STM32 Snippets are collections of highly optimized code examples using CMSIS compliant direct register accesses to reduce the code overhead allowing to maximize the performance of the STM32 MCUs in various applications.
The more than 100 Snippets per STM32 Series demonstrate efficient use of the STM32 peripherals with the smallest possible memory footprint.
Example:
