TM1640 based, 16 digit display (dealextreme)

[Panici]

Anyone know about the TM1640 chip? I've ordered one, and i'm going to try and figure it out.

Here is all the reference info I could find:


Schematic: http://ljy99731.13.dns222.net/download/LM1640_sch.pdf
Datasheet: http://ljy99731.13.dns222.net/download/tm1640.pdf


Is it similar to the TM1638, for which an arduino library has already been built?

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.

Google translate is also able to translate that PDF via the "Translate A Document" link at translate.google.com

Wow, 16 digit multiplexed driver chip.
Looks like com, is via I2c going by the pullup resistors.

Can select English here

but the pdf doesn't seem to want to download.

Opens up & just says "Translated version of TM1640", no text or drawing or anything.

Must be on your end. If you open the HTML file all the data is there, and it displays fine on my screen.


It'd probably be easier to just go to translate.google.com and hit the blue link "Type text or a website address or translate a document."
Then just upload the PDF. Worked on multiple computers for me?

Must be me. I cannot get that process to work, just opens a blank screen.

I grab some screenshots of what i've got tomorrow then

I can get the Chinese version of the TM1640 downloaded, translate.google.com won't do the translation.
Need the address information on I2C commands to send it data for each digit.

See attached PDF. Hopefully this works!

Not for me - just 1 blank page. Not getting any warnings or anything.

? Weird!

OK this has to work:
I physically took screenshots of the translated version, I tried to leave some overlap so you don't get lost.

That works! Thanks Panici.

I got my module in the mail today.

If you want to run any tests-by-proxy, i'm game!

I am waiting for my piece anydays now, extremely fun to try something without real instructions (talking about my skills now).

Cheers,
Kari
