In microstrip circuits, due to the high operating frequency, the analysis and design methods are different from those of lumped parameter circuits. Here we mainly discuss the design ideas and methods ...
I need to use the second CAN with the STM32 105 chip. The library function version I use is V2.0.2. Because the library function does not support two CAN channels, I copied the CAN part of the 3.0.0 l...
I have recently been working on a USB flash drive filter driver, which is overloaded below the disk driver and is a lower-level filter driver. Now I want to interact with the application layer, so I a...
I have been experimenting with RTC these days, but I often find that the values in BKP are inexplicably lost. I have a few questions and understandings about these. I hope the moderator can confirm th...
