STM32F303RETX synchronous Buck converter hint.

Hello, I am designing a Buck converter to control two Peltier heating or cooling mode. I found nothing available from market, so I designed mine. Target stable temperature, logging and alarm. It control a vaccine VET fridge, stable control temperatu...

I'm breaking out the 0.8mm pitch BGA of a STM32G474VE using a dog-bone fanout and a 1.5 oz outer layer (so, need 6 mil trace/space widths if possible). To facilitate this, is a land diameter of 0.35mm for each ball ok? The datasheet recommends 0.4mm.

MCU STM32L562: With initialising the UART using HAL_UART_Init() the UART-communication is not working. Calculating the BRR like shown in the reference manual gives a working BRR-Value. Is the HAL_UART_Init() not intended for setting the BRR ?

The Project was migrated from STM32L4 to STM32L5. The Baudrate setting with HAL_UART_Init() works fine with L4 MCU. With L5 MCU it returns with an HAL_UART_ERROR_NONE too.

reg addr's for GTZC_TZSC_MPCWMxANSR GTZC_TZSC_MPCWMxBNSR

The doc and SVD file don't have a reg at offset 0x44 (GTZC_TZSC_MPCWM3BNSR).Since GTZC_TZSC_MPCWM3ANSR @0x40 exists, via symmetry I would expect B also at 0x44.The doc does say this:GTZC_TZSC external memory x non-secure watermark register 1(GTZC_TZS...

Single digit year in date code may be inadequate

The STM32 have a 3-digit date-code timestamp, in YWW format, with single-digit for year.Given the rolling 10-year longevity commitment, this may be not adequate to uniquely identify the manufacturing year, e.g. in light of ES0204 Rev 10 2.3.8 (The d...

Maximum rating of the RST terminal of the STM32F765

In the general operating section, it is described as "Input voltage on RST and FT pins".Do you consider the maximum rating of the RST pin to be the same as the FT pin?

ADC channel 12 less accurate than the other ?

Hello,Since two year, I am experiencing an issue with the ADC_CHANNEL_12 (pin PC12) of my STM32F767. I suspect it's a hardware issue coming from the MCU. a stable offset is added (randomly change each time I reboot the STM)this read value (via DMA) i...

What is the largest CNN network applied onto an STM32 board with CubeMX AI?

I saw this video. He say that in these ST boards, they have a trained model that can classify 8 faces.https://www.youtube.com/watch?v=Wzgfm5BH4qYWhat is the largest CNN network applied onto an STM32 board with CubeMX AI and how many objects could it ...

Can I find the end of memory in a bin file?

Hello,Currently, the generated binary file is 1 MB but with 96% of '0'.Obviously, it's quite long to transfer via CAN to update the firmware, mostly for 'nothing'.I can see that the 'end' of my code is: 1000 0000 0100 0000 4078 7d01 0000 0000Is it...
