Frequently Asked Questions
Common questions about STM32 and STM8 microcontrollers
The STM32 F3 series is based on the ARM Cortex-M4 core like the F4, but it's designed with mixed-signal capabilities. The F3 series has enhanced analog peripherals, including multiple 4MSPS ADCs with programmable gain amplifiers, making it ideal for applications requiring precise analog measurements. The F4 series focuses more on processing performance and connectivity options.
Migrating from STM8 to STM32 can be streamlined using ST's migration tools and documentation. For applications that were using STM8 for basic control tasks, the STM32G0 series is often a good starting point due to its value-oriented feature set. ST provides software libraries and migration guides that help transfer your code more efficiently.
STM32Cube is ST's ecosystem for software development that includes HAL (Hardware Abstraction Layer) libraries, middleware, and development tools. It simplifies development by providing pre-tested drivers, reducing portability issues between different STM32 series, and accelerating time-to-market. The ecosystem includes STM32CubeMX for pin configuration and STM32CubeIDE for development.
