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 */...

Hi, I would like to know the maximum frequency input supported by STM32F031C6T6 and the total ADC error rate expected for this MCU.

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...
