Hi! Any instructions?

[manucontrovento]

Hello everyone! I own a Zoom R8 and I need to sync it!
I found this project.
How do I realize it?
Which arduino?
How will it connect with r8 and receive the pulse?
Could someone help me?
Thanks a lot!!

Hi!

Sorry for late reply! This is not one of the most active projects ever, but thanks for the first ticket! :) I really should have written this down when I made the project. Now I don't remember the details. But if you're still interested, I should be able to help out reverse engineering it a bit. Note that this requires some understanding in electronics and you need to figure out where to best find spots for soldering your wires. And I guess if your R8 still is on warranty, it will expire by just the thought of doing this.

First, you can use any Arduino of choice. I think I used a Nano as it fits nicely inside the shell of the R8, but use whatever you have. Secondly, looking at the code, in main/main.ino, you can set up which pins/ports to use. I used low level addressing because that is much faster than the Arduino functions for reading pins and writing to ports, but it is not as conveniently named.

You will need to refer to the pinout of the Arduino of your choice. Right now, I would need to spend a bit of time understanding what to connect where. I don't remember from top of my head the purpose of the line0 and line1 signals. Maybe they are not needed. The LED (named trig in the code), play (gate), stop and rewind buttons need to be connected to the corresponding PINs, and you need to add a jack or a lead to connect to your external gear, where trig and pulse need to be connected.

Once again, sorry for not replying in time, and also for the inability to help out in detail at this stage. Maybe you have already moved on to the next project anyway. :)

Hi @johansmolinski and thanks for your reply
I switched to a totally different gear sync system and I don't own the R8 anymore... Thanks anyway
