The system tick timer is a peripheral that exists in all m3 cores, but the number of other timers in m3 cores is different. Therefore, the system tick timer is generally used as the system time base, which is also convenient for the transplantation of RTOS in different chips. 1. Configure tick timer On the graphic page of cubemx, you ...

1, Mapping from linux physical address to virtual address linux cannot directly operate the physical address. If you need to operate the hardware, you need to convert the physical address into a virtual address first. Because linux enables MMU, you cannot directly operate the physical address. 1. What are the benefits of enabling MMU? (1) Make ...

1. Introduction to G4 series DMA First, introduce the DMA of G4 series. Although the G4 series of 32 is based on the M4 kernel, its DMA channel mapping is quite different from the common F407. First, paste some pictures in the reference manual: I don't know what you can think of after seeing these two pictures. I believe friends who have see ...
