STM32_UART_Examples

STM32WB55Cx_minimal

(Currently untested) minimal STM32WB board. These look cool because they have a bluetooth / 802.15.4 radio and an internal switching power supply. Fun!

SQLite3_STM32_SDMMC

Repository to test building sqlite3 as a static library for an ARM Cortex-M platform. Nothing functional yet, but I plan to use the 'Gristle' FAT filesystem library with a custom SD/MMC peripheral driver for the STM32L4 line of microcontrollers. Why? Because I want to make a handheld GPS mapping device, and it'd be cool to use spatialite databases.

STM32_quickstart

Another 'quickstart' recipe for starting a new STM32-based GCC project. I've tried a few different project layouts for bare-metal C applications targeting Cortex-M microcontrollers, and this repository is an effort to reduce the common pain points that I encounter by minimizing external dependencies and auto-generating tedious compenets like the vector table.
