I need help with Simulink UDP Recieve and the Unpack blocks. I am using a C++ code to stream data from two sensors in our lab via UDP into a Simulink UDP block on the same computer. Each frame of my data contains 10 int_32 values. The first int_32 value is either a 0 or a 1 to indicate which of two sensors is the current frame associated with. The rest of the 9 are the payload data from the sensor.
After receiving the frames from the UDP packet, I also use a Display block to monitor the raw byte values. When I put the byte values in the Display block into a vector and call the char() function on the vector, I get the same signal frame that was sent from each sensor. However, the output from the Unpack block is made of some weird numbers. For instance, when I parse the outputs from the Unpack block into two – (1) sensor identity and (2) payload, the identity value switches between 8240 and 8241 instead of 0 and 1. The payload data is also made up of weird numbers not similar to the actual sensor data. A typical frame of raw data from the sensors appears as this: 0 76 -99 9863 -10 8 -1 184 -87 -56. Can anyone help me? NOTE: In the Unpacking block setting, the same problem using Byte alignment of 1 or 4.I need help with Simulink UDP Recieve and the Unpack blocks.
