# The code implements a trigger-based laser alternation using Moku:Go, where a falling edge on the camera's fire pulse initiates alternation between OutputA and OutputB. The process involves setting Trigger, OutputA, and OutputB to 0 or LO\_LVL after a certa

Here the linke to my simular question.

> Hi hanklong, It is good to know. But the problem I have remains. Maybe it is an understanding problem on my side when I run a Clk process. 1.) clk is the internal clock of the Moku Go box right? If this is the case then the individual processes are run in MHz frequency or ? so it should be possible to count the number of times in which the signal in Inputs 0 can be used as an If Else condition?
