I am getting pixel data to the stm32. I am reaching the "end of frame flag clearing" at:stm32l4xx_hal_dcmi.c ----> HAL_DCMI_IRQHandler() ----> (line 811)__HAL_DCMI_CLEAR_FLAG(hdcmi, DCMI_FLAG_FRAMERI);I am simply checking cameraBuffer[] pixel array u...
I have an STM32F769I talking OK from SDRAM via LTDC and DSI to a RAMless display (ILI9806E). I'm trying to implement multiple buffers to allow writing to one whilst another is displaying to prevent the display breaking up. What I can't work out is wh...
Hello,I am trying to get a single image the NUCLEO-L496ZG board with a OV7670 CMOS camera sensor using the DCMI HAL library.I am trying to read a single image and write to a USB flash drive connected to the NUCLEO board.I have been trying to use mult...
Looking through the video mode examples that use SDRAM, I see that in BSP_SDRAM_MspInit() a DMA channel is initialised but as far as I can see none of the examples makes use of DMA.Is this a fundamental requirement to operate the SDRAM with the LTDC ...
The header for this function is very cryptic - what, for example, is 'ParametersTable'.All I want to do is check that my display if present by reading the ID codes (its a ILI9806E) but I get a timeout error on the read even though the page select wri...
I used STM32Cube_FW_F7_V1.14.0 to create a project that will use the STemWin library for its touch-screen GUI. The STM32Cube distribution includes a Microsoft Visual Studio project and binary files for a Windows-based simulator in which I'm supposed...
I downloaded the latest STM32 Cube package for the F4 (ver 1.23.0). I'm trying to build Projects\STM32469I-Discovery\Demonstrations\TouchGFX\SW4STM32\STM32469I-Discovery using the free System Workbench (latest 32-bit version 2.7 on Windows 10). The...
Hello,I'm using LibJpeg from CubeMX to decode a jpeg file from SD-card and display it on an ILI9341 display. I found out that decoding will work only, if I decode an vertical rotated picture (240x320). If I want to decode the same picture horizontall...
Posted on June 13, 2018 at 14:33Hi,I found two bugs when trying to read more than two bytes using HAL_DSI_Read(). Bug 1: HAL_DSI_Read() will always return HAL_ERROR when reading more than two bytes.The root cause is simple:HAL_DSI_Read will first ta...
How do you use control the 7-segment display of the stm32l476-disco board using stm32CubeMX and Kiel? Could someone please help me get a 1 to show on it using this setup?I am able to successfully control it using either GCC or Keil with the example I...
