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...
Hi everyone,So, i would like to test SPI1 communication on my stm32F103, using just the clock and MOSI line by sending 0x55 data on MOSI line , but when i see the traces on logic analyzer, i'm getting a weird values !as seen in this capture picture, ...
I am trying to emit data on SPI MOSI without enabling the corresponding SCK pin. This is useful for instance to control WS2812-type LEDs.However when I use `HAL_SPI_Transmit_IT` to transfer 3 words, the IRQ Handler gets called 3 times (triggered by ...
Hi!I'm using an ADC line of the STM32 MCU to read battery voltage that goes from 6.7V to 8.4V.The battery voltage is given to the MCU via a divider (by 4, so the maximum voltage given to the ADC line of the MCU will be 2.1V).I wanted to know, if ther...
Hello, We are currently working on touch sensing in STM32L1V8XA Microcontroller Below are the queries :1) How to get started with cap sense touch key in STM32L1V8XA Microcontroller. Do we need to use STMTouch touch-sensing library https://www.st.com/...

Hello, I use STM32L476 for very low power project. I also use an external RTC because it is temperature-compensated. My question is : What is the best way to backup some bytes whitout RTC backup registers in order to enter in shutdown mode.I had the ...
I am trying to debug my USB and in the process I am going through all the registers defined in the datasheet vs stm32h745xx.h file and I see that in some cases the .h file has registers defined that is not in the datasheetGUSBCFG_CTXPKT : in .h but n...
Lets hope someone has a felicitously revelation, or a clue.I am using a custom board with a nice stm32f105rbtx, fed with external XTAL.Everything worked like a charm untill i configured the clock to be 72Mhz and readjusted the can parameters in CUBEM...
