The STM32 family of 32-bit microcontrollers is based on the Arm® Cortex®-M processor.
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.
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.
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.
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 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.
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.
