Rockbox Project (M6)

markun

I think it's wonderful too of course I'll try to get some rockbox/meizu stuff done this weekend.

btw, the shipping of my meizu got delayed and they told me it will probably be impossible to get an M6SP so instead it would be the SL. I don't really mind. It would be nice though to have several devs with different models.

PS. Someone called for me on IRC yesterday night when I wasn't at home. Was it you by any chance, kgb2008?

kgb2008: How did you find out that the LCD driver IC are/might be the S6D0129/S6D0139?

roelandb

i'm sorry to hear you will not be getting a sp-model, since most of us have that version. Will you still be able to develop rockbox for both versions??

vcf

yes the majority of us have sp. but if markun will bye sl it dosent turn the things dramaticlly, does it? as i understand as rockbox supports and audio chip which is in sl and which is in sp one module of rockbox will work and on sp and on tp and on sl! isnt is so?

markun

I don't think that will be a big problem. Most of the code will be shared between the two versions of the M6.

roelandb

oh ok, i really hope so, becouse it would be a shame if rockbox was only available for the SL series.

markun: The S6D0129 is the most popular single chip QVGA LCD driver of Samsung TFT panel in these years, in the case of Toshiba, it will be JBT6K71.

Just look for the pattern of bit-bangled SPI subrountines, locate the one would be called at the moment of LCD start-up, we can get the initializing command series, and know that the gamma setting register is from R30 to R39 and the display control register is at R07. it's quite difference to the other SEC LCD drivers, but match with the S6D0129/139.

The Toshiba screen in the Giabeat uses a NEC uPD161704 I believe, so maybe it could be that one as well. Would you be able to tell from looking at the M6T firmware?

kgb2008

Markun: I can't tell you which LCD driver chip is employed inside M6T, 'cause i don't have any spec or reference code about toshiba's QVGA LCM. The register initial code of the LCD driver on M6SP/SL/TP is something like below, you may check if it's familiar.

I didn't know that the M3 was so similar to the M6. It has some components of the SP and some of the SL. I read that it has the same screen as the nano 2nd gen, but I couldn't find out which one that is. I think I've found the LCD init code. Do you recognize which driver it is?

EDIT: I see now that it has some similarities with the S6D0129/39...
EDIT: I looked at the datasheets of the SD6D0110 and 114, but both have less than 0x46 registers.

S6D0123, I guess.
