TCON Example
The following is an example of a basic TCON script:
WriteByte (TCON_CTRL_EN, 0x01);// enable TCON output
// vsync start at vcount = 0, end at vcount = 1
WriteWord (TCON_PULSE_0_SET, 0x0000);// pulse 0 set = 0 (12 bit value)
WriteWord (TCON_PULSE_0_RST, 0x1001);// pulse 0 reset = 0x001 (12 bit),
// vertical pulse, comparator 0
// HSync start at hcount = 4, end at hcount = 6
WriteWord (TCON_PULSE_1_SET, 0x0004);// pulse 1 set = 0x004 (12 bit value)
WriteWord (TCON_PULSE_1_RST, 0x0006);// pulse 1 reset = 0x006, horiz pulse
// data enable start at upper left (31H,1V), ending at lower right (1311H, 1025V)
// for a 1280 x 1024 output enable
WriteWord (TCON_WINDOW_0_LEFT, 0x001F);// window 0 left edge comparison
// count = 0x01F (12 bit value)
WriteWord (TCON_WINDOW_0_RIGHT, 0x051F);// right edge count = 0x51F
WriteWord (TCON_WINDOW_0_TOP, 0x0001);// top edge count = 1
WriteWord (TCON_WINDOW_0_BOTTOM, 0x0400);// bottom edge = 0x400, window type
// select pulses and window for oHSync, ovsync, oenab
WriteByte (TCON_X_OHSYNC, 0x03);// HSync on TCON pin 0 is pulse 1
WriteByte (TCON_X_OVSYNC, 0x02);// vsync on TCON pin 0 is pulse 0
WriteByte (TCON_X_OENAB, 0x08);// out enable on pin 0 is window 0
