Introduction to APM32F4 Flash Simulating EEPROM 

EEPROM, often used for data preservation during power outages, is not inherently available in APM32F4xx MCU. In order to cut costs and avoid using an external EEPROM chip, this video will share two methods on how to simulate EEPROM functionality using the internal Flash of APM32F4xx MCU. The main content includes an introduction to the principles, analysis of challenging points, and implementation of the code.
