1. What is a Download Circuit The download circuit of a microcontroller refers to the hardware circuit used to download the written program (firmware) to the internal memory of the microcontroller. This process is often referred to as programming or flashing. The download circuit includes the debugging interface with the microcontroller and the corresponding circuit … Read more
STM32 has a code tracing feature, known as ITM, which is a very powerful debugging function that can replace serial input/output functionality, requiring only one I/O line to implement. Of course, its benefits are not limited to this; when debugging embedded operating system code, you will find it quite convenient. However, the focus of this … Read more
During the firmware upgrade process of the STM32 microcontroller, many engineers choose the IAP technology, which allows firmware updates to the microcontroller via the host computer while the application is running. However, occasionally, there may be a low probability of encountering a runaway phenomenon. How to solve it? 1. Check Power Supply Voltage Ensure that … Read more
A ASIC (Application-Specific Integrated Circuit) – A piece of custom-designed hardware in a chip. address bus – A set of electrical lines connected to the processor and all of the peripherals with which it communicates. The address bus is used by the processor to select a specific memory location or register within a particular peripheral. … Read more
Understanding OBG in Microcontrollers: The STM32 microcontroller’s core (Cortex-M3) contains a hardware debugging module that supports various complex debugging operations. The hardware debugging module allows the core to halt when fetching addresses or accessing data—this is the assurance we have for online simulation during microcontroller development and debugging.When the core is halted, both its internal … Read more
