[valvo]

How can I pass a value in the W register to a flowcode variable ? is it possible to have a program with subroutines in an ASM block ?

regards

Hello

Yes it is possible to create assembler subroutines, data on this should be in the BoostC manual located in the Flowcode V3/BoostC folder.

You can pass the W register value to a Flowcode variable by doing the following.

Flowcode byte variable named "flowvar" would become "FCV_FLOWVAR" in C code and "_FCV_FLOWVAR" in assembler.

Bit fussy on assembler but here goes.

asm
{
movwf _FCV_FLOWVAR
}
