[Raspberry Pi 4B Review] + Environment Construction, OpenSSL Library Usage
Yesterday I got the long-awaited board, and today I started testing. First, I set up the environment. Various tutorials on th...
I need to design a dual DSP channel controller for work. The DSP uses TMS320F2812. If a fault occurs in channel A, it will automatically switch to channel B. I plan to use FPGA or CPLD to implement ch...
I want to buy a mobile power bank to power the development board, but the power interface on the development board is a round port, so I want to buy a USB to round port power cable, but I have never b...
I set P1DIR = 0x10; P1SEL = 0x10 in 430FW427; P1.4 port should output the system frequency, but when I measured it with an oscilloscope, there was no output. What's going on?...
Solution 1: Direct AC input, and constant current control for 6 LED strings
Among the solutions introduced in this article, this one should be the one with the highest efficiency and the lowest circui...
The technical leader of the company uses pads95, but I use altium designer. The company wants to unify the EDA tools, of course it is pads95. I have not found a good pads95 book or learning video, ple...
