Introduction To achieve better development speed and future iterations and portability of products, layered frameworks are essential. However, strictly adhering to these principles for small to medium-sized projects can consume excessive energy in system design, which is a decision-making process. 1. What is Layered Framework? In embedded architecture, it is generally divided into hardware architecture … Read more
Hello everyone, I am a newly hired embedded engineer. Like many friends who are just starting out, I feel both excited and a bit anxious in the vast ocean of technology: how can I transform the theories from books into the ability to solve real problems? My answer is – to get hands-on with a … Read more
Using USART to send strings with STM32: The meaning of the code is: When there is data on the receive pin, the status register USART_FLAG_RXNE will be set to 1. At this point, the return value of USART_GetFlagStatus(USART1, USART_FLAG_RXNE) will be 1 (SET), and if there is no data, it will be RESET. Common code … Read more

1. Introduction A bootloader is a critical program responsible for booting and updating embedded devices. In automotive ECUs, during OTA upgrades, the bootloader is responsible for downloading, verifying, and writing new firmware, ensuring that in case of an anomaly, it can revert to the old version to guarantee driving safety. Mobile system updates rely on … Read more
DWT is a debugging peripheral, and one of its core functions is CYCCNT, which is a 32-bit incrementing counter used to record the number of clock cycles executed by the CPU. We can achieve rewriting the HAL_Delay function or implement microsecond-level delays by monitoring the changes in this counter. Appendix: 1. Source Code dwt.delay.h file … Read more
