1. This is a discrete convolution algorithm. Since digital images are represented in the form of discrete pixels, the essence of digital image processing is the processing of discrete numbers.2. The s...
I have read some posts online saying that priority grouping must be set when using STM32 interrupts. Recently, when I was looking at other people's code, I found that the grouping was not set, but the...
We know that when FreeRTOS is delayed and blocked, task switching will occur, looking for a higher priority task to execute, or executing an idle task. So in FreeRTOS, if the current task is blocked b...
