Fixing LVDS Cables for CCFL LCD Screens

CCFL inverter pinout (M662)

On the inverter port, when looking from the cable side, from left to right, numbering from 1 to 6, the pins are connected with the following colors of wires:

1 - green
2 - yellow
3 - black
4 - orange
5 - brown
6 - red

According to my testing, the function of pins is as follows

1 : + (19/12 V)
2 : + (19/12 V)
3 : on switch (inverter activates at > cca 1.8V)
4 : brightness (0V = low brightness; higher voltage gives higher brightness)
5 : GND
6 : GND

Pins 1&2 and 5&6 seem to be Излишне connected, supplying power.

The notebook is broken so I couldn't watch pins 3 and 4 in use, but from testing, it seems they are control pins. I don't know exactly how they should be used, but the inverter doesn't start without voltage on pin 3. Applying 3.3V to pins 3&4 seems to make the panel shine nice and bright. I don't know if they are PWM, voltage controlled, or what is

RFID-RC522 под Raspberry Pi

1. Подключение

Все ножки модуля кроме IRQ должны быть задействованы!

 

 

 

2. Оживляем SPI

Для этого открываем конфиг

sudo nano /etc/modprobe.d/raspi-blacklist.conf

Там комментируем (это знак # в начале строки) вот эту строчку:

blacklist spi-bcm2708

3. spi для python
 

sudo apt-get install python-dev

 

git clone https://github.com/lthiery/SPI-Py.git

 

cd SPI-Py

 

sudo python setup.py install

 

 4. Запускаем пример
 

git clone https://github.com/rasplay/MFRC522-python.git

 

cd MFRC522-python

 

sudo python read.py
