Good evening, I'm trying to interfacing a MEMS microphone MP34DT05TR in our board using interface SAI1 (SAI1_CK1 on PE1, SAI1_D1 on PD6). To get a faster result (I hoped!!) I used the cubemx to configure the interface and starting code. I see the cl...

Hi, We are using a STM32H745 in our project. Over the past few days, I've been wasting a lot of time figuring out why RTC has a major error ... it always runs slower than it should. To be sure we tried to used the crystal and the capacities present i...

Hi everyone,I recently revamped a product with a STM32F427 with a new STM32H745. Both cards have an external RAM of 16Mbyte. In the STM32F4 the data bus is 16bit width while in the SRM32H7 the data but is 32bit width. Both cards are set to go to the ...

Hello, I'm using a stm32h745 on my new board with an external 32768Hz quart and setup RTC at startup as follow (using LSE):HalErr_tError HalRtc_Init(void) { HalErr_tError zError = HalErr_eNoError;   /* Configure RTC prescaler and RTC data regis...

Hi to all,I need to send on every TIM interrupt a packet stream to SPI1. I can't use the HAL_SPI_Transmit(...) because it is blocking....so I need to use the DMA but not in circular mode.I can not use the synchronization of DMA with lptim using DMAMU...
