procedure SPI_T6963C_Write_Char(c : byte; x : byte; y : byte;
mode : byte);

Nothing.

Writes a char in the current text panel of Glcd at coordinates (x, y).

Parameters : 

- 

c

: char to be written 

- 

x

: char position on x-axis 

- 

y

: char position on y-axis 

- 

mode

: mode parameter. Valid values: SPI_T6963C_ROM_MODE_OR,  

SPI_T6963C_ROM_MODE_XOR, SPI_T6963C_ROM_MODE_AND and 
SPI_T6963C_ROM_MODE_TEXT

Mode parameter explanation: 

- OR Mode: In the OR-Mode, text and graphics can be displayed and the data 

is logically “OR-ed”. This is the most common way of combining text and 
graphics for example labels on buttons. 

- XOR-Mode: In this mode, the text and graphics data are combined via the log-

ical “exclusive OR”. This can be useful to display text in negative mode, i.e. 
white text on black background. 

- AND-Mode: The text and graphic data shown on display are combined via the 

logical “AND function”. 

- TEXT-Mode: This option is only available when displaying just a text. The Text 

Attribute values are stored in the graphic area of display memory. 

For more details see the T6963C datasheet. 

Toshiba Glcd module needs to be initialized. See SPI_T6963C_Config routine.
