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.
Category: STM32
The STM32 family of 32-bit microcontrollers is 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.
Ebyte LoRa E32 & MicroPython: specifications, overview and first use – 1
Ebyte LoRa E32 series are a collection of wireless transceiver modules. In this article series, we will explore the Ebyte LoRa E32 device and its integration with MicroPython. This first article will focus on the specifications and basic use of the device.
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.
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.
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.
