Discuss STM32 and TouchGFX implementations, including configuration, debugging, and optimization.
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 ...
Hello, we are using an STM32F7, and we are taking camera data which saves to RGB888 format. We would like to compress this to a JPG file before saving to USB, and I see that there is a JPEG peripheral which looks like it fits the bill. However I see ...
Hello, To have a powerful graphical interface, you need a lot of RAM.Can we use external RAM in Quad / Octo SPI for this?The ST kits with screens often have flash in quad/octo SPI but the external RAM is always in parallel (except STM32L4R9I-EVAL).I ...
ST's Appnote AN4861 (DM00287603), para. 4.5.1, "Memory Allocation" discusses "Splitting up the slave memories between masters...."My StemWin application uses a single layer, with multi-buffering ("Front buffer" and "Back buffer"). I am able to set up...
I am trying to get STemWin to work with mbed-os but it seems to be stuck in infinite loop inside GUI_Init() (can confirm the same over debugger).I know for certain that the MCU is not stuck in hard fault since I have another thread running which is f...
Hi, All!I saw the new DMA2D modes appeared in the rev.5 of the Reference Manual (see page 709, field MODE of the DMA2D->CR). They are:100: Memory-to-memory with Blending and fixed color FG (BG fetch only with FG andBG PFC active)101: Memory-to-memory...
Hello,I have been working on the graphics display on the STM32F429I-Disc1, but have been unsuccessful and facing errors so far.Here are my specifications :CubeMX 4.25.0IDE SW4STM32 from AC6Repository FW_F4 V1.23.0 Board STM32F429I-Disc1Purpose : crea...
I've been looking through and following a tutorial in the STM32CUBEMX config manual UM1718, TUTORIAL 8. I'm trying to support a ST7735 display via SPI, but the tutorial setup uses DSIHOST mode LTDC which my F767ZI doesn't support. So, I was thinki...
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...
