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.

The SunFounder Zeus Car Smart Car Kit for Arduino UNO is an educational kit designed for beginners and children to gain hands-on experience in electronics, robotics, and programming.
It’s very fun to upgrade and programming with It.
In this article we are going to apply two upgrade: light and WiFi boost.
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.
