Configuring OSPI in QSPI with Memory Mapped

I am trying to setup my STM32H725 to use serial RAM in memory mapped mode. The memory I am using is:IS66WVS4M8ALL RAM DatasheetI have used IOC to setup the OCTOSPI1 as a QSPI peripheral and mapped CS IO0/1/2/3 CLK from the uC to the RAM.I have tried ...

SPI read/write time calculation

Hello everyone.I'm interfacing my STM32F745IET6 (master) with an SPI device.I'm using SPI1 interface running at 50 MHz, I was wondering if there's some "rule of thumb" to calculate time needed (in terms of clock cycles) to write n bits over the bus. ...

SPI with Registers: Issue in Data transferring

Hello,I want to transfer data between NVIDIA Jetson Nano (Master) and STM32 (Slave) using SPI. On the master side, I am using spidev python library. On the slave side, I am coding using registers (without using HAL).I want to send and receive data co...

SPI slave transmit receive trouble

Hello,I am working with a STM32F446ZET6 and using it as an SPI slave.I use the function HAL_SPI_Transmit_Receive_IT function to receive 4 bytes of data.It used to work properly in our conception, for example when the master sends 0x12, 0x34, 0x56, 0x...
