Resolved! native i3c support
Any chance STM32 MCUs will adopt native i3c support any time soon? Many new devices, including some from ST (like the LPS22HH), support it. It's a compelling (new-ish) standard.

Resolved! SRAM parity flag not set in NMI handler
Hi allI'm trying to distinguish between the interrupt sources in the NMI handler on a STM32G031 - particularly the RAM parity error.I have everything in place and I can provoke a parity error. The NMI ISR is called as expected, but if the SYSCFG_CFGR...
Resolved! STM32L0x0, are "unique ID bits [95:64]" of "Unique device ID registers (@0x1FF8 0050)" uniques?
I am working with STM32L010C6T6 MCUs. I need a way to consistently and uniquely identify each MCU with as few bytes as possible. The 96 bits "Unique device ID" register seems ideal but what is the minimal number of bytes I need? Are all 96 bits manda...
On the 32F407 is it possible to have DMA USART2 receive terminate on an idle line or say 20mS timeout?
I´ve read some MCUs support idle line events, but looking through the datasheet can´t see how to implement this.I could DMA 3 bytes at a time, but best would be to have DMA completion triggered after idle or timeout.
Resolved! Error in PM0214 Programming manual with "vmla" instuction?
I think there is an error in the PM0214 Programming manual "STM32 Cortex® -M4 MCUs and MPUs programming manual". The multiply and accumulate instruction is called "vlma" throuout the whole document. Other programmin manuals (e.g. for STM32H7) as well...
How to output two DACs through stm32?
I have a STM32-G071RB. I want to generate two sine outputs. one for reference and the second with a phase shift. Unfortunately, there is only one DAC port. I got an extra board but then I realized I need communication between the two boards to (I fou...
UART communication problem. No reception
HelloI am trying to communicate with a Daly BMS in UART. I tried at first with an arduino board where I got the desired frame but when I tried with a custom made STM32F072 board. But during this test I can't get any response from the BMS.The BMS work...
