Blaze Display Technology Co., Ltd. | Updated: Oct 28, 2015

【R&D Department of Blaze Display】Have you ever tried to deal with the I2C/SPI LCD interface before? If you haven’t, then you might want to test this out by your own!

It’s a lucky day to you, as today you’re going to develop an I2C LCD interface, which it’s allow you to connect an LCD to a microcontroller with only two simple wires!

You will think it’s a useful tool, if you like more pins to be available for another use, which a normal LCD interfacerequires a minimum of six pins or you would like to


make a control panel!Basically, with this I2C/SPI LCD interface you can only use two wires from your microcontroller and use up to seven I2C LCD interfaces on the same I2C bus. Furthermore, you also can be easily wire a five button input pad, example like a control panel and free up your serial port for other use with this I2C/SPI LCD Interface.

The great thing about the I2C/SPI LCD interface is it can be used with the Basic Stamp, any Arduino, Microchip PIC or any other microcontroller, which has been built in or a bit banged I2C interface.
