    Default protocol issues with tls3001

    Hi All
    i am currently trying to design a controller to drive some led tape with tls3001 driver chips but i am struggling with the data sheet
    has anyone got an english translation of the data sheet ? i have run the data sheet through google translate and have coded as far i can go but there is something stopping it from working.
    I did see some mention of a delay prior to the header of the data payload based around the number of chips but couldnt make sense of the translation to do the maths.
    i think the flowchart may have a solution to my problem but i cant read it.
    I have emailed the ic manufacturer to see they can help with the translation
    any suggestions welcome
    many thanks
    Chris

    Give jstjohnz (Jim) a PM - he's got working TLS3001 code for his E680/E681 pixel controller (Propeller based).

    Welcome to DIYC btw!

    Hi
    I am still having issues I contacted Jim but unfortunately he had to sign an NDA so he had his hands tied
    I have tried emailing all he addresses on the Tlsemi website but no one wants to talk to me :-(
    I think it is the issue of the delay to allow baudrtate detection if anyone has any suggestions it would be most welcome or a translated version of the flowchart as I think that may hold the key
    I have put a logic analyser on the line of a working controller But there are some things that don't match up with the data sheet
    many thanks for you time

    This is the flowchart translated. The text at the top of the flow chart in the pdf, is the text at bottom of the flow chart (just didn't move it all).

    You could always try to talk to Ed (j1sys). He didn't sign an NDA from what I'm aware, he just reverse engineered the protocol. mrpackethead might have some info on it as well, not sure if he's limited though.

    big hint people. Theres two vendors of the 3001 IC. Theres the CYT3001, and the TLS3001. One is a copy, one is original. ironically the copy is the one on which you have to sign an NDA. Also noticeably the fault rate in the IC's is significantly higher in one.

    Can you inform us as to which 1 is the original .

    I intend on ordering 32 strings with the 3001 ic.

    Thanks

    I am having some issues with the C code. It seems to send some packet formats that I don't see in the data sheet

    such as this sequence:
    send_head();
    send_flag(0x10);
    send_addr();

    So mrpackethead, are you saying the protocol is (basically) the same between them?
