COG FSTN 240x64 dot matrix graphic lcd module, 24064 lcd display
FSTN monochrome graphic lcd module 240X64 graphic popular 24064 graphic lcd, oksmart advantage : we have our own lcd glass line, customizabble dimention and backlight and also connector.
The OKM24064-01 display has an integrated microchip that manages this type of communication, and then all of the input and output information are limited to only two PINs (excluding power supply).
I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V.
