This article is based on St official demo board stm32f429 Discovery Hardware platform, in order to see the figure of the form of speaking to you to explain the main parameters of LTDC configuration. The code section mentioned in this article is excerpted from my other article "stm32f429 LTDC code template", LCD hardware for 240x320, driver IC for ili9341. The purpose of this article is to let you through a few pictures can master the stm32f429 LTDC controller configuration Essentials, and from t

Just looked at the STM32 General Timer tutorial, in fact, and 51 of the timer use almost. Just because the 32 clock is more complex and can manipulate more registers, it can be more complex to write.General steps to use general timer interrupts:1. Enable Timer clockThis needs to look at the clock tree, so that the corresponding clock will be good. I'm using TIM3 here, so I can APB1 the clock.2. Set the frequency divider and reload value of the timerTimer Interrupt Time: Tout = (arr+1)/[tclk/(psc

see the corresponding source level manual.2 , writing test codeAfter completing the above work, you can begin to actually transplant the work. The steps are as follows: hardware configuration and initialization. Initialization of Ethernet communication configuration. Implement a specific communication process. 2.1. Configuration and initialization of hardwareSince W5500 communicates with STM32 via the SPI interface, hardware configuration and initialization is very simple,

, and write interrupt service function.Because we're going to capture the pulse width of the high-level signal. So, the first catch is the rising edge, and the second catch is the falling edge. Therefore, after capturing the rising edge, set the capture edge to the falling edge. At the same time, if the pulse width is longer, then the timer will overflow and the overflow must be processed. Both of these things are implemented in an outage, so we have to turn on capture interrupts and update inte
