Hi All,I am looking for any simple working example on how to, let's say, draw a circle or rectangle on the screen using the new GPU2D aka NeoChrom aka 2.5D aka NEMA GFX.Does such example for STM32U5G9 already exist? I know that it has to use compiled...

Hi All,Not so long ago ST has selected Microsoft ThreadX as one of its its strategic technologies.In my opinion it is a very good RTOS. The problem is that it was supported by Microsoft only, no other community project integrates with it, e.g. mcuboo...

Hi, I try to use IIS3DHHC as a simple inclinometer. I learnt that to get stable readings it may be a good idea to process raw data using Extended Kalman Filter (EKF). Some ST demonstrations available on YT mention that as well, but I found no source ...

Hi ST,I have some doubts related to writing to M24M02E-F EEPROM.DS14157 (Rev 1 - December 2023) in section "6.1.2 Page write" states:1. "The page write mode allows up to 256 bytes to be written in a single write cycle"How is this achievable since the...

Once I enable UCPD for STM32U5G9 source mode, Cube MX (the latest version 6.12) generates code which does not compile. I am sometimes wondering what is CubeMX testing process - if it exists, ofc.

@GaetanGodart Nothing to be sorry about, this is just the official explanation that you follow and provide. I do understand.Do I correctly understand that ST can share only Nema GFX library API documentation, not the low-level hardware docs like regi...

@GaetanGodart I would not call it high standard. Modern standard would be the more accurate description.Currently I study LVGL Nema GFX implementation. I have not requested access to docs via ST yet.Do I correctly understand that only Nema GFX librar...

@onderdelen I agree, disappointment is the right word. The more I think about it, probably lack of internal flash is the biggest concern. Sure, one can add external flash but what about security? Code would have to be stored encrypted and then decryp...

@RaidenMEI > the gpu cant draw cricle driectlyDo you actually have this knowledge or just the illusion of knowledge?

TDJ · 2024-12-13

@GaetanGodart This is true, and in the actual product development process there is no room for any "maybe".We cannot hope for a comprehensive response, neither from ST nor LVGL team - although I am LVGL contributor who developed full DMA2D support. T...
