lcd_io_10
Using connection mode 10:
The LCD is controlled via I2C of a type 10 LCD 12C adapter. Use LCD_IO 10 for the YwRobot LCD1602 IIC V1 or the Sainsmart LCD_PIC I2C adapter. To use mode 10 you must define the I2C ports as normal in your Great Cow BASIC code. Then, define the LCD type, set the I2C_address of the LCD adapter and the LCD speed, if required. Finally, set the backlight control, if required.
Relevant Constants:
These constants are used to control settings for the Liquid Crystal Display routines included with Great Cow BASIC. To set them, place a line in the main program file that uses #define to assign a value to the particular constant.
