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...

STM32H7R/S lines: 1st STM32 with bootflash and on-the-fly encryption

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...

How to configure OctoSPI in Quad mode with PSRAM for memory mapped write access? Getting Hard Fault (FORCED, IMPRECISSERR) when write is attempted.

Hi there, I trying to configure octospi on STM32H7A3 to work with LY68L6400 PSRAM via quadspi.I have followed AN505 and managed to init, write and read from the memory successfully in indirect mode.Now I am trying to map the PSRAM to memory. I can re...

May I know if there's a new qualification of MSL for STM32F devices from year 2021? particularly on STM32F100. Thanks!

SPI data transmission

Using STM32f3xxx series & using SPI2.I wanted to transmit 32 bits data at atime, but in APIHAL_StatusTypeDef HAL_SPI_Transmit(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size, uint32_t Timeout) pData is fo r uint8_t.how to transmit uint32?

I'm going crazy, look at the photos: if I move the SWD CLK connection in one point of the breadboard the connection works, in another it doesn't! The chip is a STM32L412KB, I tried to replace it but nothing! I also replaced the ST-LINK but nothing yet.

Resolved! Hi! I m using the uC STM32G431 to drive a H-bridge. I saw that the reset value of GPIOx_PUPDR for PWM pins is 0 which means they are in state "no pull-up, pull-down", so they are floating. I m afraid that they could activate the driver of MOS. What to do?

Multiple ADC sample with different frequency interference

Hi,everyone.I'm use NUCLEO-L496ZG platform.ADC1 sample at a frequency of 5M,ADC3 sample at a frequency of 12.8K(PWM trigger).when only run ADC3,ADC3's waveform is normal.when ADC1 and ADC3 run at the same time,ADC3's waveform has a lot of interferenc...

Can not able to transmit continuously

Hi,i am transmit data through can protocol in stm32f103 controller in the while loop and i am doing doing adc and display data on 16x2 lcd so i found that doing this my can transmit is transmitting only 4-5 times amd then stop so i want to ask what c...

Resolved! Hi, My signal is 50Hz and 175Hz (about 20% of 50Hz), Sampling 25600 samples/Sec. Implemented with 4096 pointFFT. I am getting 50Hz spectrum @8th location and expecting 175Hz at 28th location. but it is distributed to 24 & 30. other spectrum shows zero

Can any one help me on this. thanks in advance

Timer in Encoder Mode Interrupt via Output Compare

I know, I'm repeating an age old question, but has there been any updates on generating an Interrupt when using a Timer in Encoder mode? I know, that the Interrupt doesn't fire in Encoder mode, but I read in this one thread, that it's somehow possibl...

Ordered MCUs have shorted pins

Hello. I recently purchased STM32F405RGT6's. However, out of package and on all of the IC's that I received, I discovered shorts between pins 17 (PA3) and 18 (VSS), which I do not believe should be shorted. I have a few STM32F405RGT6's that I purchas...
