Ⅵ. How to use STM32F103RET6?


STM32F103RET6 is a single-chip microcontroller that integrates processor, memory and peripherals. It uses the ARM Cortex-M3 core to provide high-performance and low-power computing capabilities. Users can flexibly apply it to various fields through programming, such as medical equipment, power tools, industrial control, smart instruments, and automotive electronics. When using the STM32F103RET6 chip, users need to write a program and download it to the chip. Program code can be written and debugged with the help of various development tools, such as Keil, IAR, etc. The main functions of the program cover data collection, processing, storage and transmission. The peripheral resources of the chip can be flexibly configured and controlled through programs. For example, timers and counters can be used to implement functions such as PWM control, timing measurement, and scheduled interrupts; analog signals can be collected with the help of ADCs; convenient data interaction with external devices can be achieved through communication interfaces such as USB, CAN, USART, SPI, and I2C. . In addition, the chip's low-power mode is also one of its notable features. By properly configuring the chip's low-power mode, users can effectively reduce power consumption and extend the life of the chip. Commonly used low-power modes include standby mode, sleep mode, and stop mode.



Ⅶ. How to carry out the development of STM32F103RET6?


The development process of STM32F103RET6 is as follows. First, we need to build a development environment suitable for STM32F103RET6. This usually includes an integrated development environment (IDE) and related toolchain, commonly used IDEs are Keil uVision, STM32CubeIDE and so on. After installing the IDE, we also need to install the STM32F103 packages or drivers to be able to compile and debug the code. In the hardware design phase, we need to design the board and peripheral circuits of the STM32F103RET6 according to the specific application requirements. This includes selecting the appropriate power supply circuit, clock circuit, reset circuit, and so on. Also, we need to select and connect appropriate peripherals and sensors according to the functional requirements. Software programming is the core part of STM32F103RET6 development. We can use programming languages such as C or C++ for programming. When programming, we need to familiarize ourselves with the register mapping, interrupt system, and peripheral interfaces of STM32F103RET6. To simplify the development process, we can use the officially provided library functions for development, and of course, we can also directly manipulate the registers for the underlying programming. After completing the programming, we need to debug and test the code. We can use an emulator or debugger to connect to the STM32F103RET6 for single-step code execution, variable viewing and other operations. At the same time, we can also use tools such as the serial port debugging assistant to view the output information of the program for troubleshooting. After debugging is completed, we need to burn the program into the STM32F103RET6 chip. We can use burning tools such as J-Flash to burn the compiled HEX file into the chip. After the burning is completed, we install the chip into the board for the deployment of the actual application. Above is the whole development flow of STM32F103RET6.
