hi, a friend is trying to make a 'rep counter' has wired up a Picaxe18 totwo 7 segment displays direct. it works when (for example) if you do..... let pins = 9 the display shows 09 but when the output is between 10 and 16 the display shows a blank on the second display.

What is the easist way of making a manually clocked 2 didgit counter?

sorry about poor grammer and spelling, only 6:30 and fireing this off before I have woken and gone to work, many thanks Tom Bayley

USe an external 7 seg driver such as 4026 = they can be cascaded and circuits are common place. Drive it with your picaxe. - just 1 or 2 outputs.

Other 7 seg drivers are available! Interface manual will give some details.

Smells like a BCD issue - once you get past 9, you need some code smarts to send a 0 to the second display, and set the first to 1.
