STM32 OneWire for Charger

Preface The current customer requirement involves touching the codebase, requiring assistance in developing 1-wire sensing for the battery, etc. We will go through UART OneWire to verify if it can function properly. There will also be some differences in the next version planning. Here, I’ll integrate and detail the OneWire information for verification methods. Overview […]

ECDSA_SignVerify(SHA256) STM32F4 series

Preface For the signature verification part, due to recent customer requirements, the MCU is bound and cannot be incorporated into SBSFU for updates. Additionally, the SBSFU update example currently only provides UART, and coding for other interfaces is required. After discussing with the customer, it was decided to use signature verification to ensure that the

STM32 Cryptographic Software Package

Preface The customer requires encryption protection for certain devices. ST offers two options: Directory Structure of V4 vs. Directory Structure of V3 The directory structure of the V3 software package corresponds to a separate directory for each STM32 series. The directory structure of V4 is fully compatible with the Cube/X-Cube software package (STM32CubeXX / X-Cube-XXX)

Discovery STM32H750XB-External Loader

Preface Due to the limited support for Flash models in STM32CubeProgrammer, only a partial range of MCU and Flash models can be covered, which cannot fully meet the customer’s needs. Therefore, an external Flash loader can be created using stm32CubeMX. Customers can customize the generation according to their own models. Here, Discovery STM32H750XB is used

Internal Temperature Sensor On STM32

Preface The STM32 microcontroller has an internal temperature sensor. The sensor is very rough (±1.5 °C) and is connected internally to one of the ADC channels, making it possible to easily obtain device temperature without the need for any additional components. However, please note that this temperature is a relative temperature, not an absolute temperature,
