Looking for tip how to interface 7 segment LED display with Teensy 3.6.
Project are a rebuild with existing user interface with several common anode 7 segment LED displays and a 4x4 LED matrix which need both source and sinking.
Initially I hoped to find x4AHCT chips to do this, but those I’ve encountered don’t have the capability to drive LED’s much better than the MK66.
Old 5V LED driver circuits suggest current draw needed for LED's used on the panel are around 14mA.
