The update interrupt initialization configuration of the stm32 advanced timer TIM1 is not much different from that of the ordinary timer. What needs to be paid attention to is the configuration of TI...[Details]
After searching a lot of information, I finally understood the time base timer. I did not use any library functions but operated the registers directly. The following introduces the systick in STM32...[Details]
1. About FPU transplantation As long as the chip has FPU function, the use of FPU is generally enabled by default. You can also select it in the Options tab; 2. About the transplantation of DSP li...[Details]
The goal of this article is to build a TCP client based on the previous project that can ping the PC, and can actively send data to the PC, and can also send and receive data with the PC, and display...[Details]
This program mainly uses the comparison output function of the timer to generate PWM waves to control the LED. The comparison output of timer A corresponds to P2.3 P2.4. Therefore, a matching working...[Details]
1. FSMC Brief FSMC, the Flexible Static Storage Controller, is capable of interfacing with synchronous or asynchronous memories and 16-bit PC memory cards. The FSMC interface of STM32 s...[Details]

Ouster LiDAR OS-1 (left) and OS-2 (center) Velodyne invented the modern 3D LiDAR scanner in the mid-2000s, but in recent years conventional wisdom has held that Velodyne’s design — 64 lasers mounted...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
ADC: 1. The ADC module inside STM32 has three ADC1, ADC2, and ADC3, which are independent of each other, so synchronous sampling can be performed. 2ADC input clock must not exceed 14MHz, it is genera...[Details]
