hi
i need your opinion for designing an 5x7 or 5x8 or 8x8 dot matrix led sign
i'am going to use a PIC as a MCU and it will have a tempreture display
+ time/date and a messege's with an extra set of font.
what will be the eazy way to iterface the dot matrix to the PIC for simple
addressing and power handling with the consederation of useing 2 ROWs
please give advice on chips to use i'am thinking of the 74hc595 on the columns and ULN2003 or 2803 on the rows.
thanks
