Hi
I am trying to light up a LED dot matrix. I am using a Microchip uC, and extending the outputs with the 74HCT595. What I find though, is that the LEDS are very dim. (7 LEDS are driven by roughly 20mA).
Can someone please recommend how to get the LED's to glow brightly?
I cant source the high current 595 where I am.
Any suggestions would be most welcome.
Regards
