Hi!A PWM signal with a frequency of 100 kHz comes to the input of the microcontroller. Then, when the pulse falls, an interruption is triggered, which should change the state of one of the output PINs. And now I am observing a situation where the sig...

Hi everyone!I'm trying to use STM32H723 in QUAD SPI mode.CubeMX does project generation but when I trying to compile project at Keil an error appears about undeclared "GPIO_AF4_OCTOSPIM".If I changed it to GPIO_AF4_OCTOSPIM_P1 compilation run without...

Hello everybody!The documentation indicates that this leg can only be configured as an ADC input. In "CUBE MX" it can be defined as different kinds of interfaces. Who should I believe that my project would work properly and I would not be faced with ...

Can't find any documentation for this op amp. Someone can tell you where to get it, as well as a possible analogue? Thank!

If I one to use Molex 1462360001 (it's antenna for NFC with Inductor @13.56MHz 2.11uH), how I need to modifi output block for CR95HF. Because how I can see STM boards use antenna with inductor 430 nH.Molex 1462360001 datasheet https://www.molex.com/p...

Could you share with community initialization code and read/write code for your platform?I think it's will be very helpful.

This is a working project in which we are making the migrate from STM32F4 to the more powerful H7 MCU line. Do you have any real experience on this issue?I am still awaiting a response from the STM team with working examples. When we worked with the ...

I've seen this example. But in my case, it is not informative, since it describes the mode of operation of 8 lines, and I need 4. And I must be sure of the commands that I use.

Thank! I have already found the documentation, but what about analogs from ST, if something with direct compatibility of pins?
