The F1-series has evolved over time by increasing CPU speed, size of internal memory, variety of peripherals. The STM32 F1-series was the first group of STM32 microcontrollers based on theĪRM Cortex-M3 core and considered their mainstream ARM microcontrollers.

↳ STM boards (Discovery, Eval, Nucleo.

↳ Let us know a bit about you and your projects.

infrared) bounces phase shifts and timing.īut normally that needs nanoseconds measurement speeds, so something may be missing or that it is a matter of knowhow. I think it is possibly even possible to implement 'time of flight' distance measurements measuring light (e.g. These boards are 'underutilised' in the sense that they make good / accurate daq devices such as logic analyzers low sample rates oscilloscopes etc olimex, adafruit etc publish schematics for their boards.įor stm32f401/f411, after setting boot0 it can actually use the usb dfu protocol to install firmware, that makes it more convenient as you won't need a separate serial dongle etc, simply set boot0 connect usb and flash awayĪ key feature is the use of external crystals in most stm32 boards, this gives you accurate clocks and makes it stable for usb comms

the (reversed) schematics can be found from various web searches. blue pill stm32f103c8 or better still stm32f401/f411 black pill or even nucleo boards and experiment with them. The easier way to get started is to get an existing board e.g.

Which tells you that to use the uart boot loader you would need to set the boot0 pin Those outline the basic hardware to use a stm32f103cxĪN2606 Application note STM32TM microcontroller system memory boot mode If you do some (google) search you would find app notes like thisĪN2586 Application note Getting started with STM32F10xxx hardware development Stm32f103cx can be programmed from the serial uart pins or swd pins
