Thanks for the info wortelsoft!! You are the first person that gives me feedback since I released it.
Thats what ardubus is for, it eliminates coding errors when you are not familiar with the I2C bus or the chip.
Ironically, I first developed it using the IDE terminal and then modified it so it worked with true terminals like putty, but something might have been broken in the process. The IDE terminal isn't a true one, so it is a bit special.
Yesterday I have been tinkering with lighting LEDs methods and the MAX7315 seems to be an interesting chip, but being smd I dont think I could solder it. Did you soldered it by hand?
Thanks for the feedback
