SIMPL Crosspoints Best Practices

When I started Crestron programming in 2010, you had to take two classes. One covered almost the entire Crestron catalog. All I can remember is my eyes glazing over after a couple days of that. We might have built a touchpanel layout, too. The second class actually got into SIMPL programming, but we only covered button presses, feedback, interlocks, and maybe a toggle. It was fairly basic, but it was enough to get started programming Crestron systems.

After passing the exam at the end of class, they told us to go program systems for a year then come back and take the 201 class.

SIMPL Module Best Practices

When I started programming Crestron systems, there were two other programmers on my team. One was a senior programmer who had been doing it for years already; the other was a junior programmer who had been doing it for a year maybe? I feel like I fit into the middle slot between them quite nicely. So, I tried to follow the senior guy’s example and help the junior guy out when I felt that I could.

The workflow I picked up from the senior programmer was:

Copy-and-paste the previous program you worked on and only change the bits needed for the new system. 90% of the code is probably going to be the same anyway.
Don’t jam ANY signals together, always buffer them or use an OR.
Never hide program logic inside of a module.

I can already tell this is going to be a divisive post because of how different people treat user modules. I want to present 3 modules in this post, talking about why they were written, how they evolved, and why they were the best approach.

SIMPL Best Practices

I recently received an email asking if I could document some of the things I wished I had known when I started Crestron programming. I didn’t touch Crestron until the twilight years of the 2-series (2010), but it was thankfully a solid platform to learn SIMPL Windows on. I had several years of AMX under my belt, so at least SIMPL+ wasn’t strange to me.

I’d like to write a few posts that explore how I approach programming now that I have a little hindsight. I’ll also reveal areas where I still struggle to find the best methods.

Crestron has a SIMPL Windows Best Practices guide that is useful. The release notes also contain some good rules to follow. I’ll try not to repeat what’s already stated there.

Let’s dig in!
