SCK Active during CS High

I'm making use of the STM32L433 and using SPI to communicate with a LLCC68 from Semtech.I've noticed that my SCK is active after my CS goes high.Is this normal behavior?Code Snippet for SPI Write:LLCC68_StatusTypeDef spiWrite(uint8_t* data, uint8_t s...

Bug in STM32CubeIDE, Version: 1.10.1, Build: 12716_20220707_0928 (UTC), regarding IRQ on DMA transfers with STM32F401

I have a small project which should generate an interrupt whenever a DMA transfer has completed. If I build the code for an STM32F411 then it works exactly as expected. If I build that same code for an STM32F401, which is within the same family as ...

Hi There, I have the SMBUS example code for STM32L4R5ZI-Nucleo. As per the spec this code should be fully compatible with STM32L496z-Nucleo. However, when I flash the example FW from STM32L4R to STM32L496 the SMBUS functionality does not work.

STM32F070 Standby Mode (Not waking up...)

I wanted to test the wakup pin on the stm32f070f6.I have set pin PA0 to SYS_WAKUP1 and gave it the user name "WAKE". Before the user while loop I call: HAL_PWR_EnableWakeUpPin(WAKE_Pin); HAL_PWR_EnterSTANDBYMode();To enable wakeup (I thought) and put...

The match interrupt on LPTIMx->CCRx is triggered when LPTIMx->CNT > LPTIM->CCRx - not on equal (=) as one might expect

On the STM32U5xx, ST decided to keep this interpretation of "match". It is present on other chips as well, see https://community.st.com/s/question/0D53W000004J0srSAC/stm32l0-lptim-generating-random-compare-match-interrupt-when-changing-compare-match-...

Dear Team STM32F437IIH6TR about this part,could you help me to provide the ECCN/CCATS FILE? We bought a batch of the goods, but the customs asked us to provide ECCN or CCATS documents before we could enter

CCATS copy of licensable item

In theory, you can use all 26 bit of the STM32U MDF in the CIC stage. In practice, I recommend to stay < 25 bit to avoid artifacts and saturation.

Interruption, but corresponding interrupt flag is not set?

Dear community,I am having a strange problem with the STM32L431.The ADC is set up for use with both the DMA and interruption. This is to de-interleave the adc results from 2 different channels, since there was problem with interleaved ADC results whe...
