I bought a keyboard matrix part, and I want to use AVR microcontroller to write scanning software, and HID to send via USB, so that this keyboard can be used like a standard keyboard, mainly to achiev...
Sometimes we need to implement the ISP function ourselves for the following special reasons. For ISP, ST has a lot of information, but most of it is in English, and we often cannot understand it. Let'...
[table=98%] [tr][td]I am currently using the LPC1768 chip. When downloading a program, all the I/O ports are forced to be pulled high, causing some circuits to run automatically when copying the progr...
I am working on a project recently and need to use the ZTE MC2716 3g module, but I know nothing about it. I don't know how to write a driver using a microcontroller. I only know that it has a PCI inte...
[color=#000]I used filterpro desktop to design a low pass filter circuit. There was no problem in simulation, using 1hz input. [/color] [color=#000]But after I soldered the circuit, I felt that there ...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
When the WDP500-2A plane grating monochromator is used to test the emission wavelength of a high-power laser diode at different currents, the matching of the laser diode has the disadvantages of lo...[Details]
Google's driverless technology is not only an eye-catching technology, but also a subversion of the car usage model.
