For the audio speakers that everyone is familiar with, we can find such a phenomenon:
1. For bass, a large-diameter paper cone is generally used, which is not very elastic.
2. Mid-range: generally mad...
I want to use batteries to power the circuit board, but considering the working time, the capacity of one battery is not enough, and there are many hidden dangers when multiple batteries are connected...
Recently, the project needs to use Gaoyun FPGA to generate 720P HDMI data. I have tested 640*480 before and it is normal. Because 720p needs to use a 74.25MHz pixel clock, Gaoyun's DVI-TX IP core also...
I use GetHostByAddr to get the host name through the IP address, but it often fails to get the host name successfully. Occasionally, the host name obtained is localhost. When an error occurs, the retu...
I use TMS320DM368 for video compression. After burning UBL and UBOOT with JTAG, I found that the chip was unstable and often crashed. Later, I guessed that it was a DDR problem because the development...
