3-Wire SPI to demo board not working?

Good afternoon.I have configured SPI2 on STM32L476RG as Master Half Duplex, clock = 4MHz, CPOL = 1, CPHA = Edge 2. I am connected to a Pololu 2736 demo board (LSM6DS33). The timing diagram for the part shows resting clock as high (CPOL = 1) and MIS...

How to Read & write application code with comments STM32.

I want to read and write application code with comments in STM32 MCU flash or external memory.When I read flash from STM32 MCU I want comments also present there​ in code.​How can I do this? It is possible with MCUs ​inbuilt memory or need external m...

Does anyone know when STM32 MCUs are going to be available on the market? Is there any estimate time known?

Well, I know that this is the most commonly asked question these days, but let me please ask it. Maybe it will help me and future readers of this post.I was working with STM32 MCUs for a quite long time, works great and it is planned to use new versi...

MCU packaged in a MBB

If a MCU is packaged in a MBB, is it then necessary to put the MBB in a climate controlled cabinet in between usage? If what is the recommendation of when to put in, how many days, weeks or maybe months can be accepted before the need of a cabinet?

I am working for stm32h753zi and i am trying to measure ADC reference voltage. But i got 5.74466228 instead of 3.3v.Please any one give me the guidance. I have attached steps i followed, Thank you.
