Saves 100+ bytes (50 of it in iram), saves a bit of power Internal LCD clock decreased but with added efficiency of drawing routines loses only around 2 Hz on the scanrate (~75Hz) while fps is slightly increased Column offsets are now calculated outside the loops saving a few instructions Passing a LCD_NOP command after lcd_update turns off Data/Cmd# gpio saving a bit more power Added a function lcd_write_cmd_triple() that allows 3 commands to be sent at once when enabled with LCD_USE_FIFO_FOR_COMMANDS it sends them back to back without checking FIFO status in between or sending to thhe D/C# Gpio. Makes an assumption about the FIFO being large enough to accept 3 commands after being emptied which should be the case on the clipv1, clipv2, clipplus. I have only enabled it for the clip plus as thats the only device I have to test it on. On clip+ the SSP clock is now turned off when screen is off Change-Id: Ib5fd24697bfe4ac8b8ee017361e789e4a7910d21 |
