Hello I have a question when I work with SPI in DMA which flag can tell me when I finished sending My buffer? I understand that TXEMPTY it's not the correct one but I don't understand the different between TXBUFE and ENDTX. With which one I need to work when I work with spi in DMA? thanks chiko.
Or, in general, "If the datasheet does not contain the relevant information, then you obviously have to contact the device manufacturer"
The first step would be to visit their website and look for Application Notes, and Examples and other such supporting information.
Note that many manufacturers today divide their documentation into a "Datasheet" and a "User Manual" (specific names vary) where the "Datasheet" is just electrical parameters, etc, and you need to read the "User Manual" for details of registers, etc.
