Hello;

I'm working with the Tiva C launchpad and Embedded coder for Energia, and the Serial Transmit only send unit8 data and Ascii format, so if I'm receiving a value of 123 from a sensor, and i try to send by serial I will receive in the other side a {, because it's the symbol for 123.

I need to create a substitute of the Ascii coder (because doesn't work with code generator. I tried making a C code but when i tried to read the array with coder.ceval I can't import arrays.

So my last option is to make a S-function to make the process of Sprintf, but in the output parameters i can't find the char or string option, so I'm thinking that I will not make with this tool.

Do you have some idea to make that?

Thanks
