hi i use two spi and connect together spi 1 send(Full D Master) and 2 receive(Full D slave ) all in dmaif i change send buffer, in receive first array not change. it was first init that send dma uint8_t TXBuf[]={0,1,2,3,4,5,6,7,8,9}; uint8_t RXBuf[10...
What is the response for STM32H7 DFSDM in FastSinc mode?
The STM32H7 reference manual revision 6 gives the FastSinc response as:However this seems to make no sense. The first part is a normal sinc^2 filter, but the second part describes an impulse + delayed impulse, which results in a quite strange frequen...

Can the STM32L4+ RTC use an external LSE clock when in VBAT mode?
I couldn't find this mentioned in another thread, most discussion was based around LSE vs HSE & LSI. Basically, I'm wondering if we used an external 32.768 kHz clock with the STM setup in bypass mode, whether that clock could be used to maintain RTC ...
Receive SPI data from an unknown device.
Hi I want to communicate with a device that uses SPI, I want to grab data from this device but when it transmits a byte waits for an acknowledgment signal which is a positive pulse with 2us lent. So I should wait until it sends 1 byte of data, store ...
