Posted on July 06, 2017 at 19:06Hi. I have noticed that STM32CubeMX has some limitations when configuring a USART for synchronous mode. I am using a STM32F413RGTx running at 100 MHz.I am configuring USART3 for synchronous transmit/receive (pseudo SP...

Posted on April 09, 2018 at 19:21Fair enough. What would the correct solution be then? You could keep the OP's modification, with a speed penalty. But that wouldn't work for HAL_SPI_TransmitReceive_DMA. You could introduce another set of functions w...

Posted on April 09, 2018 at 17:41Why is this a defect? If you configure for 8-bit operation, then it will not perform unaligned memory operations. If you configure for 16-bit operation, you better be sure to provide an aligned address. Am I missing ...

Posted on April 09, 2018 at 16:16What you did made everything work, but it did not solve the underlying problem. You have your SPI peripheral (and HAL) configured for 16-bit SPI data. The right way to resolve this issue is to A) pass an even address...
