This library enables you to use Interrupt from Hardware Timers on an STM32F/L/H/G/WB/MP1-based board. These STM32F/L/H/G/WB/MP1 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's mandatory if you need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.

STM32 based DC-DC converter
A mini-oscilloscope, written in Rust, for the STM32F3 Discovery microcontroller board.
My ring/FIFO buffer implementation, for embedde applications. Tested on STM32L1, STM32F3, STM32F4 and PIC18F platforms.
The FlashStorage_STM32F1 library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory of STM32F1/F3. It's using the buffered read and write to minimize the access to Flash. It now supports writing and reading the whole object, not just byte-and-byte. New STM32 core v2.0.0 is supported now. Useful if the EEPROM is not available or too small. Currently, STM32F1/F3 are supported.
