Hello,I have developed my own board using the STM32H723VG and two equal sensors connected separately via SPI1 and SPI2.I have underclocked the MCU to 300MHz. The SPI clock is 48MHz while the communication frequency for both sensors is 24MHz. As CS I ...

Hello,after TDKs response I found a workaround for the issue. I simple send one dummy byte while I havent toggled the CS pin, before sending my data, to "wake" the spi peripheral. Now it works. It is good enough for sensor setup.Thanks everyone for y...

Hello,thank you for your comment and idea.The sensor is the ICM-42688-P. I have already worked with that sensor using the same MCU but used just SPI2 for one sensor. I had no issues with just one sensor. I will have look whether SPI1 has such a featu...

Hello,thank you for your comment and idea. I will test using interupt and dma. Those modes would also be my prefered modes after set up of the sensor.

Sorry that was an missclick. It is not the accepted solution. Is it possible to change it afterwards?My comment was:Hello,thank you for your answere.- There is an SPI peripheral clock which is generated by an PLL. The communication speed is divided d...
