I need to display some dynamic Chinese characters to 12864 using Arduino. What to show is transported from my web server. The character is stored as a 16x16 dot matrix, needing 16*16/8=32 byte. And I need to show some sentences, which contains more than 100 Chinese characters.
The problem is that I can't storage all the dot matrix data in Arduino because it has too small memory.
- If I get the dot matrix data from web server, I need to have 100*32B memory, but SPAM with EEPROM have only 3k. So that failed.
- If I save the dot matrix "library" in the Flash memory, I need 3500*32B (There are 3500 Chinese frequent-used characters), but there is only 32K Flash. Saving the "library" means that I should storage the dot matrix data of all the 3500 chars in Flash, then the server only need to send the Unicode of characters, and I can get the matrix of the char.
Any help is appreciated!
