02. BUILD 32. Put on the caps of the buttons. 33. Place the front panel on top, tighten the jack and pot nuts, make sure that everything is nice and vertical. Adjust the LEDs in the holes as you like. 34.
03. UPLOADING SOF T WARE 1. Download the firmware from the Antumbra website. 2. Connect your AVR ISP device to the 6 pin ISP header on the module. Pin 1 is marked with a dot. 3. Use an AVR programmer, like AVR ISP MKII with for...
