Hi, i have a project here using an STM32U575RIT6Q with an external device i have connected throught the SPI interface.The microcontroller is at 160MHz using HSE with PLL. The SPI interface is at 40MHz with SPI mode 0, nss software and 8 bits per word...

Hi, this is new for me. im working with a project that includes an STM32U575RIT6Q controlling a device through the SPI3 interface at 40MHz with 8 bits per word, SPI mode 0, and the GPIO change speed at very high. The microcontroller is running at 160...

hi @urbito .Thanks for ur response. This specific code is for SPI in master mode.I am using the STM32U575RIT6Q micro in order to command some external slave devices.There are some cases where i need a long transaction in either transmit or receive mo...

Hi @ASchw.1 Thanks for the replying. I have tried the method u said. But sadly it did not work for me.The LL_SPI_Disable call resets the SPE bit to 0. i have added this.CLEAR_BIT(hspi1.Instance->CR1, SPI_CR1_SPE);Before each HAL_SPI_Receive. This bit...
