additions made in Version 0.5 and the encoder and PTT installation.

Creating Network Transceiver using DVSwitch (or DVLink) #2-How to use

Creating Network Transceiver using DVSwitch (or DVLink) # 2.How to use I upgraded DVPi to Version 0.4 today. The download location is the same. The functionality has not changed. It just changed the default volume of the Raspberry Pi's speakers and microphone. (Speaker : 100%, Mic : 80%), Also, the button position of the Menu Screen has been changed slightly.

I want to make a simple Network Walkie Talkie using the Raspberry pi. After downloading the image, write it to the SD-Card and enter the server information in the ini file.  It's a simple task, but I wrote it step-by-step, making the article longer. If you have a Raspberry pi experience, you don't need to read this article in detail. I uploaded all the contents of this article in a video and uploaded it to YouTube. I'll link to the video at the end of this article.

I am planning a project using Raspberry Pi.

I have several types of Raspberry Pi boards. The Raspberry Pi board is probably one of the most sold boards in recent years. Raspberry Pi boards are inexpensive and have great performance. The best thing is that you can use Linux. The figure below is a collection of RPI V1 to V4.  It is RPI V1 The board on the right in the photo below is a recent RPI V4. Already, amateur radios are using a variety of Raspberry Pi boards. I am trying to make something new. For example, network radios for amateur radio, Devices using Wsjt-x I experimented with cheap USB sound cards for the new project. All are USB sound cards under $4. The sound quality was all poor. However, the RPI's fast CPU will enable DSP functionality. Below is a $2 USB sound card with a cable attached to it. All are compatible with RPI. Below, I thought it was possible to input a 2CH microphone with a $4 USB sound card. However, it was only 1CH microphone input. The first project
