Trivia 1: Cost saving phenomenon 1: It doesn’t matter what value these pull-up/pull-down resistors have, just choose an integer of 5K. Comment: There is no 5K resistance value on the market. The close...
(10ppm error means 0.8 seconds error per day) If the error is found to reach 1 second per day when using a single-chip microcomputer as an electronic clock, how can the software be used to reduce this...
Question: The microcontroller receives data from the PC parallel port. For example, AT89C52 does not have a parallel port interrupt like a serial port interrupt. Can I handle it like this? 1: Connect ...
Recently I want to use dshow to make a video player on ce 5.0, but it seems that PB does not provide several files such as strmbase.lib of the simulator, and I don’t know how to compile it. If any exp...
The project I am working on now is about DM8168 and C6678 communicating through PCIe. The current situation is that the DM8168 translates the address of the data to be processed in its DDR to the PCIe...
