Sdio DMA code generated by the Cubemx tool does not work

Near the row in learning to use ST's Cubemx tool, so take the Atom Electron board to do the software debugging target board to do the test. From porting the serial port, FreeRTOS waits all very smoothly, but when does the sdio transplant the time discovers a strange phenomenon, each time writes the card, will receive a wrong callback. So in the 21IC of the St Forum published the relevant posts. Also very grateful to 21IC Netizen huzi2099 help. Rela

STM32 UART Single-line half-duplex mode (cube version)

STM32 UART Single-line half-duplex mode (cube version) 1. IntroductionIn some cases, a three-wire serial communication is required (only one of the signal lines), which requires a single-line half-duplex mode for communication. In this case, in the process of data protocol transmission, the signal end needs to switch back and forth in the input and output mode. Alternatively, the transmit and interface of the control port can be short-connected. In this case, STM32 provides the Half-duplex funct

STM32 Freemodbus TCP Communication

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,

[Stm32f429-disco-hal] 1. Let's talk about some things about stm32cube. Then, Start with it ...

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

Comparison of code performance based on different STM32 library functions

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

The MCU is very important for the debugging of the communication interface--uart
