I measured on working original board with ST7036i controller , 5V Vdd :
V0 pin = 3,82V (voltage from a divider with 2 resistors)
SDA = 150 ohm resistor between PIC pin and SDA LCD pin
SCL = to PIC pin
SDA and SCL = 1k to 5V
RESET = to PIC pin and 1nF capacitor to GND
RESET pin is all time to HIGH

A question : SDA and SCL pins from LCD must connect with SDA and SCL pins from PIC or I can connect to any pins pic ?
