Description

PCB replacement for 2n Entrycom IP Uni doorbell. It will have 2 buttons with RGB background LED light and a speaker for PCM WAVE playback.

Hardware

M0dularis+ is used as base-controller.

Solder-Jumper configuration:

  • IO3: SJ for A0
  • IO2: D10 or A2
  • Application connector: 5V
  • Frontend connector: 5V
  • I2C (on IO0/IO1): PullUp

Software

The software enabled the user to fully have control over the buttons. One idea ist to have multiple states for the buttons. For instance

  • Default (white background light): Rings the bell
  • Postman (yellow background light): Ringing the bell will playback a wave file, telling where he can put the package that you are waiting for. Additional things can be triggered by calling a KNX GroupAddress, f.i. open the garage door half a meter so safely store the package.
  • ...

Open Questions

  • how to get files onto the SPI flash?!
