SPI_Glcd_Write_Char
SPI_Glcd_Write_Text
Prototype
void SPI_Glcd_Write_Char(char chr1, char x_pos, char page_num, char
color);
Description Prints character on Glcd.
Parameters - chr1: character to be written
- x_pos: character starting position on x-axis. Valid values: 0..(127-FontWidth)
- page_num: the number of the page on which character will be written. Valid values: 0..7
- color: color parameter. Valid values: 0..2
The parameter color determines the color of the character: 0 white, 1 black, and 2 inverts each
dot.
Returns Nothing.
Requires Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routine.
Use the SPI_Glcd_Set_Font to specify the font for display; if no font is specied, then the default
Font_Glcd_System5x7 font supplied with the library will be used.
Example
// Write character ‘C’ on the position 10 inside the page 2:
SPI_Glcd_Write_Char(‘C’, 10, 2, 1);
Notes For x axis and page layout explanation see schematic at the bottom of this page.
Prototype
void SPI_Glcd_Write_Text(char text[], char x_pos, char page_num, char
color);
Description Prints text on Glcd.
Parameters - text: text to be written
- x_pos: text starting position on x-axis.
- page_num: the number of the page on which text will be written. Valid values: 0..7
- color: color parameter. Valid values: 0..2
The parameter color determines the color of the text: 0 white, 1 black, and 2 inverts each dot.
Returns Nothing.

// Write text “Hello world!” on the position 10 inside the page 2:
SPI_Glcd_Write_Text(“Hello world!”, 10, 2, 1);
