/**
|
|
* The 2004 LCD should be powered with 5V.
|
|
* The next LCD pins RS,D4,D5,D6,D7 have internal pull-ups to 5V and as result the 5V will be on these pins.
|
|
* Luckily these internal pull-ups have really high resistance and adding 33K pull-down resistors will create
|
|
* simple voltage divider that will bring the voltage down just slightly bellow 3.3V.
|
|
*
|
|
* This LCD also has buttons that connected to the same ADC pin with different voltage divider combinations.
|
|
* On the LCD panel there is internal pull-up resistor of the 4.7K connected to 5V.
|
|
* Connecting another 4.7K pull-down resistor between ADC pin and the GND
|
|
* will result in scaled values for voltage dividers and will bring them down to be always below 3.3V.
|
|
*
|
|
* For 2004 LCD to work with 3.3V board like Arduino DUE the next required:
|
|
* Pull-down resistors of 33K between each of LCD pins RS,D4,D5,D6,D7 and the GND.
|
|
* Pull-down resistor of 4.7K between ADC_KEYPAD_PIN and the GND
|
|
*
|
|
* All these modifications will still work with 5V based boards but require proper scaled ADC values
