This is a circuit I found online. The test distance is less than 10CM. How can I increase the distance? I added an NPN transistor to the DO, but it didn't work. I then replaced the receiving tube with
When I was working on the minimum FPGA system, when the crystal oscillator output pin was not connected to the FPGA's GCLK, the output amplitude was 2.78V at the maximum and 1.88V at the minimum. But
I am now using PLC + position module + stepper motor for control and found the following problems:
(FX2N-80MR PLC, FX2N-20GM position module, Shenzhen Reise stepper motor;)
1. The stepper motor will j
Want to make an LCD setting interface, and set the numbers bit by bit? I use a 12864 LCD without a font library. I want to set the value, for example, 123. First set the hundreds digit, select it, pre
This disassembly team really loves Tesla. I remember that some time ago, in order to see what is inside a Tesla battery, they actually disassembled a Model S battery:It's quite stupid, but I felt real
[b]With the advent of SoC design elements such as the MIPS32 1004K Coherent Processing System (CPS), on-chip symmetric multiprocessing (SMP) with a single operating system has become a real design cho
