https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/MBDT-Can-t-update-SPI-message-using-StateFlow/m-p/1599133#M8026 <P>I'm working with the MPC5744P and trying out Stateflow in addition to the required #MBDT&nbsp;software. I'm interfacing with an SPI module and trying a sequence of steps to confirm proper communication and that a register write did in fact complete. It looks really nice in stateflow, but I couldn't get the input/output data to take effect on the SPI message. When I built a if statement version it seems to be working. It's not as pretty though, so I really hope I'm just missing something. Attached are screenshots of my working and non-working versions of the same code.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="top_level.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/210904i869D032380266E72/image-size/medium?v=v2&amp;px=400" role="button" title="top_level.png" alt="top_level.png" /></span></P><P>^ Top level</P><P> </P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="working_SPI.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/210905iCCE6E8B445507649/image-size/medium?v=v2&amp;px=400" role="button" title="working_SPI.png" alt="working_SPI.png" /></span></P><P>^ Working SPI trigger</P><P> </P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="non_working_SPI.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/210906i3FC306D8049FA922/image-size/medium?v=v2&amp;px=400" role="button" title="non_working_SPI.png" alt="non_working_SPI.png" /></span></P><P>^ Non working SPI trigger </P> Tue, 14 Feb 2023 23:08:14 GMT DN_at_Rix 2023-02-14T23:08:14Z https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/MBDT-Can-t-update-SPI-message-using-StateFlow/m-p/1599133#M8026 <P>I'm working with the MPC5744P and trying out Stateflow in addition to the required #MBDT&nbsp;software.
