Controller Test (w/ Script)
How to test Cronus Zen and controller functionality while also teaching you how to program scripts at the same time 🙂

When testing, setting up, or gaming on a PC, make sure the CONSOLE micro-USB cable, and PROG mini-USB cable are both connected at the same time.
If using an Xbox controller, set Zen Studio > Device > Output to AUTO and connect the controller to A1 - or if using a PlayStation controller, set Zen Studio > Device > PS REMOTE PLAY to enabled and also connect the controller to A1, the PC will correctly detect all PlayStation-only outputs, such as Adaptive Triggers, Touchpad, Gyroscope, and Accelerometer. It's that simple!

Zen Test Script
Here's a fantastic test script written by popular Cronus Community Moderator and GPC script expert, TaylorDrift21. It puts the Cronus Zen and your controller through every possible test so you can see what's working, or what isn't.
Requires Zen firmware and Zen Studio .
Tests include:
- Controller Tests (both Zen Input and Windows Output)
- Device Monitor Repeater (View Live Input Values)
- Button Tests
- Touchpad Tests
- Stick Tests
- Trigger Tests
- Gyroscope/Accelerometer Tests
- Rumble/Vibration Tests
- Battery Test
- Equipment In Use
- Led Tester Viewer
- Zen Calculator
- Ascii Viewer

Open Zen Studio to download, compile, and then program the Test Script to an available memory slot.
1️⃣ Select the Library tab 2️⃣ Type 'taylordrift21' in the search box and click the magnifying glass 3️⃣ Look for the script called 'Cronus Zen Controller Test GPC 32bit' and click the download button 4️⃣ The script will automatically download to the Compiler in Zen Studio.


5️⃣ Press F5 to Build & Run the script (or select Compiler > Build & Run from the menu). This will send the script directly to your Cronus Zen's Virtual Memory without programming to a physical memory slot. It will show in Device Monitor as Slot 10.
