I originally planned to use 2013 to make 16-bit AD, and then use SPI to transmit the data to 149. When I was doing it, I found that there were too few materials for 2013, especially Chinese materials....
As a transmission technology based on ordinary telephone twisted pair, ADSL is highly dependent on physical transmission lines. The characteristics of the loop will have a decisive impact on the quali...
Both of my machines have 100M network cards. I used a test software to test the network speed, and it can reach 26 Mbps, which is still far from 100 Mbps! Why is this? I use a direct-connect network c...
In order to further understand and use the SC8905 power control board, I carefully read the "SC8905 EVM User Guide" today and found that the description of the register settings for charging and disch...
