Hi,
See below. Variables used in 12Blocks are available when using "code" blocks, you don’t need to do anything.

By default, all "io" pins are sampled at several thousand times/second. However, only the pins that are used with a "block" are graphed in "view pins". To see activity on pins that you manipulate with "code" blocks, insert a block that manipulates a pin with a block from the "pins" section. To sample at a faster rate- up to 20 Million samples/second, add a "quickly sample the IO pins" block to the beginning of your program.
