[font=宋体]I want to use AT89C51 microcontroller to control the actuators of a mirror frame scanner. There are five actuators. L298 is used to drive two micro DC motors and ULN2803 is used to drive thre...
IOPC4---WP; IOPC3---SDA; IOPC2---SCL; I adapted this from Liu Heping's book, and I feel there are mistakes in his book too! The following is to send only the data 0X05, and then read the data, but the...
I heard that the board has been sent out, but I haven't received it yet. I guess I can get it tomorrow. It doesn't matter. I've been busy with other things recently, and the preparation for PSoC4 has ...
[font=微软雅黑]The string DAC, sometimes called a Kelvin divider or Kelvin-Varley divider (named after its inventor), is one of the most straightforward approaches to DAC design. The simplest string DAC i...
When searching, if you enter the wrong keyword, or you think the keyword is not good after taking a look at the results, you have to wait 10 seconds after slightly changing it. If you don’t find the r...
I have just come into contact with PCI9656 (working in C mode). I have never been exposed to drivers before, so I also use the 9054 driver (I checked the registers and they don't need to be changed). ...
