Resolved! STM32U5 SAI in I2S mode + GPDMA

Hi,I have a board with an STM32U575 at the core.I'm attempting to set up SAI receiver in I2S mode, with 32-bit 48kHz sampling. See my configuration of SAI A below: I also want to receive the data continuously in circular mode via DMA (or GPDMA in th...

Resolved! What is USART CTS latency?

I am starting a product design tentatively using the STM32F072RBT6.I want to determine how soon the CTS input must go low to prevent the USART from transmitting the next byte.Even informed opinion would be appreciated; but a reference to documentatio...

Resolved! STM32L433 VREFINT_CAL Value

Hello,I'm trying to work with the ADC of the STM32L433 microcontroller. The Reference manual (RM0394) on page 448 it says : The following formula gives the actual VDDA voltage supplying the device:VDDA = 3.0 V x VREFINT_CAL / VREFINT_DATAWhere can I ...

Resolved! STM32H7 RM0399 Rev4 FDCAN Typos?

Looks to me like the FDCAN peripheral has a few registers that are marked 'r' when they are likely 'rw' in the RM. They are the registers that configure the size of the FDCAN messages. This isn't blocking my work; only thought the ST team should know...

Remote wakeup on STM32F0

Trying to implement a composite HID device on STM32F042 (or maybe STM32F072 as both Flash and RAM usage seem insane), starting from the MX mouse middleware. After much scratching around it's finally working as a mouse and keyboard and I now need to a...

DMA and Direct Mode

Posted on August 07, 2013 at 21:21 I'm confused about the FIFO error flag (FEIF) when I set up DMA for direct mode transfers. As I understand it, in direct mode the FIFO is disabled. But for some reason, if I enable the FE interrupt in the DMA_S...
