flowcode variable and W register

[elecrobot]

Hi

consider i am using a calculation block in which i am equating a variable called SPEED = 127. Then I have a macro which calls a subroutine which is in some other C-Code block. I want to transfer this value of SPEED to W register. How can i do that. Thanks. (Please note i am using Flowcode V2).

Hello Electrobot

In C code you can call Flowcode variables by capitalizing the name and adding the prefix FCV_.

For example Flowcode variable count becomes C variable FCV_COUNT.

If you are using assembler to transfer the C variable then you will need a further _ prefix so the variable name becomes _FCV_COUNT in assembler.
