IIC / I2C / 1602 / TWI SPI interface LCD character module / electronic building blocks

Arduino IIC/I2C/TWI SPI LCD1602 LCD character (l blue) electronic building blocks

Description:
Serial LCD also have this section IIC and SPI interface, a switch can easily switch between the two.



As the Arduino fans and users with limited resources if the pin on the Arduino then anormal 16-foot LCD screen, it will be a very difficult thing, because once you connectthen you will find the screen can be used for other functions pin extremely rare. Now the problem can be easily solved, our latest development of the IIC (I2C) / SPI LCD1602 LCD character module can solve these problems, IIC (I2C) can be achieved only two lines of data communication. In addition, we are providing morechoice, you can easily switch through the onboard SPI and IIC in the switch between.



What good does it do? IIC is because the analog input pin A4 A5 shared, when youneed to use all channels of analog input can no longer use the IIC interface, this timeusing the SPI as the display can solve this problem. That SPI can be used as a standby interface, it is noteworthy that, although equipped with two interfaces, but the price is indeed a single function of the IIC LCD and the same. SPI functions tobe our customers an additional small gift.

Parameters:
1 support the IIC bus (device address: 0x20 on the bus if other devices withduplicate addresses, you can change the board by shorting pad device address)
2 SPI bus
3 1602 character LCD display (blue, green backlight optional)
