Resolved! Image displayed using Touchgfx for LCD RGB666 is noisy with green pixels when using OSPI RAM

Hi all,As title, I have a custom board using STM32H723ZGT6, RGB666 LCD (480 * 480) with LTDC interface, the framebuffer used external Octo SPI PSRAM APS12808L-3OBM-BA of APMemory. I can display image using TouchGFX, but the image always noisy with so...

I'm implementing TouchGFX on a Custom BoardI detected that the RAM DQS Pin(OCSPI2_DQS) is always low and does not work.

I'm implementing TouchGFX on a Custom Board using the same circuit as the STM32H735G-DK for the external memories. I detected that the RAM DQS Pin(OCSPI2_DQS) is always low and does not work. The display is always grey as the framebuffer is not writt...

Resolved! ltdc not working properly with external ram (octoSPI APS6408L-3OBM-BA) on stm32h723 processor

Hello everyone. I have a question. I am using the stm32h723 processor in a project. I keep my image data in octoSPI external ram correctly. When I show OCTOSPI_BASE_ADRES to LTDC peripheral, the screen is distorted, but when I keep the same image in ...

Resolved! BSP_OSPI_NOR_Erase_Block() fails

I've created a project using STM32H7B3I-DK eval board with all settings default, unmodified, taken from TouchGFX. UI menu is working fine with some resources stored in OSPI Flash memory.Now I wish to store some data in this OSPI memory. The procedure...

Resolved! How to use TouchGFX OCTOSPI Flash to store setup and tuning parameters

Hi,I am using a STM32H7B3I_DK board with a graphics app using TouchGFX. I'm only using 7% of this and would like to use the top end of this memory to store system tuneable parameters, WiFi SSID's, controller tuning parameters etc.Has anyone done this...

Store Framebuffer in OSPI PSRAM?

MCU: STM32L4R9ZIJ6PSRAM: APS1604M-3SQR-SNDisplay: 800x480, RGB888, 24-bitHi, I'd like to use the mentioned PSRAM to store the TouchGFX framebuffer using OCTOSPI in QuadSPI mode.I have tried setting the Frame Buffer Start Address to OCTOSPI1_BASE (0x9...

how to design a custom board for STM32H7B0VBT6 for implementing TouchGFX

Hi.I designed many boards and implemented TouchGFX using several STM32 uC's before...but never used a 100pin uC...So I force to use an admux psram for buffering lcd and other things...I searched a long time and just find two chips of "AS1C4M16PL-70BI...
