STM32H750 to STM32WB

I am looking to add bluetooth onto my project. I have an already developed nRF52 project I could use and just connect it through UART to the STM32H750 or migrate my STM32H750 to a WB based MCU since it has onboard bluetooth connectivity. I was wonder...

STM-L432KC UART1 interrupt does not trigger from serial line data

Hello,I'm new to STM controllers and working on a project where the STM gets data over serial line from another microcontroller. For this UART1 is turned active and mapped to ports PA_9 (TX) and PA_10 (RX), so data from other controller flows in on P...

Do UFQFPN packages of STM32 devices (e.g. STM32G0C1KEU6) feature wettable flanks?

Do some QFN STM32 come with side wettable flanks?

Hello,TN1236 explains the advantages of QFN packages with wettabls flanks? Do any QFN STM32 have these side wettable flanks?

Build compiler error

I am using STM32U575ZI cortex- M33 controller. I am able to generate a code for the same micro controller in CUBE MX. But in Cube IDE I couldn't able to build the files. It shows some compiler error. like,"../Drivers/CMSIS/Include/cmsis_gcc.h: In fun...

STM32H753 How to test ECC on L1 cache

Hello,I am using a STM32H753. I would like to test the ECC on the L1 cache. In my understanding, a double bit error on the data cache would trigger a BusFault: is there a way to produce it? Thank you

EMW3080 NetxDuo driver for STM32H5

Hi,  I would like to test the EMW3080 with the STM32H5, as I understand it is necessary to load the firmware provided by the ST in order for the EMW3080 to work with the driver provided for the B-U585I-IOT02A board. Correct?Does ST have plans to laun...

LWIP

Hey, I am using NUCLEO-H743Z12 and I am trying to configure the ethernet peripheral (and LWIP) with the cubemx with no success (I red lot of manuals online).In the end, I cant even ping my board.Please anyone can help me with the configuration?I main...

STM32L552 I2S DMA and CDC continuous transfer problem

I have an ADC connected to my MCU using I2S. MCU configured in I2S master receive mode. MCU supplying the ADC with 12MHZ MCLK. MCU sampling freq is 48 KHZ(Actual is 46.875 KHZ), Number of slots are 4, Data size is 16bits and I2S standard protocol. Us...
