01 Identifying the ProblemI have a STM32F407G-DISC1 development board, with the MCU being STM32F407VGT6. Recently, I needed to use this board for a test, but it turned out to be non-functional. After sitting idle for a long time, it was prone to failure.I conducted some troubleshooting, first checking that there were no short circuits between … Read more
Introduction I wrote this porting guide because a colleague from my WeChat public account asked me to write a tutorial on porting, so I wrote this article at their request. Preparation Before porting, we first need to obtain the official source package of FreeRTOS. Here are two download links: One is the official website: http://www.freertos.org/ … Read more
Regarding the reference voltage of the ADC, I have found that many engineers do not have a clear understanding. This is especially true in scenarios where the battery directly powers the MCU and the ADC is used. This article provides a brief summary. Taking the classic STM32F103 as an example, the reference voltage for the … Read more
At the request of readers, Embedded ARM will continue to introduce domestic products that can replace STM32. Today, we present the Dongsoft Carrier ES32F369x, which can perfectly replace STM32.Dongsoft Carrier was formerly known as Shanghai Haier Integrated Circuit Co., Ltd., and later renamed Shanghai Dongsoft Carrier Microelectronics Co., Ltd. Dongsoft Carrier has an 8-bit MCU … Read more
Introduction ST has released three types of library functions to facilitate customers in quickly developing STM32 series MCUs. From the earliest standard peripheral driver library to the later Cube HAL, and then to Cube LL and direct register manipulation. How efficient is the code of these libraries? This article will provide a rough analysis of … Read more
Introduction First of all, the serial port is an essential tool for anyone involved in hardware and embedded software, especially for debugging systems with MCUs or CPUs. During the debugging process, the first thing we usually do is to light up a GPIO. This has been covered in our previous content. From schematic PCB to … Read more

The motor drive uses the TB6612FNG module, and there … Read more
Why nanopb is an Embedded MarvelRecently, while working on STM32/ESP32 microcontroller projects, I found that using the traditional Protocol Buffers library can almost deplete flash memory and RAM. Yet, there is a desire to use .proto to define messages, which is efficient and cross-language. nanopb is like a savior, with a code size of just … Read more

What is a Software Timer A software timer is a timer simulated by a program, which can be simulated by a hardware timer to create thousands of software timers. This allows the program to use a large number of timers without being limited by insufficient hardware resources, which is one of the … Read more
