 Flowcode is designed to allow those new to microcontroller programming to design programs with little knowledge of other programming languages. However it is possible to embed code written in other languages into Flowcode programs. Programs written in C and Assembly code can be embedded in Flowcode using the Code icon. This means that it is possible to take complex programs (you will find lots of programs on the internet) written in C or assembly and embed them into your designs.

-Enter any C code you wish to include in the flowchart. The C code is not checked by Flowcode but is passed straight to the C compiler when the flowchart is compiled. It is important to verify that the C code entered is correct, as syntax errors will cause the compilation of the whole flowchart to fail.
