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
Bought the DUEMILANOVE
It was on sale at NKCElectronics. The Arduino Mega was also released and it has 6 external interrupt pins, but it cost almost 3X what I paid. I guess I'll live with 2 interrupt lines for now.
