This topic mainly introduces how to transplant the Linux operating system on arm, including bootloader, upper-layer application development, etc., how to build a Linux development environment, and the selection of arm chips, etc.
Recently, when dealing with some engineering problems, I am confused by some statements about capacitors. Can anyone accurately explain the three terms: stray capacitance, parasitic capacitance, and d
I added the #include "sipapi.h" file to the EVC project, and added coredll.lib to the "Object/Module Library". When I called SipShowIM(SIPF_ON); in the program to call the soft keyboard, an error occu
According to the forum, I swapped the R and T jumpers. I can occasionally receive data. But more importantly! ! ! ! I connected an external MAX232 serial port module and can receive data very stably.
Why is the capacitance of DC12V (C1) so large?
Is it larger than the 24V and 32V capacitors below?
Is it necessary to choose such a large size? What is its function?
