For anybody in the DIY community that is interested in building or collaborating with me to build their own foot controller. My prototype boards are working great and I am designing the next stage of my PCB for a DIY foot controller for the AXE III. Anybody that may be interested in a PCB board let me know and I can discuss details and add you to my order. These boards are 95% SMD. I can upload images later.
Specs so far:
2 X SAMD21G18 Micro Conrollers (Arduino based) (one micro is 100% dedicated to reading the footswitches)
SD Card slot(just because)
16 Foot switch inputs
16 NeoPixel 5mm LEDs
Nextion or 4DS serial driven display(touch screen optional)...up to 7"
Up to 3 amps of 5V onboard power(determined by external power supply) for display screen and LED's
9V power input, 5V buck convertor and 3.3v step down; board can also be powered over USB during development process. LCD may need external power. Jumpers available for this.
WinBond SPI Flash 32Mb
Midi In/Midi Out
SPI or I2C will be available for scribble strips but not currently standard due to the number of CS needed(a problem to be solved with a plexor or third micro later if needed)
I am rapidly building out the firmware.
