New additions:
PIC16F628 based LCD display driver controllable via serial data input and with a 4 button command interface.
- Picture of the finished display
This is a serial data LCD display driver I developed to be used in conjunction with Jeff Keyser’s Wifi router webradio project. In order to get this display driver working together with the router, see the interface related shell scripts for the wifi webradio here.
The driver is laid out to hook up with a 2×40 LCD display but could easily be adapted to suit other displays by adding a scrolling functionality. Right now I did not add this feature due to the lack of such a display for testing.
The main features of this driver are:
- Works with common HD44780 based LCD displays.
- Serial Input, only 4 wires needed (Rx, Tx, Vcc, GND).
- User selectable baud rate (9600 or 19200).
- 4 Button – Interface with user definable message output and counter value output.
- User-programmable splashscreen message.
- User-programmable start message to avoid display from showing boot-time messages.
- All user definable parameters are programmable via serial port commands, no pic programmer required.
- User definable parameters stored in EEprom.

Midi-CV/Gate Converter with additional CC output
The key features:
- Low cost, part costs below 20E ( actually with the power supply it is more expensive)
- 8 bit resolution
- Midi Channel learn function by button press
- Midi Channel saved to EEprom and loaded at next startup
- Linear and Logarithmic CV curve implemented on microcontroller as a lookup table
- CV mode saved to EEprom and loaded at next startup
- Gate off via either note-off command(8xh) or by note-on with velocity zero
- Linear mode range: 8 octaves
- Logarithmic mode range: 3.octaves
- Modulation Wheel CC on second DAC output
- Positive supply voltage only, no bipolar power supply needed
