Discuss STM32 and TouchGFX implementations, including configuration, debugging, and optimization.
Hello community!On March 18, we launched a TouchGFX Contest that had for goal for us to see our community's skills and creativity. This contest ended on May 2.We received several interesting projects, and it is now time to announce the winners! Our h...
We wish to always improve our documentation. The best reviews and critics always come from the people that read it, so we would like to use this post to collect your thoughts and feedbacks. Please share what you like, dislike, what you think is missi...
When creating a UI project, you may need widgets that are not part of the TouchGFX library. To create your own graphical element, the TouchGFX team suggests using the Custom Container approach. Since TouchGFX 4.20 it is possible to export and import ...
Posted on January 07, 2016 at 14:39Hi,I'm using a STM32F429 connected to a TVP5150 through DCMI interface.DMA is used to transfer data from DCMI to the external DRAM through the FMC.DMA is configured as follow:hdma_dcmi.Instance = DMA2_Stream1; h...
Posted on January 30, 2016 at 16:52 Hello Guys, I've currently designed a board with an STM32F756IGT6. Connected to the board is an 7'' LCD from Rocktech. Same manufacturer as the 4.3'' LCD's that can be found on the stm32F7 discovery boa...
Posted on February 03, 2016 at 17:46Im trying to get image via DCMI, everything works fine, except DCMI frame received interrupt. When im receiving 320x240 rgb565 image, HAL_DCMI_FrameEventCallback is never triggering, so I redefined dma callback wi...
Posted on February 02, 2016 at 16:52 I have an 800x600 pixels RGB565 image stored in the SDRAM of my STM32F7-discovery board starting at memory address 0xC0390000. What I want to do is saving this image to an SD card. The code for this is a...
Posted on January 28, 2016 at 18:01Hi,I want to evaluate using STemWin in a new project but for the life of me I can't figure out how to use STM32CubeMX to generate code with STemWin. From what I understand it wasn't included but now it is. The down...
Posted on January 25, 2016 at 06:21Hi ,I have configured LTDC pins as follows./* Enable the LTDC and DMA2D clocks */ __LTDC_CLK_ENABLE(); __DMA2D_CLK_ENABLE(); /* Enable GPIOs clock */ LTDC_GPIO_CLK_EN; /*** LTDC Pins configuration ***/ GPIO_Init_St...
Posted on January 18, 2016 at 00:37Hellos,I see there is an inbuiltFMC on the STM32F4x9 MCUs which can interface to various memory types including NAND, NOR , SDR SDRAM. My question is: Is it a good idea to use the NOR or a NAND Flash as a FRAME buf...
Posted on January 08, 2016 at 18:36 Hi there, I'm trying to use the STM32F4 Discovery kit (STM32F4Discovery + BB + CAM [OV9655]; without LCD) to take a 16-bits QVGA (320x240) shot and simply store it in a byte array. Assuming that all DMA...
Posted on January 03, 2016 at 07:37Hello,I'm trying to rotate the display on an STM32F429 Discovery board by 90 degrees clockwise. When I tried to place objects such as text, hline, and vline, the coordinates weren't quite what I expected (in fact,...
Posted on December 21, 2015 at 17:37I have an STM32L152V8 running a large LCD using 1/4 bias and 1/4 duty. It works, but needs a little capacitive decoupling on the bias rails. I am using eternal decoupling pins PA0, PA2 and PA12, have enable extern...
