Gate_Mod

Here’s the code (and schematics) from the AniModule Gate_Mod
This is NOT the original code that shipped with the First Batch.
This is a Firmware Update.
The Original code had a bug in the delay out section that did not allow it to rest at 0V.
That has been fixed in this new revision 🙂
All Gate_Mods that shipped after Mid August 2015 have the new revision installed.

You can copy/paste directly to your Arduino IDE.
it won’t compile unless you have Paul Stoffregen’s digitalWriteFast Library installed. There’s a little more about this on the Schematics / Code page.

There are pads for a 5 pin header at the bottom right of the ATMEGA328.
Installing a Header here facilitates an ICSP to use upload sketches directly to the Module without having to pull the IC.
From top to bottom the pins connect to the ATMEGA328:
VCC (I’m using +5V)
VSS (GND)
TX
RX
Reset

You can connect directly from an Arduino with the IC removed to program it or use a USB to TTL converter etc.
The VCC is connected to the Modules +5V via a diode so no need to fear for your USB port if you forgot to disconnect your -/+12V EuroRack PSU before you connected your programmer 😉

If you make changes to the code, improvements, or come up with something interesting to do with the Gate_Mod I’d LOVE to hear about it! Please take the time to register and post up in the comments! You can also catch me via email, or PM / Post on Muff’s or Electro Music or the AniModule FaceBook Page.
