The LCD2S-162FHA is a Serial LCD Character Display Module with a high speed SPI/I2C serial bus. The LCD display is a 2x16 character FSTN display(better contract than standard TN and STN) with an Amber LED backlight, and is RoHS compliant. A LCD2S-162 is soldered onto the back of the LCD display. It enables the LCD display to be controlled via an I2C or SPI serial bus. The contrast and backlight are software controlled, and can be set to 254 levels.
The LCD2S-162 includes a 4x4 (16 button) matrix keypad encoder with software debouncing. A keypad with up to 16 buttons (4 rows by 4 columns) can be added to the display via a standard 10 pin, 2.54mm header. Our 12 button or 16 button keypads can be used, and can be connected to the LCD2S-162 via the CAB16RIB150 ribbon cable. When using the I2C serial bus, an interrupt line will be activated when a key is pressed, informing the user that there is key data to be read. Alternatively the LCD2S-162 can be polled to see if it has any pending keypad data.
The LCD2S-162 also has 5 user configurable, general purpose inputs/outputs. Two of them can deliver up to 1000mA each, and have protection circuitry for driving relays.
The LCD used must supports 4 bit mode. All 16x2 Character Modules sold on our site support 4 bit mode, and nearly all commercially available LCD Character Modules support it too. The LCD2S-162 has a high speed SPI/I2C serial bus. For convenience the I2C and SPI signals are available via a Micro Match type connector, and a standard 2.54mm, 2x6 row pin header. Most new Modtronix SBC boards have Micro Match connectors, and can be connected to the LCD2S-162 using these 150mm or 300mm cables. Or, the CON-MICMAT6-MW Micro Match connector can be used to create a custom cable.
A 2-way DIP switch is used to configure the unit for SPI or I2C operation (3 different addresses). See our forum for many I2C, SPI, Arduino and other code examples.
