My initial idea is to use an AT89S51 chip, add A/D conversion and D/A conversion, add an amplifier and a speaker, and a digital display. But I don't know how to do the voice recorder part. I would lik...
This issue mainly describes the use of stm32GPIO, and makes a GPIO example (flowing light). You can download it in the attachment if you need it.The test on Smurf stm32 passed....
My new computer arrived today. When I bought it, there were 512+1T hard drives and 512 only hard drives. Since I have a lot of hard drives and I plan to install them myself, I didn't choose the one wi...
The TI development board onboard emulator is very convenient. What I want to ask is whether the CPLD can be removed, because I still need to program the CPLD, which is very troublesome. Please answer ...
For PCB failure, we need to use some common failure analysis techniques to ensure the quality and reliability of PCB during manufacturing. For this purpose, the author summarizes ten techniques for PC...
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]
