Prefer Many developers using STM32 to build USB Composite find that the official support only provides H503 CDC+HID. However, some customers require DFU+other, which we modify here based on external add-on packages. I-CUBE-USBD-Composite I-CUBE-USBD-Composite is an unofficial software package that helps us quickly build a template. Basically, it can be used by modifying certain components. […]

Preface EEPROM is a type of semiconductor storage device that can be repeatedly overwritten electronically. Compared to EPROM, EEPROM does not require ultraviolet light exposure or removal, and can be erased by applying a specific voltage to the chip in order to write new data. In this section, we will introduce the advantages and disadvantages

Preface Recently, a customer started researching STM32G031 Flash read and write. When the customer used the sample code provided by the official website to write to Flash and added a Timer interrupt, the system kept entering the HardFault_Handler(). I started researching the Flash status and the HardFault_Handler() checking program. HardFault_Handler Check Procedure First of all,

Preface We want to ensure that the program running before firmware update will not stop, so we need to implement the Dual Bank Flash feature. While downloading the updated firmware on one bank, the program will continue to run on the other bank. After completion, the firmware version will be compared, and the latest version
