Hi,I have a custom board with STM32H7 & TouchGFX.I'm using DMA triggered by interrupt to sample datas with my ADC. Without DCache enable, it's working well. But TouchGFX fails if DCache is disabled (problem meet by others here: https://community.st.c...
Hi,I have a STM32F779BI on a custom board that communicates with a LCD display using the LTDC interface in 16bits (480x272). I am using a single buffer inside the RAM of the MCU. So far TouchGFX works pretty well but once i activated the Software pac...
In my project, SD card was used to store the video, JPEG peripherals +DMA2D were used to convert the video format and finally displayed on the LCD screen, but only the first 4 frames could be converted each time, and then HAL_JPEG_DecodeCpltCallback ...
Posted on January 24, 2013 at 08:05Hi,I am using STM32F4 discovery board and ported STM32_Eval DCMI(From OV2640)example to work with OV3640.I used OV3640 to grab RGB image using settings from http://www.arducam.com/download/library QVGA setting. I c...
I wish to drive (write output data streams) to a parallel-interfaced LCD display. There would be 8-32 bits of parallel data (tied to MCU GPIO output lines) and a strobe or clock line (also tied to MCU GPIO output line) to cause those bits to be trans...
Hi everybody,I'm developing a simple gui on an STM32F429 microcontroller with the use of the STemWin grapich library. Everything is working well till I'm using just one framebuffer; now I would like to use double buffering to optimize the interface a...
Hello there,I have a problem with a stuck TouchGFX task. When the fault occurs, the TouchGFX task uses almost 100% CPU time and completly prevents lower priority tasks from executing. It seems to be stuck at a DMA transfer, altering between LockFreeD...
I use CubeIDE 1.9.0MCU packate STM32H7 V1.10.0My project generates separate files for each hardware. In this case "dcmi.c" and "dcmi.h"DCMI is set to Slave 10 bits External SynchroI use DCMI_PSSI DMA1 Stream 2 Perpheral to MemoryCubeIDE generates fol...
I am using FMC LCD interface to power my TFT LCD controlled by SSD1963. FMC data width is 16-bit, and below is a workable code using pixel-by-pixel transmission.void lcd_fill_pixels(uint16_t sx, uint16_t sy, uint16_t ex, uint16_t ey, ...
Hello all,I'm using the HAL library for the camera, specifically I'm using the function: HAL_StatusTypeDef HAL_DCMI_Start_DMA(DCMI_HandleTypeDef *hdcmi, uint32_t DCMI_Mode, uint32_t pData, uint32_t Length)In the function are many return HAL_ERROR, an...
