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.

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...

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...
