On the modern stage of computing, programming languages are like dancers, while compilers are the choreographers guiding them from behind the scenes. Every piece of code written is like a carefully designed dance. On this stage, C language and GCC (GNU Compiler Collection) are a classic duo. Together, they perform a magnificent dance of compilation, … Read more

Teacher Zhu, this tutorial is based on notes I整理ed from a recent competition. I remember that there was very little information online about the KEA128 application in smart car competitions. I have graduated but couldn’t bear to delete these materials. If you think this article might be useful for everyone (especially those just starting with … Read more
Previously, I used the RT1052 development board, but now STM32 is obviously more popular among everyone. Therefore, I am providing this C file for everyone to benefit from the driver I wrote earlier. #include "bsp_lpspi.h" SPI_HandleTypeDef SpiHandle; void Spi_delay(uint32_t count){ volatile uint32_t i = 0; for (i = 0; i < count; ++i) { __asm("NOP"); … Read more

Introduction I have been researching IO for a long time and have been unable to connect bio and block device drivers. I only knew that bio is passed to the block device driver through the IO scheduling algorithm, but I never fully understood how this happens or where the IO scheduling algorithm plays its role. … Read more
