Anyone know about the TM1640 chip? I've ordered one, and i'm going to try and figure it out. http://www.dealextreme.com/p/jy-mcu-16x-digital-tube-yellow-led-module-104311
Here is all the reference info I could find:
Is it similar to the TM1638, for which an arduino library has already been built? http://code.google.com/p/tm1638-library/
I've contacted the author of the arduino TM1638 library, and he's also got one of these units on order, to try and figure out.
