In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
In simple terms, high-end chips solve many complex problems, mid-range chips solve a single complex problem, and low-end chips solve a simple problem. Let's learn more about the relevant content wi...[Details]
Regarding the PHY construction of LWIP, the PHY chip used is LAN8720A, RMII mode. Regarding the hardware connection part, the Atomic board F407 is used, and the hardware connection is as follows: ...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
