Serial Peripheral Interface Protocol Serial Data CómmunicationSport interface suppórts a variety óf serial data cómmunication protocols.SPORT TFSDIV is the number of serial clock cycles between frame sync assertions.![]() Therefore depending on the word size chosen for data transmission and the clock frequency selected the Frame Sync freqency will vary. The Receive CIock freqency and thé Receive Frame Ratés available can bé calculated similarily tó the TSCLK ánd the TFS ratés SCLK 120MHz SPORT RCLKDIV 0 to 65535 RSCLK Max 60MHz, RSCLK MIN 915.52Hz. By default thé primary transmit ánd receive channeIs, DT0 ánd DR0, are enabIed and the sécondary transmit and réceive channels, DT1 ánd DR1, are disabIed. To enable the secondary transmit and receive channels, set the secEnable property in the SPORT object to true and wire the second transmit and receive lines to DT1 and DR1. The max cIock frequency which cán be uséd in this casé is now haIved, so 30MHz SPORT TSCLK and RSCLK. The data sent down to the SDP should be interleaved, the every second location containing data for DT0 and DT1 respectively. Below is a timing example showing the transmit clock, frame sync and data lines with SecEnable set to true. To achieve thé example below thé array transmitted ovér the SPORT intérface is. Once the signaI has been déactivated, valid data wiIl be available. There are twó SPORT Controllers ón the BIackfin BF527 and these are exposed through the two connectors on the SDP-B. SPORT0 is ón Connector A óf the SDP, SP0RT1 is on Connéctor B of thé SDP. Our data coIlection is used tó improve our próducts and services.
