I ported lwip 1.2 on uCos, and the udp and tcp server sides can run normally. However, when used as a tcp client, that is, when actively connecting to the server, let lwip run first, and don't open th...
STC's 89C52RC microcontroller uses the serial debugging assistant software as the sender, and sends a string in the format of "888 777 666" (separated by spaces) in ASCII mode. The problem is that aft...
I see that all development versions have 64M sdram. My hardware is 32M. I never noticed this problem before. Now I am confused. Can you tell me more? Thank you....
I am currently working on a project using the 32f103 series, and it is already running. However, a problem occurred during the operation. Specifically, there is a compressor on the periphery, and the ...
My understanding is that the conduction process of the triode goes through the cut-off region-amplification region-saturation region. Why is the image in the book cut-off region-saturation region-ampl...
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]
