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 ...
I put a ScrollWheel inside ScrollableContainer, then the ScrollWheel can not be scrolled.How to go around it?
In my opinion, the framebuffer lock is used to prevent the mutual exclusion of the framebuffer, but touchgfx itself runs in a single task, so is this lock used to prevent the simultaneous access of touchgfx software rendering and dma2d rendering? The...
Hello, I want to update my display data via SPI DMA. The display has 480x320px and I have chosen a 3 bit color coding, so that I can send two pixel within one byte. So my framebuffer has a size ox (480x320)/2 = 76800 byte. But when I want to transm...
Hello,I am writing to you because I need help to solve my problem.Here is the situation:I am learning to use emWin. I use an OLed screen with an SSD1305 controller. it's a monochrome screen.Currently I communicate by SPI bus.ST does not provide a dri...
I understand the simulator doesn't know about GPIO and so on. That being said, if one wanted to manipulate the hardware from the UI actions (say, set an LED), what's the best way to do that?Two ideas I have: 1) Use the preprocessor to comment out any...
I'm trying to figure out how to interface with the LCD controller on the STM32373C-EVAL board. The driver code I downloaded from the keil.com queries the chip for an ID and checks to see if the chip is an ILI9328 or a HX8347, but neither ID matches. ...
Hello everyoneHas anybody ever been successful in configuring STemWin library for external SRAM with STM32 MCUs? (I struggling with this for a couple of months)
hi, i have a touchGFX app working smoothly with some business logic on other tasks; that's all good and well.now some screens have to show frequent data from biz logic, and others not. so i'd like to make the biz logic controller aware of the screen ...
Hi.I create project in touchgfx and run ok on 32F746G-DISCO board.But in keil compile error. image of errors in attachplease help me.thanks
I've purchased a STM32373C-EVAL board for some academic work which relies on the LCD, among other peripherals. I've generated code with STM32CubeMX and set up my Keil environment with the runtime environment (with the LCD and SPI components, and set ...
