STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...

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 ...
I purchased a controller board from HiWonder, who use your STM32 MCU. I asked them if I can use python to program the STM32 but they do not know. Can I use python to program your microcontroller? Do I need to download specific software?
If I want to receive a known number of bytes I can use the library function: HAL_SPI_Receive_DMA()But I would prefer it if when nSS falls to check how many bytes have been transferred and interrogate the DMA buffer.An alternative is to poll, using F...
At startup I do initializations, then go to STOP1 mode. Initializations include setting a wakeup in the RTC and setting the wakeup clock to the MSI clock. The RTC successfully wakes the MCU. In the wakeup callback, I do some things then start a LPTIM...
