This model is configured for the STM32F4-Discovery target. The aim is to use blue button to turn it on and off the four LEDs. I would love to see more of this kind of tutorials (I would like to learn to use external interrupts). I will not explain CMSIS and other MDK Components in detail. See the video on you tube. c добавив в него функцию задержки(т. stm32f4 usb host and device This post is a result of several hours of hard work, thinking, planning, trial-and-error, debugging, and searching the internet for working code in order to make the USB peripheral of a STM32 act as an USB device (mass storage) and HOST (mass storage too). c, etc. Some extra resistors and one cap is on one side, but they are not required for the LED blink project. I’m able to compile and run basic LED blinking code using the mbed framework but I’m having trouble with the non-mbed stuff (I’m guessing cmsis?). This is a very simple code to blink 8 LEDs. I tried your example with my STM32F4 DISCOVERY and it worked fine. This works for the famous Blue Pill, but there are a lot more boards out there. Example 1: Blinking LED (aka, the Hello World of Electronics) This is my first tutorial for the Lattice ICEstick board. For an embedded system, the time tested tradition for saying ‘Hello World!’ is to blink an LED. elf (gdb) target extended localhost:4242 (gdb) load (gdb) continue After the `target` and `load` commands, the board's LED will blink to slid green. This sample is extremely simple, but it shows you the basics of controlling an external GPIO pin – have fun!! and look out for my next post where I will be showing you how to control the brightness of an external LED using pulse width modulation. In this video, I have used STM32F401RE Nucleo board, but you can use any board or any STM32 microcontroller. Nice work indeed 🙂 Just one question! Why do you select the SPI_NSS bit as being Software controlled, when STM32F4 Discovery Board is a new generation board that has high capabilities such as low cost energy, 32-bit microprocessor, very short response time and so on. This example, just as the one for STM32F4, is configured for linaro toolchain, but this time it is not mandatory. Ross Wolin did a great job writting makefiles for the peripheral library and reading his makefiles showed me how to actually work with the library, which is what I wanted because I like to… zhang-wenchao changed the title stm32f4_disco samples/basic/blink_led ,Choose supported PWM driver stm32f4_disco and frdm_k64f samples/basic/blink_led ,Choose supported PWM driver Nov 7, 2017 This comment has been minimized. Each and every step is explained in detail. This example was tested on STM32F4-Discovery and does the following things: STM32F4-Discovery_LED_Keil. Stop blinking LD1 on STM32F4 Discovery I need to sample them w/ the 32-bit ADC to be able to see them
