Hi,
I’m working with a data logger that sends measurements over a USB serial interface. I’d like to read the data using Simulink’s Serial Receive block, but I’m running into a problem: the block requires a fixed message length, while my measurements vary in digit count, so each message can be longer or shorter.
I’ve tried setting a maximum data size, but then the block misses the terminator since it relies solely on the fixed length. I’ve also experimented with a smaller fixed size in non-blocking mode, buffering incoming bytes and then parsing complete messages—but approaches that i tried introduce delays that are unacceptable for my application.
I’d appreciate any suggestions or solutions to handle variable-length serial messages in Simulink without significant latency.Hi,
