XOR toggles a bit, whereas &~ switches it off. Those are two different things, I would say.

Correction: it would only replace the block of code serving as a toggle. Replacing (&~) with (^) wouldn't be equivalent.

Speechless: thanks, that would indeed simplify the code a bit.

Yesterday I tried to flash my M6SL with this home made test firmware of mine. It got stuck at "flashing firmware, please wait..". After a while I performed a hard reset, but the player seemed to stay off and not running my code (at least the backlight wasn't toggled). Eventually I was able to get into DFU mode and reflash with an official firmware. Maybe I can do some more experiments today.

if help is need contact me. the code is very simple for me as well and i cant find any errors but i am not strong in programming

ok, today I did some more tests and this time merged the NAND loader with my test firmware (with the merger from DFU manager). The backlight now turns on when I press PLAY and turns off when I release it (which is not what should happen). I couldn't get the piezo to produce any sound. No idea if it's actually running my code. I'll keep you updated.

markun: You should put some key debouncing code here.

wpyh · 05-02-2008

kgb2008: what is "key debouncing code"?

markun · 05-02-2008

wpyh: When pressing the key it might not go from 0 to 1 very cleanly but for example like this 0, 0, 0, 0, 1, 0, 1, 1, 1, 1, 1. To 'debounce' you can for example add a little delay in the code after a key (un)press is detected.

wpyh · 05-02-2008

Um... OK, I get it. Please let us know if you get results with it

wpyh · 05-02-2008

Well, I'm just guessing, but it's possible that PDAT1 signals a key press or release event, and not the key status itself (whether the key is pressed or not).

Really just guessing here.

szarecki · 05-09-2008

hmm

and how is progress of rockbox?

oxyg3n · 05-09-2008

How many people are working on this project ?

I can't wait to see rockbox working on my m6

markun · 05-14-2008

I guess I'm the only one programming and trying to run code right now (right?) Sorry for being a bit unproductive lately. I hope I'll get some more work done soon. Getting a small breakthrough (running some custom code) would be nice for motivation

Next thing I'll try is to replace some code in an official firmware update to get my code running. After that, look how much I can change until it no longer works.

you're right here. we are mostly noobs here. we can just to long tyring work like testing etc. all hope is on you

i'd expect the status

nice2know_u · 05-27-2008

Any news from rockbox project? Does anybody working on it?

OH23 · 05-27-2008

looks like this project is going nowhere...

Err0r · 05-28-2008

I think it's largely due to the fact that we only have one person who can code - markun.

Maybe it's time to start a collection to buy some other Rockbox coders Meizu players too.

vcf · 05-28-2008

dont worry guys. the project hasnt died. just markun is a bit busy last time. in june there will be the rockbox dev's conference DevConEuro2008 < Main < TWiki
there is going to be many work done. as you see meizu has 3(!) devs Meizu M6 - Marcoen Hirschberg, Daniel Stenberg,Frank Gevaerts

Not so. There are a number of individuals here who can code. I think it's largely a matter of someone taking the lead, for others to follow; then we'll see how much skills are available. The skills available are largely shrouded, at present, methinks.

Personally, I have some rusty C and assembly language programming experience, which I haven't had much recent opportunity to exploit. I've not had any experience with embedded programming, and was waiting for markun to give some pointers.

You mean some bribery and corruption? Hahaha.... Well, as you've mentioned that, I'm somewhat partial to a donation of a second Meizu player, myself, if the feeling takes you. As for cash donations, please direct all donations to... Wait a moment... I'lll get back to you. I'm in the process of heading out to buy a large bucket.
