==================================== uLCD-320-PMD2 PmmC Revision History ==================================== ---------------------------------------------------------------------------------------------------- uLCD-320-PMD2-uSD-Serial_rev5.pmmc (5/09/2007) ---------------------------------------------------------------------------------------------------- - Fixed up the intermitent problem with uSD card read. - Added a new command, Video. Syntax: @,V,x,y,width,height,colormode,delay,frames,address Command is similar to the Image command but with the additional delay and frames parameters. - delay: 1 byte interframe delay (in ms) - frames: 2 bytes (msb:lsb) number of total image frames in the movie/animation clip. - Improved the data read-display times from uSD card to screen. 240 x 320 (16bit colour) = 76.8ms to read/display (1.00 micro sec per 16 bit pixel) = 13.0 frames per second 240 x 160 (16bit colour) = 26 frames per second 240 x 320 (8bit colour) = 99.0ms to read/display (1.29 micro sec per 8 bit pixel) = 10.0 frames per second 240 x 160 (8bit colour) = 20 frames per second ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- uLCD-320-PMD2-uSD-Serial_rev6.pmmc (26/10/2007) ---------------------------------------------------------------------------------------------------- - Internal "Auto Baud" detect pin monitoring the Rx line on the PICASO has been causing problems, specially when using the uUSB-CE5. This is now fixed. - Added "PmmC Rev: X" message on the screen for Version Command. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- uLCD-320-PMD2-uSD-Serial_rev7.pmmc (29/10/2007) ---------------------------------------------------------------------------------------------------- - Serial Command "Display Image", bug prevented images greater than 273 lines in height. Now fixed. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- uLCD-320-PMD2-uSD-Serial_rev8.pmmc (2/12/2007) ---------------------------------------------------------------------------------------------------- - Increased the speed of pixels displayed used in most of the graphics primitives (excludes images/movies). - Internal cleanup. ---------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------- uLCD-320-PMD2-uSD-Serial_rev9.pmmc (11/03/2008) ---------------------------------------------------------------------------------------------------- - All issues relating to uSD memory cards larger than 64Mb have now been fixed. ----------------------------------------------------------------------------------------------------
