Welcome to the Rockbox Technical Forums!
http://www.atmel.com/dyn/products/view_detail.asp?ref=&FileName=ARM9_Hantro_10_3.html&Family_id=605"AT76C113P" is the only chip I could find so the chip mentioned is up and coming, I think?This is it http://www.hantro.com/index.php?349
Quote:All tools are for Linux and also for M$ Windows. GCC-ARM, text editor and USBprog, they are multi OS - you can see a good example here:http://sunge.awardspace.com/arm-getting-started/arm-getting-started.htmlThats for a at91sam7
Example,we ditched,touchscreen,and touch button and it's fine but if anyone have suggestions for the control is highly welcome.For example a click wheel,similar to the new iriver models could be an example and it won't hurt the design.Any cool feature is accepted,because on our side won't change much 5-10 usd more but could greatly improve sales.The key is to make it unique by merging features not present in current players.
Ok,finally some update.Some good and some bad news.My friend agreed basically because it won't cost anything for them.
That was the good one.The bad one is that in China factories don't work with small numbers,the minimum quanity to build will be around 3000 units,since it involves creating a new case mold and new pcb design.In total 3 factory will be required,one for the case,one for the pcb(by pcb i mean the pcb itself plus the component that require smt machine,excluding soldered components,like battery,jack,etc) and one for assembly.I can see if we can lower the quantity,but will still be a big investment from our side.
So to decide if agree,we should have more concrete data.How many people are willing to join the development?If we have developer known to have experience in this field,we could send the development board to them to speed up the process.Speaking of the development time,6 months seem a bit much for this project,not because it's long per se but because it's open source,and if it catches enough interest any company could just take the design and make it before us.So the shorter the better.
Last thing,as i said before,since it require a big investment it should be more commercial possible.So I would like to evaluate any proposal you guys will make that won't collide with the original purpose.Example,we ditched,touchscreen,and touch button and it's fine but if anyone have suggestions for the control is highly welcome.For example a click wheel,similar to the new iriver models could be an example and it won't hurt the design.Any cool feature is accepted,because on our side won't change much 5-10 usd more but could greatly improve sales.

Another questions: FM/AM Radio?(there is drivers in Rockbox for radio tuners) DAB radio(no Rockbox driver)? - Wireless connection(no Rockbox driver)?
And another: What about patents? like MP3, WMA, ACC, etc? - how it work when Pasen buy from China?
Is the mailing list more followed than forum?I am not familiar with them,i don't like much the mailing list format.
So yes the bad news is for us,and thus for you too As for your second answer,i don't know i will have first to investigate on costs.There is a fair soon in hong kong,i'll send my agent to talk with parts supplier.
I see many list the internal capacity like some hard disk type,if that's the type of player we'll have to call out as will be much more expensive than flash type(and not too small).Also for your information most of the player we build now does use mlc type flash that have slower writing speed than slc,but does have a huge difference in price(for example 4gb mlc is 12 usd the slc is 26 usd).
QuoteAnother questions: FM/AM Radio?(there is drivers in Rockbox for radio tuners) DAB radio(no Rockbox driver)? - Wireless connection(no Rockbox driver)?Yes,from what i read around,most of the users want fm radio even if they won't use it most of the time It would be good if it could support RDS too.Dab radio would rise much the price,and it's not a worldwide standard.Wireless would be awesome,but writing a bluetooth or wi-fi stack from scratch would take ages.Since your os is not a derivate of any other os,there is no stack for it.There is the kleer audio wireless technology,but could be pricey and you are stuck with their earphones or you must also design them.
Huge difference in price? so why do you chose use that? - is really important? is noticeable the different in performance?
I didn't understand... "fair soon"? - other thing, using the components, the MCU that we choose, maybe will higher the cost, but is a "stable", I think that Atmel MCU will be available for long time in market or at least Atmel will provide a continuity MCU and with full datasheet.
INPUTS: * Stereo Line-In for High Quality recording; * Digital-In - preferably via mini-TOSLINK; * Mono integrated Mic for voice recording.
Regarding the hdd question,what do you think of a design like that?It's similar to a design I saw before,except that was carrying a larger battery,not an hdd.The connector could be an 30pin one,like ipod so the player could support ipod accessory,from what i read rockbox does have drivers for ipod interface,right?Of course the player won't have to ship with such driver as that would require a license which i doubt apple will release for another mp3 player
QuoteHuge difference in price? so why do you chose use that? - is really important? is noticeable the different in performance?Actually now we does use the cheaper MLC,which is the standard for all small and medium brands.I don't know about big brands(i think they still use SLC).And yes the performance is much different(1.8mb/s against 3.2 if i remember well,but the situation may have changed with newer flash modules).
QuoteINPUTS: * Stereo Line-In for High Quality recording; * Digital-In - preferably via mini-TOSLINK; * Mono integrated Mic for voice recording.Can the line in be shared with earphones output or it will compromise quality?All these input output can be difficult to place in a small player otherwise.
I have just one suggestion/wish:I'd love if RockboxPlayer don't hiss nor induce some other annoying noise.as for now, I still haven't got in my hands any DAP that wouldn't hiss.
This is a great site for many resources. http://www.busybox.net/products.htmlGive it a look see, may give you some drivers from one of the embedded resource.This is not fun, memory stacks and pointers. Going back to C, after spoiled with C++. I'm going to need more scratch paper. I rather use java based, my html stinks. This is like going back to cobol or fortran from the 70's era, from basics in the 80's. Asm is so long past, the only time I remember using it was when I made my own operating system in school.
Still having problems getting usb to work. I would like to get my hard drive to work. I might have to try this: Windows Embedded CE BSP and CPU Certification Program. The 2 watt stereo amp worked very well, for us that are a little hearing impaired. My module supports earphones, also. The music is very clear and some base to its tone. The 4 gig sd card has plenty music, but I would like to play some divx. For now, its up to someone else to come up with a driver for usb, I'll try to get my free imbedded Windows ce version.
