Can I use STM32F103VCT6 to make TFT-LCD(ST7789) display by FSMC?
I used STM32CubeMX V5.6.1 to create a project for STM32F103VCT6,I wanted to make a 2.8" TFT-LCD(ST7789) display, it does not work!The configuration parameters in STM32CubeMX:Connectivity -> FSMC: NE1 Chip Select LCD Register Select: A23 Data: 16 bits...
AVI format with Motion-JPEG
Hi,Reference the Official Code from CubeMX in STM32Cube_FW_H7_V1.6.0 -> JPEG_MJPEG_VideoDecoding.And I have built the code for my own board test, but I got some error on it.When I debug the code, it always get in HardFault at StreamSize like the ima...

Posted on November 29, 2017 at 09:01Hello,I'm working on a custom board : stm32l073 + LCD screen ( matrix 4 x 25 ).I can't understand how to use HAL_LCD_Write function.As far as I understand I just need 3 parameters in order to write LCD : COM: 0-3 ...
emWin_PNG License issues
Hi,We have successfully integrated Segger's emWin_PNG library (https://www.segger.com/downloads/emwin/emWin_PNG) with STemWin on STM32H7 series MCU. Segger License agreement shown during emWin_PNG library download has below wording which might be an ...
STM32L4R7VI DCMI with large image resolution
Hi Community,I'm trying to get an image from a camera with a resolution of 752x480.In this case, the size (752 * 480) / 4 = 90240 exceeds the maximum DMA transfer length 65535.And I get a broken image: 1/4 of the image is duplicated.Original image:DM...
STM32H743zit DCMI DMA not Working.
I can not get the DCMI Working with OV7670 Camera. The Hardware is correct, Camera setup is correct. HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_CONTINUOUS, (uint32_t)framebuffer, sizeof(framebuffer)/4); The DMA Always Fails. The problem is with the STM...
STM32F429I-DISC1 Project example BSP LCD String look like salt noise
Hi I buy a STM32F4 discovery board, and I run example from ST offical github.The Project in STM32CubeF4-master\Projects\STM32F429I-Discovery\Examples\BSP (IDE: MDK-ARM), I think the LCD will show some string, but I got some salt noise.Other LCD exam...
STemWin future?
I see that in G0 G4 Folder STM32Cube\Repository\STM32Cube_FW_G0_V1.3.0\Middlewares\ST STemWin is missing. I wonder if there is a reason for that, ie does it still work? (CRC hardware lock ok?)
STM32F769 calculates wrong NMCU during header processing?
Dear All,when I parse a simple jpeg (300x100px, 4:4:4 subsampling), the nmcu value reads 468 (?=floor(300*100/64)) instead of 494 (=floor((300+7)/8)*floor((100+7)/8)) after the header processing finished interrupt.All the image data is processed corr...
