As competition in the microprocessor market intensifies, the RISC-V instruction set has garnered increasing attention. Although RISC-V is not the first open-source Instruction Set Architecture (ISA), it is the first ISA that allows flexible selection of instruction sets based on actual application scenarios. The RISC-V architecture can accommodate all application scenarios, from high-performance server CPUs … Read more
C language is a computer programming language. It has characteristics of both high-level languages and assembly languages. As a system design language, it can be used to write system application programs, and it can also be used as an application programming language to write applications that do not depend on computer hardware. Therefore, its application … Read more

We have a product that requires LED lights to flash in sync. The area controller (in an STM32 microcontroller environment) sends wireless signals based on GPS signals to control the start time of the light flashes, achieving synchronization. A colleague implemented a function to send wireless signals, similar to the following: int RS232_lora_sendAlignInfo(void){ uint8_t send_buf[] … Read more
