Hi all,
I am searching for a driver for 6-8 digits of 5x7 LED matrix displays. All I can find seems to be the 4-digit MAX6952/3 chips. Two of these would ofcourse work, but that requires a lot of space and they are not cheap either. I do not really need all the font functionality etc. As long as I can control each LED seperately, I'm OK. Another option would be a chip with only the drive transistors and current sources and do the multiplexing in SW.
Does anybody know of chips that might do the job or manufacturers that carry these things?
Or does anybody know of 30mm 5x7 displays with integrated drivers? All I have found are 5mm and 7mm, 4 or 8 digits (and with this option I need 6 digits). Preferably these displays should be available in red and blue.
TIA,
