MicroPython on Nucleo STM32, STM32F411CE, and STM32F401CC: flashing firmware and basic tools

Microcontrollers, the core of many embedded systems, have evolved from being programmed with low-level languages like Assembly or C to more accessible high-level languages like Python. MicroPython, a streamlined Python 3 implementation, is a prime example. This article explores the integration of MicroPython with the cost-effective, high-potential STM32F4 microcontroller from STMicroelectronics, with a focus on the WeAct STM32F411CE, STM32F401CC, and Nucleo board.

STM32 Power saving: STM32F4 black-pill manages clock and frequencies – 2

An essential factor of our micro-controllers is power consumption. As usual, I started to analyze that aspect without entering the detail for sleep mode but with some alternative solutions offered by the micro controller.
Now we are going to examine the management of clock frequencies of STM32F4 series.

Mastering clock source and frequency management is vital in STM32 development. The STM32F1, or “Blue Pill,” provides several options to balance device performance and power saving. The STM32F1 sources its clock from an internal RC oscillator (HSI), an external crystal oscillator (HSE), or a Phase Locked Loop (PLL) that can amplify the HSI or HSE for higher frequencies. By carefully choosing and setting up these clock sources, you can greatly optimize your device’s power consumption.

STM32: add SPI flash memory with FAT FS

The first SMT32 prototype boards don’t have an embedded SPI Flash, but the latest, like the WeAct STM32F4 board, has a footprint to add It. And for me, It’s very useful. The only problem Is that this Core doesn’t have a native library, so we will use the Adafruit one.
