Simulink - Serial Receive - Header
显示 更早的评论
Hey,
I'm reading serial data from a Interial Measurement Unit and dont know how to define a header properly. One frame is 56byte long (with 48byte of data). On the picture you can see the Block Parameters on the left and the Data on the right. The first 2 bytes (255 2) are the header, ending is 3.
I don't know the synatx to define the header, when i simply type 255 into header, i get only zeros for data.
Thanks for helping!

Header Specify data that marks the beginning of your data block. The header indicates the beginning of a new data block and the simulation will disregard data that occurs before the header. The header data is not sent to the output port. Only data that occurs between the header and the terminator is sent to the output port. By default none or no header is specified.
Anything entered in the header is treated as a character. If you want to specify numbers, you need to use the corresponding ascii characters for them. For example, to specify [40 41], you can enter () in the field. Note that single quotes are also treated as characters. You can use the corresponding ascii characters for the numbers between 32 and 126.
