New Tutorial related with direct connection setup between Raspberry Pi board and MPDM v4 AC dimmer board.

Part 1: General view, wiring and hardware setup :

What we will need:

- MPDMv4 Universal AC Dimmer - available also on Tindie Store !
- Raspberry PI 2 Board
- Domoticz
   Latest available, on a Raspberry PI 2 Board install :  
     sudo curl -L | bash



1. PIGPIO library for Raspberry PI install script:
sudo rm -rf PIGPIO
make -j4
sudo make install
save it in the choosen directory for your PIGPIO library as "" and run also command:
chmod 775

2. Testing script:
#!/usr/bin/env python

#*** MPDMv4 Universal AC Dimmer PWM Example  ****************
#*                                                          *
#* This demo is using RPi2 GPIO18 (header pin 12)!!         *
#*                                                          *
#* Wiring table:                                            *
#* MPDMv4      Raspberry PI 2                               *
#*   VCNT  ->  GPIO18      - header pin 12                  *
#*    GND  ->  GND         - header pin 6                   *
#*    VCC  ->  VCC (+3,3V) - header pin 1                   *
#*                                                          *
#*                                *
#*                                                          *
import pigpio


pi = pigpio.pi()

if pi.connected:
   print("Connected to pigpio daemon !\n")

dm = 0
while dm < 860:
    dm = input("Enter Dimmer Value: ")
    dm = int(dm)
    pi.hardware_PWM(GPIO, 5000, dm*1000) # 5000Hz dm*1000% dutycycle

print("\nOut of range. Exiting...")
pi.hardware_PWM(GPIO, 5000, 860000) # 5000Hz 95% dutycycle

save it as "" in the PIGPIO folder generated after the full install is done.

Next time: Domoticz setup & configuration and Dimmer testing.
