| Developer | Alexander Christian |
| Status | In Development |
| Microcontroller/Board | M0dularis+ |
| KNX connectivity | MicroBCU |
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 (SJ) configuration:
- IO3: SJ to A0
- IO2: SJ to D10
- Application connector: SJ to 3.3V
- Frontend connector: SJ to 3.3V (but is unused)
- I2C (on IO0/IO1): PullUp
* = PWM capable
# = INT capable
24V from yellow/white bus connector -> LM2596 step-down buck converter module -> 5V supply voltage for amplifier + LEDs
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?!
-> see filetransfer via Bus PoC
