Convert ASCII-characters to double in simulink

I'm receiving serial inputs to a simulink model in the format ASCII-characters (in dec). For example, I'm receiving 49 46 53 which corresponds to the number 1.5.
Which is the easiiest way to convert 49 46 53 to a 1.5 (double) to be used in the Simulink model?

The Matlab-command native2unicode performs the conversion but I can't use this command in an Embedded Matlab function and build my model to a platform (in my case a dSpace microautobox). Is there a simulink model block which performs this operation?

Thank you,
Erik

Anyone got a hint about this one?

Hi Erik & Minal,
i am having the same issues with the Uni conversion. i am using dSPACE as like you. Did you guys find any solution to the problem. If yes Please do let me know about it.

hey guys,
i found a small solution to my problem.
all though its not 100% complete but to some extent....it works
making use of data type conversion & Embedded matlab function.

i still dont have the correct 100% solution, but this is atleast 70% working..

Regards,
Piyush

Hi, everyone

I had this problem and solved using a block from xPC Target Toolbox.

Under xPC Target Toolbox, go to RS232 and look for the block "ASCII Decode".

It will convert you uint8 vector to double according to a format string like: %d\t%d\n (for example, if you have a uint8 vector that represents two integers separated by 'tab').

I hope this helps.

Hey Piyush,

I am having the exact same issue as you had (reading encoder data in dSPACE) and it would be really helpful if you can share your 70 % working solution for this.

Thanks a lot for any help.

With Regards,
Madhu

Any chance you could share you solution to the parsing, trying to do a similar thing by bring in GPS NMEA strings and need to parse them on an MABII.
