cubemx

These two days have been debugging Stm32f4 TCP, and want to apply to Freemodbus TCP, so that my device can integrate network control. Because now most of the use of STM32 should use ST dedicated configuration software STM32 Cubemx to carry out the initial project of the program, there is a benefit, is to speed up the development progress, I am also here in this software development, I just to write down their use of the process,

at the moment, I think the biggest convenience of Stm32cube is that you can use STM32CUBEMX software to graphically configure peripherals. First posted on the official website of the PDF,Getting started with the STM32CUBEF4 firmware package for STM32F4 Series "UM1730 User Manual".From the document of a picture, clear introduction of the cube firmware level, I think for our efficient and rapid development, the temptation is quite big, but the introduction of the official website and online resour

library to generate initialization files and corresponding projects. In the Cubemx interface, after the selection and configuration of the various peripherals, in Project\project setting\advanced settiing The following graphical interface, you can choose the type of library to use: Hal/ll. In addition, occasionally people ask and where ll library, in fact, LL library function is in the same directory as the HAL library function. Take STM32F4 as a

1, configuration steps in Cubemx (1) RCC Open HSE Peripheral clock Configuration, HCLK = 72MHZ (2) USART1 Asynchronous transceiver Complete the above configuration to generate the code for the Keil project. 2, Test procedures: In the Serial debugging assistant to send data to the UART1, using the method of interruption, stm32f103 received a string after entering the interrupt service function, and then write the received data like a serial po
