The UDP Receive block receives UDP packets from a UDP host. ... Simulink Coder Support Package for STMicroelectronics Nucleo Boards Description. The UDP Receive block ... If you simulate a model that contains the UDP Receive block on your host computer (e.g., Simulation > Normal), and send UDP packets to that model from a board, the data output emits a disproportionately large number of zeros. This is because Simulink software simulates the model as a free-running application with a shorter period than the real ... The Simulink Real-Time driver blockset for this module offers a composite Send/Receive block as well as low-level setup, send, receive, FIFO, status, and utility blocks. 4 independent serial ports Supports RS-232, RS-422 full-duplex, RS-485 half-duplex
