I got those LCDs "aitendo" web shop in Japan.http://www.aitendo.co.jp/
I got CASIO "CMV54NT04P"http://www.aitendo.co.jp/product/1378http://www.google.com/search?hl=ja&biw=860&bih=576&rlz=1R2TRDJ_jaJP360&q=%22CMV54NT04P%22+price&aq=f&aqi=&aql=&oq=&gs_rfai=
In Japan, it is popular pinball game. And The LCDs had been used as display.They have been around secondhand. So, they are cheap.
SHARP LCD seems to be senstive to the vertical sync sgnal.
So, I like CASIO LCD but CASIO LCD seems to be sold out.
Actually the number of horzontal lines are more than 255 ( non-interlaced method)...
CASIO LCD is OK - 1byte counter for horizontal line count.
SHARP LCD needs 2byte counter.
ATmega338P is 8bit microcontroller......so 2byte operation takes time.
They are Analog RGB. And "Bad Apple" movie is 60 frames per second, 144 * 108 pixel.
(144*108)pixel/8bit = 1944byte <- need for V-RAM
but ATmega 328P has only 2kbyte RAM.
So, the screen is divded in half in the process.
144*108 It seems to be a little unreasonable.
The process SD card reading is overtaken by display process.
It becomeds the noise of the screen.
So, I am organizing the program to lower the resolution.
I will up the skech about next week end.
Why I orderd PCB, you'll understand to see this movie.
I changed ending.http://nabermc.blog137.fc2.com/blog-entry-19.html
