The motivation is to avoid chunking the data using on-chip RAM, and to shorten the transfer time. Is this possible? If so, how? My processor is a K64.</P></BODY></HTML> Thu, 06 Jun 2019 20:24:17 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/How-to-do-a-SPI-to-SPI-transfer/m-p/954965#M54864 jeffthompson 2019-06-06T20:24:17Z Re: How to do a SPI to SPI transfer https://community.nxp.com/t5/Kinetis-Microcontrollers/How-to-do-a-SPI-to-SPI-transfer/m-p/954966#M54865 <HTML><HEAD></HEAD><BODY><P>Hi Jeff, </P><P>I think this is possible.
