DS9826 states that "The VDDIO2 supply is monitored and compared with the internal reference voltage (VREFINT). When the VDDIO2 is below this threshold, all the I/Os supplied from this rail are disabled by hardware. The output of this comparator is co...
helloI have a question about the tutorial for the DFSDM excel file.https://www.st.com/content/ccc/resource/technical/document/technical_article/group0/1b/40/1d/43/1b/8d/47/65/dfsdm_tutorial/files/dfsdm_tutorial.xlsx/jcr:content/translations/en.dfsdm...
Okay so I'm trying to use FSMC in order to control 16 bitlines and a (custom) clocksignal for driving multiple LED drivers. (the final goal see "data-signal")My first goal was to be able to drive the 16 bitlines, this works as expected. (see "without...

I have one stm32lL011 20 pin chip. And nothing more than just this chip, it's a bare chip. How can I turn on a led using a touch button? I don't know what to do, can you write me step by step what to do?Thank you all =)
Hi everyone,I am trying to create an external loader for my project by ST's "How to create an external QSPI loader MOOC" lesson. Actually lesson's github repository have microcontroller and quad spi flash configurations that I use. I just change som...
Hi everyone, my project using STM32L433ccu6 MCU (PCBA from china). ADC value read out freeze 2048 (0x0800) , but in my prototype with component from Digikey or Arrow everything ok. And I try to replace MCU I bought from Digikey to PCBA board , It's w...
Hii would like to use the backup SRAM of the STM32F407 MCU to share boot flags between the bootloader and main firmware.The flag should be used to signal a "boot into bootloader" requested by the main firmware.To boot into the bootloader the main fir...
I am using the STM32F302R8 for motor control application. Need to do pulse-by-pulse current limiting.I have a BLDC drive board that has a comparator that can be used to give shutdown signal to the PWM. For this purpose, I need to give the comparator ...
