STM32 power saving: wake up from RTC alarm and Serial – 6
As usual our microcontrollers give a wide range of wake up sources, we already see a timed wake-up, and now we introduce the wake-up via RTC alarm and Serial of our STM32.

I will explain how to use the STM32, 32-bit microcontrollers based on the Arm® Cortex®-M processor.
STM32 power saving: sleep, deep sleep, shutdown, and power consumption – 5
We have already described Idle mode and the relative power consumption, in this article we continue to measure power consumption of other sleep modes to have a brief comparison.
STM32 power saving: library LowPower, wiring, and Idle mode – 4
In a remote device, one important feature can be the power consumption, and like other devices, STM32 allows a set of Low Power states.
In this article, we look at the library to use and performance with our devices.
STM32 power saving: intro and Arduino vs STM framework – 3
In a remote device, one important feature can be the power consumption, and like other devices, STM32 allows a set of Low Power states.
In the Arduino framework, these states are wrapped and simplified to allow the most straightforward management, but we will look at the original state of STM32 to better understand the test results.
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.
STM32 power saving: STM32F1 blue-pill manages clock and frequencies – 1
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.
Unleashing IoT Potential: Integrating STM32F4 Black-Pill with EByte LoRa E32, E22, and E220 Shield
The STM32F4 Black-Pill, a powerful and versatile microcontroller, offers promising potential for IoT applications when integrated with LoRa modules like EByte’s E32, E22, and E220. In this article, we’ll examine the Shield I use for rapid prototyping that supports all the LoRa modules described.
Unleashing IoT Potential: Integrating STM32F1 Blue-Pill with EByte LoRa E32, E22, and E220 Shields
The Internet of Things (IoT) landscape is evolving at a rapid pace, leading to an increased demand for robust and scalable communication technologies. LoRa, or Long Range, is one such technology that has gained significant traction in recent years. In this article, we will delve into the integration of STM32F1 Blue-Pill, a highly capable microcontroller, with EByte LoRa E32, E22, and E220 shield modules, which are popular for long-range, low-power applications.
I start using STM32 microcontrollers, and I find they are of superior quality. But I need a prototyping board to do my work faster.
STM32: internal RTC, clock and battery backup (VBAT)
In this article, we will delve into the inner workings of the STM32’s internal RTC and its associated clock system. We will also discuss the importance and implementation of battery backup (VBAT) in ensuring the accurate and uninterrupted operation of the RTC. Whether you’re a seasoned engineer or a beginner looking to broaden your knowledge, this article aims to provide you with an in-depth understanding of these key STM32 features, allowing you to unlock the full potential of your embedded systems.
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.
