I am working with the NUCLEO-C031C6 board and tried to to make the user push button toggle the user LED but it stays stuck with no change to the buttonStatus variable, always high (1).I added the counter variable to see if it is continuously incremen...
Dear All,I am testing the demo project for the NUCLEO-C071 to implement the USB HOST CDC_ACM (USBX). Below are some doubts that arose after the initial tests:After using the wizard to create the demo project 'Ux_Host-CDC_ACM', opening the .ioc file s...
Hi team What is the correct procedure to initialize FATFS for SDMMC in M4? Kindly provide the application note of the procedure. We need to run eMMC in M4 core EVK used : STM32H745I-DISCO References code: STM32CubeH7/Projects/STM32H745I...
Hello!I am using STM32F427VIT6 and OV5640 camera to stream MJPEG to a webserver. I used DCMI DMA to get a jpeg_frame, size around 10KB to 25KB per image, with almost 30FPS and send it to jpeg buffer in CCMRAM like this.__attribute__((section(".ccmram...
Hi,I am trying to interface Stm32h745 controller with a 240x320 TFT LCD over FMC. Interesting thing is, when I manually control lcd control and data pins(Set them as GPIO_OUTPUT_PP), Lcd works, but when I switched to FMC it does not. Tried lots of ti...
Hi,I would like to know why when I sent the 202 bytes from pc to dev-board via USB HID, the buffer size would only get 32 byte each time, (byte[0]-byte[31])*several times until finished print out all 202 bytes?Couldn't it recieved whole 202 bytes the...
Hi everyone,I'm trying to drive a WS2812 LED strip (20 LEDs - Strip has 60 LEDs) using an STM32L432KCUx, but so far without success.I've tested multiple approaches — PWM with DMA, SPI-based encoding, and bit-banging via GPIO — but none of them produc...
Hello,I'm new to STM32 and trying to learn exciting stuff. I want to light a single LED from my WS2812B strip. For example I will choose 6th LED on my computer and 6th LED on strip will light up.But I'm not sure where to start. How can I access to si...
