Regarding distortions at pins of IC
We are using STM32H743IIK6 microcontroller. When using analog pins(ANA) to receive analog input signals, will their be interference effect if the two pins are next to each other?

Resolved! CORDIC q1.31 to integer conversion
Hello everyone. I want to understand the CORDIC engine, using the nucleo-u575zi board. The guide says that the cordic uses data in q1.31 format. Could please someone explain how to convert results into an ordinary int value? And how to convert an int...
unable to program an external nand flash memory
hi guys,I hope this message finds you well.I am currently working with the STM32H743Eval2 evaluation board with an external nand flash memory "Micron MT29F2G16ABAEAWP" , and i'm trying to run the code provided in the firmware on the same memory but ...
Slight math error in "STM32H7- CORDIC co-processor" presentation
I was looking at some slides that I found called STM32H7- CORDIC co-processor (CORDIC, Revision 1.0) and noticed the following on slide 6: According to this, the fractional number being represented by the fixed-point integer bits is (-1)^s multiplied...
COM port drop out
I have a written C# windows application that receive data continuously from MCP2221A. MCP2221A receive data from STM32 UART through receive data line. When the laptop goes for sleep (in battery mode), it send a suspend signal (it will go low) to the ...
GPIO CONFIGURATION IN TRISTATE mode

Resolved! How to chose a pin compatible processor with larger RAM - STM32F756ZGT6 144-pin
Dear all,Apologies if this is a naïve post.I am trying to find a processor for the product that I am working on with larger RAM and FLASH but it must remain pin compatible to minimise code changes. The current processor is this "STM32F756ZGT6". With ...
Resolved! Regarding ANA pins of STM microcontrollers
We are using STM32H743IIK6 microcontroller. There are analog only pins, designated as ANA. What is the use of these pins? Also, what will be the difference when GPIO is used for analog functionality and ANA pins are used for the same purpose?
Resolved! STM32H5 DCMI maximum input data size
Hi.I want to acquire data from a 5M pixel image sensor (for example OV5640) with YCbCr4:2:2, 8bit using DCMI.(I want to process the image data, so I need to transfer it to memory using DMA)However, AN5020 and RM0481 (Rev1) mention a maximum of 2048*2...
STM32G491 Pin1 Marking
Hey, i got this STM32G491MET6The datasheet does not really help here to identify pin 1, since there are 4 markings to see. Anyone has a clue on this? In the previous revision of this datasheet, Pin 1 is bottom left . Already burnt 2 mcus because of t...
