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.

According to RM0456, p. 3459So in addition to CCx pins also PB5 and PB14 (DBCCx) cannot be used. The above does not make much sense to me. I imagine (only imagine) that internally DBCC support is implemented like shown below and for "dead battery" to...

@JMYGI The problem, as I see it, is much wider. Recent years ST, instead of supporting community open-source software, selects/builds proprietary closed-source technologies which lock customers into ST's solutions like ThreadX, TouchGFX, and now Nema...

@DmitryR I just ordered evaluation board from another, well-known Dutch vendor with Cortex-M33 MPU using well-documented VGLite GPU2D (LVGL supported). It has much more SRAM than STM32U5G9 and faster clock. I used to be ST-centric engineer but not an...

@Pavel A. There is Cortex-M33 MPU available from another, well-known Dutch vendor with much more SRAM than ST's STM32U5G9, faster clock, GUP2D well documented and LVGL supported. I do not know yet if it is overall better (software support in particul...

@Andrew Neil, @Pavel A. That depends on a particular area, project and expectations but if competitors were much butter, I would not be here and ST board would hold emergency meetings because of stocks falling down sharply. But I am neither ST VP nor...

@Andrew Neil True, but that is not my point.It is not about what you have to or not.It is about how long it takes and how how expensive it is to build a quality product using ST MCU and then maintain it.
