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 install.domoticz.com | bash


 
Software 

1. PIGPIO library for Raspberry PI install script:

rm pigpio.zip
sudo rm -rf PIGPIO
wget abyz.co.uk/rpi/pigpio/pigpio.zip
unzip pigpio.zip
cd PIGPIO
make -j4
sudo make install

save it in the choosen directory for your PIGPIO library as "install.sh" and run also command:

chmod 775 install.sh

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                   *
#*                                                          *
#* tech@esp8266-projects.com                                *
#*                                                          *
#************************************************************ 

import pigpio

GPIO=18

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
pi.stop()

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


Next time: Domoticz setup & configuration and Dimmer testing.

WIFI Dev Board for Home Automation - Part 2

This is Part 2 of the Wifi Dev Board for Home Automation series. For general presentation and hardware description please take a look also at Part 1 of the series


MPRSx8 Board is available also on Tindie store: https://www.tindie.com/stores/nEXT_EVO1/







What we will need:

• MPRSx8 Board
• ESP8266 ESP-12E module loaded with ESPBasic firmware
• For programming we will use the brilliant ESP Basic interpreter Web editor

Software implementation:

As this time we will talk about the Software side we will design a very simple driver for our board that will include also a interactive Web command interface for the MPRSx8 Home Automation Dev Board Relays.

To keep things simple, we will just add in our Web Interface 8 ON/OFF Buttons and one general OFF one, from where we can turn ON/OFF all the Relays switches. 


1. Main Program

cls                       ' clear interface
let address = 56  'PCF8574 I2C Address

i2c.setup(4,5)      'choose your I2C bus pins

i2c.begin(address)
ss = 0 xor 255      'XOR - Bit masking for the desired I/O pins
i2c.write(ss)
i2c.end()
button "x1", [5]    ' Button for Relay 1
button "x2", [6]
button "x3", [7]
button "x4", [8]
button "x5", [1]
button "x6", [2]
button "x7", [3]
button "x8", [4]    ' Button for Relay 8
button "OFF", [9] ' General OFF for all the Relays
wait

2. General OFF for all the Relays subroutine

[9]
i2c.begin(address)
ss = 0 xor 255 'XOR - Bit masking for the desired I/O pins
i2c.write(ss)
i2c.end()
wait

3. Subroutines for each Button

[1]
i2c.begin(address)
ss = ss xor 1   'XOR - Bit masking for the desired I/O pins
i2c.write(ss)
i2c.end()
wait

[2]
i2c.begin(address)
ss = ss xor 2
i2c.write(ss)
i2c.end()
wait

[3]
i2c.begin(address)
ss = ss xor 4
i2c.write(ss)
i2c.end()
wait

[4]
i2c.begin(address)
ss = ss xor 8
i2c.write(ss)
i2c.end()
wait

[5]
i2c.begin(address)
ss = ss xor 16
i2c.write(ss)
i2c.end()
wait

[6]
i2c.begin(address)
ss = ss xor 32
i2c.write(ss)
i2c.end()
wait

[7]
i2c.begin(address)
ss = ss xor 64
i2c.write(ss)
i2c.end()
wait

[8]
i2c.begin(address)
ss = ss xor 128
i2c.write(ss)
i2c.end()
wait

In the Web editor interface Save your program as "test_MPRSx8_1.bas" and Run it.

If all OK the result should look as below:

If you want your program to start automatically at reboot/power ON then just Save it as "default.bas" and also from Settings Tab enable the "Run default.bas at startup".

Be aware that at start-up/reboot, it is a delay before your program will start automatically.
