I'm constructing a 5-digit button counter that can count up to 99,999. I'll be using 5 charlieplexed 7-segment displays, without drivers or transistors. Attached is a sample of the connection of the 7-segment displays. Is it possible to connect five 7-segment displays without using transistors? I also need help in the code to control all 5 digits. I've seen a lot of sample codes for charlieplexed displays, but it doesn't work with my circuit. How do I control each of the displays? I've only managed to code one 7-segment display. Please help. Thanks.
