SPI_Glcd_Fill
SPI_Glcd_Dot
Prototype
void SPI_Glcd_Fill(char pattern);
Description Fills Glcd memory with byte pattern.
To clear the Glcd screen, use SPI_Glcd_Fill(0).
To ll the screen completely, use SPI_Glcd_Fill(0xFF).
Parameters - pattern: byte to ll Glcd memory with
Returns Nothing.
Requires Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routine.
Example
// Clear screen
SPI_Glcd_Fill(0);
Notes None.
Prototype
void SPI_Glcd_Dot(char x_pos, char y_pos, char color);
Description Draws a dot on Glcd at coordinates (x_pos, y_pos).
Parameters - x_pos: x position. Valid values: 0..127
- y_pos: y position. Valid values: 0..63
- color: color parameter. Valid values: 0..2
The parameter color determines the dot state: 0 clears dot, 1 puts a dot, and 2 inverts dot state.
Returns Nothing.
Requires Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routine.
Example
// Invert the dot in the upper left corner
SPI_Glcd_Dot(0, 0, 2);
Notes For x and y axis layout explanation see schematic at the bottom of this page.
