Re:running LED 5X7 matrix display |

Hi,
I am implementing the 5X7 LED matrix display of 20 LED matrices. I need to implement in Tamil font. But i didnt have experience in designing with LED matrix.
Now i studied about the LED matrices and driver ICs in the net. I collected the knowledge about some of the ICs. Finally i decided to use MAX6953.
In that IC we can store 24 user definable characters in the RAM. If power power goes off then the content ( user definable characters) will be erased.
I have a doubt in that, can i design the matrices for tamil font?
Is there any other possibilities present?
Can i have a circuit diagram for 4 5X7 LED matrix?
Thanks in advance,
Regards,

First of all and sincerely speaking, I do not know anything regarding Tamil font, searching in the web I found this:
http://www.wazu.jp/gallery/Fonts_Tamil.html
I guess that those symbols/char canĀ“t be represented using a 5x7 Leds array. I suspect that you will need
a higher resolution array, like 8x8.

Here you have a 4 8x8 Led matrix circuit:

It use another compiler but it is easily portable to CCS.

Hi,
Thanks for your reply. Sorry I have added Tamil fonts. Its my final target. First i have to familiar with English fonts. _________________ embedding innovation in engineers |

hi,
Now i am trying to display the English character uaing PIC 16F877a controller. I am using the driver max6953 in the code library section.
1) I have a doubt that how we can shift the data to the left side or right side in the display?
Thanks in advance _________________ embedding innovation in engineers |
