To transfer your working Simulink model for use with Simulink Desktop Real-Time, especially for serial communication with an IMU, you'll need to replace or adapt any blocks that are not supported in real-time environments, such as the Serial Receive block. The Packet Input block is a viable alternative for this purpose. It's crucial to correctly configure this block, including setting up the header correctly to match your IMU's data packets and ensuring the payload size is accurately defined. Additionally, using FIFO blocks for buffering can help manage the data flow, but you must ensure these blocks are configured with the correct size and data type to handle your IMU's output.
The "Dot indexing is not supported for variables of this type." error suggests an issue with how data structures are accessed or manipulated in your model, possibly within MATLAB Function blocks or in the way you're processing the serial data. Addressing this will likely involve reviewing and adjusting any custom code or data handling logic to ensure compatibility with real-time execution constraints.
