STMicroelectronics STM32 32-Bit ARM® Cortex®-M MCUs are based on the Arm Cortex-M processor and offer a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation. This is achieved while maintaining full integration and ease of development.
This guide demonstrates how to send emails with attachments from STM32 microcontrollers using SSL encryption, like Gmail. It covers using w5500 and enc28j60 for network connectivity and SD cards and SPI Flash for storage. With detailed setup instructions and coding examples, it enables secure email communication in STM32-based projects.
EByte RF E70 433/868/900 T14S2: pinout, datasheet and specs
In this article, we will dive into some technical details of the Ebyte LoRa E32 module integrated with the STM32 microcontroller. One key feature that we will explore is the WOR (Wake on Radio), which is a significant factor in the world of low-power long-range communication systems.
This article, the fourth in our series, provides an in-depth analysis of the different transmission types that can be realized with the EByte LoRa E32 module utilizing MicroPython. By understanding these transmission modalities, developers can effectively harness the power of these tools and tailor their applications to meet specific needs.
The Ebyte LoRa E32 library is a comprehensive tool designed to facilitate seamless communication with LoRa wireless modules. Developed for programmers and tech enthusiasts alike, the library enables a smooth interfacing with Ebyte’s LoRa E32 devices using MicroPython, a lean and efficient implementation of the Python 3 programming language.
In this article, we finally delve into the backup domain, a crucial step towards resolving the issue of state preservation across sleep modes. We initiate with a comprehensive exploration of the RTC backup registry, subsequently moving onto an analysis of the backup mechanisms for SRAM memory.
Another important element of STM32 is the backup domain. After a brief introduction to the topic, we will evaluate and test the standard solution for RESET, namely the use of variables in the “noinit” and “persistent” memory areas, a very interesting management. And we will write some simple functions to check the features of our devices.
After the timed, alarm and Serial wake-up, the most used one is the wake-up via an external source. In this case, we must pay attention to the pinout of our device to select the correct pin in the correct situation.
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.
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.
