<p>Tom: /* Wait for incomming data (slave mode) */</p> <hr /> <div>[[Image:Block_SPI_Input_Output.png|thumb|rght|Block SPI Input/Output]]<br /> Input-Output Driver for SPI module<br /> <br /> The SPI Input-Output block can be configured as an input for SPI data, as an SPI output, or as both Input-Output. The SPI pin can be disabled after reading or sending data allowing the pin tu be used as a digital output (usefull if weird protocole is used)<br /> <br /> =Dialog Box Parameters=<br /> [[Image:Block_SPIInputOutput_DialogBox.png|thumb|right|450px|SPI Input Output Dialog]]<br /> ==n° SPI==<br /> SPI used<br /> <br /> ==SPI Input==<br /> If checked, SPI data will be read This add one output to the Simulink block.<br /> <br /> ==Wait for previous operation to finish, and Reset before Read==<br /> Wait for previous operation to finish, and Reset before Read<br /> <br /> ==SPI Output==<br /> When checked, SPI data will be written to the SPI pin. This add one input to the Simulink block.<br /> <br /> ==Special SPI==<br /> Allow to disable SPI pin function and to use theses pin as digital input/output.<br /> The choices are :<br /> *Always Enable<br /> *Disable After block execution<br /> *Re-Enable before block execution<br /> *Re-Enable Execute and disable<br /> <br /> ==Data Length==<br /> 8 or 16 bits. This option is set in SPI Configuration block<br /> <br /> ==Wait for incomming data (slave mode)==<br /> Stop execution of other blocks while no data are received<br /> <br /> ==Block Ordering Input / Output==<br /> Create one input and/or output port on simulink. This port is just used to set the order of execution between severals blocks. You want for example inside one time step set a pin to its high value and to its low value just after (create a glitch). You will used two blocks digital output, but they should be activated in a certain order. Connecting the first block to the second one (temporaly speaking) will allow to respect the execution order you desire.<br /> <br /> ==Status==<br /> Provides information like bit rate and status</div>
