Thanks to hippys discovery that tickling an 18x can make the outputs inputs http://www.picaxeforum.co.uk/showthread.php?t=5827&highlight=18x+bi-directional it's is conceivable to control 56 LED's (charlieplex).
I only want to control about 20 so this works for me if I want to have individual LED's on. But Im trying to make a cylon/kitt chaser and want the fade effect on the trailing LED's. At the moment I have sub routines for each led for example
Anyhue got it working perfect for six LED's bar the fading bit, anyone have any suggestions how/if this fading could be achieved?
Cheers
