I'm using a Nucleoboard with a STM32f103RB chip. I would like for a project to communicate with SPI protocol by sending frame of 9 bits. I've seen in the datasheet that I can configure the SPI datasize that way :
SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
SPI_InitStructure.SPI_DataSize = SPI_DataSize_16b;
But I would like to know if it's possible to use others size of frame (9,10,11.. bits).
Thank you for your help.
