IMPLEMENTED SO FAR
- Support for 4x20 LCD Display and large number display
- Brightness and contrast adjustment with remote
- (OPUS/Wolfson WM8741) DAC volume control: remote and rotary encoder
- (OPUS/Wolfson WM8741) DAC random filter selection 1 to 5 with remote
- (OPUS/Wolfson WM8741) DAC upsampling selection (L, M, H -this is the OSR setting)
- I2C level shifting (5V to 3.3V)
- Optimized power-up sequence
Two Modules Together
I salvaged (from ethernet routers) some surface mount LEDs for the Tx/Rx. Yellow and Green. The Freeduino board does not have the automatic power selector, I replaced the jumpers with a switch. In order to reuse the traces in the red board, I've had to reroute certain signals and cut a couple of traces.
