ADC Common-mode range
Hello, I am trying to understand the common-mode range in differential mode - according to the data-sheet, it looks like it is quite narrow:Could you please clarify?We wish to wok with 0 to 2.5 V signals.Thanks.

STM32F107VCT6 top marking is different with datasheet，“Z�? is shows in different position.
We found that the parts which we received its marking is different with datasheet. What is the reason for the different position of screen printing?Please help to provide MFG explanation.
unique die and device identifier
Hi, STM32 has a unique device identifier and unique die identifier. is there any possibility to read the value of those ids and also to change their value? Thanks
Resolved! how to use TIM3_ETR to remap TIM3_CHx
Hi all,I haven't worked with ETRs earlier. I am currently working with stm32G491, I want to use TIM3_CHx, as an input capture. due to design problems, I am not available to use those pins. but I can use the TIM3_ETR pin. so is it possible to remap to...
How to establish Wi-Fi communication without external Wi-Fi network?
Hello!I'm currently trying to use Wi-Fi as a way to communicate wirelessly between two B-U585I-IOT02A boards, but don't need connection to the internet. What I'm trying to achieve is a way to get a string or some other data from one board over to ano...
How I can program STM32U5 via USART from Embedded Linux?
Hi,I've used stm32flash on my processor with embedded Linux to program STM32U5 via USART. When I enter a command ./stm32flash /dev/ttymxc0 (usart interface connected to the STM32U5). I got a message "Failed to init device".On the stm32flash site I fo...
How do I find the wake source on a STM32H7A3? We have a product that under certain circumstances, will wake when it's not supposed to.
We track known (i.e. programmed) wake sources and report them at wake. The wake is not reporting any know source. The wake seems to be a loop, i.e. as soon as we enter sleep, the wake occurs. /* Set SLEEPDEEP bit of Cortex System Control Register */...
Simple write to flash memory address ... no fault? nothing?
Does doing a simple write to the flash address space not result in any kind of a BusFault or other error interrupt?After debugging an issue wherein I did not realize that I was running `qsort` on const data that was residing in the, I was a little su...
Getting HARD fault while receiving data from Serial UART2
I am working on a project where I have managed to detect any printer using USB driver provided by STM-HAL.All this code is developed on STM32F407VG MUC Discovery Board. Which is working fine and I am able to print the labels as i want without any err...
