We are using the STM32H725IGT6 MCU. We are using 4 SPIs -> SPI1, SPI3, SPI4 and SPI6. We are able to communicate with the SPI slave on the SPI1, SPI3 and not able to with SPI4 and SPI6. We are able to see the SPI4 clock on the SCK pin, but there is n...

The voltage for the STM32H725IG MCU available in our application - 3.3V.This MCU has both SMPS and LDO.According to the power consumption, SMPS consumes lesser power.But we are confused about what would the benefit of choosing SMPS cascaded with LDO ...

I interfaced LSM9DS1 with TI micrcontroller TMS320F28035 with I2C protocol. The LSM9DS1 is SDO_A/G pin is pulled low, so that it can be addressed with 0x6A. But what I observe is..Whenever I power the board up, it does not respond with 0x6A and respo...
