New possibilities for the ultra-low power segment!

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...

Resolved! TRACECLK freq. in STM32H5

I do not see any information on the datasheet or reference manual, how is the TRACECLK in STM H5 (particularly 563 if it matters) derived ? Is the TRACECLKIN SYSCLK or FCLK ?

sending same data over DMA

I'm using stm32u535 and LIS3DHTR accelerometer. The accelerometer has a 32 FIFO buffer, and I set it up so that it sends a signal to interrupt pin when FIFO is full. To read data, I need to send 0xE900,0x0000,0x0000 (saved in uint16_t  ACC_READ_ALL_D...

Flexible SPI clock frequency

Hi,We have a need for arbitrary SPI clock frequencies. I looked at ~10 families and most STM32 micro-controllers seem to be limited to prescalers that divide the PCLK by a power of two. I found the STM32H7 but it is wildly over-specified for our appl...

Wakeup from sleep or shutdown via TSC

Hello dear community. I am working on a project with a STM32L462CEU6 powered by battery. In this project we are also using TSC. Now I want STM32 to go in sleep or shutdown mode and wakeup when a touch pad has been touched. So the goal is that TSC mea...

Resolved! HRTIM 100% duty cycle

Hello,is there a solution to generate duty cycles between 0...100% with the HRTIM? I tried up-counting mode and center-aligned mode, but I wasn't able to achieve it. RegardsDominik Schmid

Questions about how some HAL protocoles works in RTC

Hello ! I've been practicing how RTC works in STM32 Nucleo and I've used a code from this website tutorials.   void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc) { z ++; RTC_AlarmTypeDef sAlarm; HAL_RTC_GetTime(hrtc, &RTC_TimeStruct, FORM...

HSE "overclocking" ?

Heyho,anybody ever put more than 50 MHz from an active oscillator to an F767 / H723 / H735 HSE input?I need a VCO there, and I have a few with 51.2 MHz, so less than +5% over.I'm pretty sure it won't damage anything, but before I start (de-) solderin...
