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...

Resolved! stm32h745 disco
Hello, i bought this board and the board was burned with sw with signal genrator and other things. Somone can send me the .HEX file that i can burned it again? i cant found this file.
Resolved! Bootup Delay on STM32F446
Hello,I am running simple LED Blinking on STM32F446RE.I want to measure the Bootup Delay once it is Hard Reset.I have conducted the following test through Oscilloscope and Logic Analyzer.I want to know and prove this through calculation.Is there any ...
Resolved! Using ADC1 and ADC3 with DMA and timer
Hello everybody!I am using STM32F429 as my central controller for a project. I need to read 20 ADCs and process the signals by the 10 kHz sampling-time. I am using 14 channels of ADC1 and 6 channel of ADC3. Before, I have done it for one ADC when I u...
Resolved! ADC on Nucleo 401RE
Hello everyone, im trying to understand how the configuration and the use of the ADC is usued on a NUCLEO401RE. I've read the datasheet and reference Manuel but still its not clear.I have configure the pin A0 on CubeIDE to be an ADC input. But now i ...
