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 May 28, 2017 at 09:21Hello!We've found some strange behaviour in STM32F746 when turn on both CAN1 and CAN2 and LTDC is running. In such case there is a synchronization issue on the display like HSYNC sometimes misses its frame. It looks li...
Posted on May 16, 2017 at 21:07The LTDC contains a 64x32bit (per layer) FIFO, when does the FIFO request a new burst of data? I.E. does it start seeking AHB and possibly FMC access at 1/2 full? Any information on the workings of this, beyond what th...
Posted on June 07, 2015 at 22:14Hi I'm looking for a way to transfer 5MP images from OmniVision OV5640 camera sensor to SD card. OV5640 have 8-bit parallel interface. It also features compression engine so the output could be in JPEG format. Is the ...
Posted on December 15, 2016 at 10:37Hi,I'm using BSP Library for STM32469i-Discovery.Create a new project using CubeMX, added some code and compile it.the result is here.my CubeMX project configure is here.No change is made to any configure LCD.here...
Posted on April 11, 2017 at 18:29I have device model, which consist of stm32f407 discovery board, digital camera and 3.95 inch display with ili9488 controller inside. The display is connected to my stm32 MCU with 8-bit 8080-like bus and accepts RGB5...
Posted on April 01, 2017 at 21:411) Probably its only my misunderstanding, but here is a problem:Layer1 have same size and viewable area of display (800*400), pixel format L8 (with CLUT, ofc). I'm planning to put GUI there - occasional partial redra...
Posted on April 03, 2017 at 20:54Hello anyone,Is it possible to take SXGA (1280 x 1024) resolution pictures with this camera?I have found examples of VGA header file, but I cant find anything about SXGA. Thanks.#sxga #camera #sdram #dcmi #ov9655
Posted on March 30, 2017 at 10:14Hi,I want know how ST manage the memory in order to run STemWin library.In my case, I am using F429IDiscovery Board.Firstly, I have seen that in stm32f429i_discovery_sdram.h it is defined the address 0xD000000000 fro...
Posted on March 28, 2017 at 10:20Hi,I am using 32F429I-Discovery Board with STemWin v5.32 and I am not able to show a JPEG image when I load it into a Memory Device.The code I am using is attached to the question.There firstly I draw the image at po...
Posted on March 23, 2017 at 17:49Hello,I use DSI with external 25MHz osc. In some design I wanted to useHSI (is seems supported wrt. ref.manual) but the DSI PLL doesn'tlock at all.I use IDF=3 to have INFIN=16/3>4MHz and NDIV=125, thus Fvco=666MHz.OD...
