Full Version: FM Radio Tuner for Zaurus?
OESF Forums > General Forums > General Support and Discussion > Accessories
prensing
I have been thinking about buying a Zaurus as a replacement for my older Visor, but also as an MP-3 player. However, one thing I would lose by not getting a dedicated MP3 unit is the FM tuner. Note that I am not talking about an FM transmitter; I want tune in broadcast radio stations.

I have found a few models of FM tuner CF cards, but I have not found any reference to Zaurus drivers. The common one I found is the Ambicom card (Ambicom FM-CF), but there are a few others.

Does anyone know whether someone has attempted to get one of these working on a Zaurus?

Thanks in advance.

I have this device and planning to write drivers for it some day... Have no idea when smile.gif

Great. If that's the case, I'm thinking I should pick one up while they're still available. I found them here. Does anybody have experience with these guys (techforless)? Especially shipping to Canada. thks

I bought Casio E-125 from them at a very good price years ago. No problems. It was US shipping though.

Definitely would like drivers for this! I bought mine two years ago only to learn it would not work in the Z.

Well, if you guys want a driver (and I want one too) then why don't we sponsor it?

Maslovsky, are you still interested in writing it?
If so -- do you have a rough estimate how long it will take to develop it, probably along with some GUI?

I would like to sponsor it via Paypal, if these minimal conditions hold:
1. Released under GPL-compatible license (of course).
2. Works with both Cacko and OZ on the 5x00 models (yes, both 5500 and 5600).

Any other takers or opinions?

I'm interested. I would be willing to help facilitate this via the OESF. This is one of the reasons why we founded the OESF, but as we're still getting things off the ground, larger development efforts sponsored by the OESF will have to hold off.

That said, the OESF can match all donations 2 to 1, and possibly more depending on the total bounty needed.

Does that help?
maslovsky
Guys, I will have a look at what it will take me to write a driver for the card (I never wrote a linux driver yet) and will let you know some time next week.
offroadgeek
I just got three of these cards, so if there's a developer out there that wants to hack together a driver for he Z I'd be happy to send you a card.

Much appreciated.

I'll donate $50.00 (yes, fifty bucks) through Paypal toward the development of a driver.
I am willing to be a beta tester for a 3.10 Sharp-based ROM on the 5500 (I am using Cacko/Crow) and for OZ 3.5.3 on the 5600.

Additionally, I may debug and/or help with the development of a Java-based GUI/frontend.
I'll setup a CVS or SVN repository for the source control and will host a feed site/mirror.

Having in mind offroadgeek's and OESF pledged support I doubt there were _ever_ better conditions for development of a small-scale OSS driver.


Takers?

I'd consider taking a crack at writing a driver for one. It looks like all the audio is handled through a headphone jack on the card itself (likely to simplify the interface and use the headphone cord as an antenna), so the "driver" for the card is purely for tuning and volume.

What does the card get recognized as when it's inserted?
chyang
I am also attempting writing a driver for it. I have bought one card from local dealer, the price seems to be acceptable so I just bought it. Don't know the difference between mine ProLink FM201 and the Ambicom one, they look identical, so may use the same chip or pcb. It will make us a little happier.
In fact, a little surfing, I got a better price from buy.com: $31.25
http://www.buy.com/retail/product.asp?sku=...hdwt=22114&sp=1
Mine from local dealer was even lower than this price, which made me happy. smile.gif

What astonished myself is the driver part, mine comes with a floppy disk, thanks to my desktop, it can still handle it. smile.gif Search from web returns the identical driver. I'm now turning to Ambicom's driver for more information.

I would like to discuss with you guys on the right approach for hacking a working driver for CF devices with only CE driver.
Both CE driver and Linux driver may rely on the underline PCMCIA controller, which encapulates some PCMCIA support, so we may only need to hack the layer above this.
The CE driver itself exports several routines, which seems to be the
INIT/READ/WRITE/SEEK driver part, we can rely on these routines for more information.
On linux part, it seems that we may program in the V4L way. More work needs to be done for me. sad.gif
chyang
New Driver pack:
http://www.ambicom.com/support/driverdownload/FM-CF.zip

It is quite huge compared with my driver from the floppy disk.
chyang
Oops, It seems that my hardware is different from the Ambicom's one, in spite of they do come from the same designer: ProLink, but it seems that mine is FM201, while the Ambicom's is FM203.
Any WinXP usage report? Can you guys use Ambicom's card function correctly? Even after hack the inf part, which made the driver work with my FM201, it seems that it doesn't function correctly. sad.gif
It seems that I need to buy a new one in US. sad.gif

I just donated an initial installment of $25 to your account to get started. I rely on you to match the donation, coordinate the effort and keep us informed.

The other $25 I will donate as soon as I test the driver+GUI on the hardware in my sig.

Well, I am happy things might be easier than expected.
I do hope, however, that any option to use the speaker of the 5600 will be pursued -- I am ready to be tester for this along with anything else.

I would expect the GUI to have (some of) these controls:
* a Power-On/Off button
* a Mute button
* Automatic/Manual Tuning start-button
* a Volume button
* a couple of Presets buttons and an option to store presets
* an option to set the frequency (range) for the US/Europe/Japan
A sliding ruler to visualize the tuning and allow for manual adjustment might be nice, but in no way mandatory. A digital-clock-type frequency counter might be enough.

I don't know about the differences with the Prolink Card, and I do not have XP.
However under Win2K with the drivers on the enclosed CD the card works well (only the sensitivity is a bit low and the GUI is quite ugly.)

I bought mine new and unopened on EBay for about $25. Unfortunately, currently there are no offerings. I'd suggest you ask offroadgeek to send you one of his as he kindly offered.

Hmm, let's get started then!

I have got the card from offroadgeek when I was visiting USA.

Here is an update:

1.Referenced the Radio TrackII driver in Linux driver for some information on FM card working model
2.Read documents on V4L for FM card control
3.Reference wireless pcmcia driver for PCMCIA service control and programming
4.Dig the internet for available information on the card
5.Disassemble the PPC and XP version drivers for more information

A little finding:
PPC's PCMCIA interface seems to be similiar to Linux's.
Card configuration may be available in PCMCIA Card Information Structure part. I will try to find out whether it is feasible or not.

Challenges
Reverse engineering the card control part
chyang
Updated:

Create a skeleton which can work with the CF driver to recognize the card, while no functional support.

Todo:
Know the working flow of the CE driver based on binary and transplant it to Linux

I've been lurking for a while on this thread. Am quite interested in this idea. Is the interface to the card purely for control, or is it possible to capture audio from it?

great news and well done on progress!
chyang
Update:

Today, verified the chip used in the CompactFlash card, which was refused by AmbiCom's technical support to provide. The CF card itself is easy to unpack, I will attach the photo taken when it was naked. smile.gif

The chip used is Philips TEA5767, seems to be widely used. I will also attach the datasheet for it.

CE's driver part seems to be endless, I was so hard at reading the code, but it seems without datasheet, it's too difficult to do reverse-engineering.

A little search with Linux showed that the chip with I2C was contributed by developers and provided as patch to 2.6.12, so life seems to be a little better. smile.gif

Dawning ahead! Keep marching! smile.gif

Hi - read the post about the FM card for the zaurus with interest. Have you made any progress with the development of the linux driver for the Ambicom FM Radio tuner Card?

How long will it be do you think, before you have something working?
sds
I still have the second $25 up for the driver.

Chyang, I think you made some very good progress.
But are you still working on this? I see you were busy lately with Bochs (which is another very interesting and important project -- also for me).

If it is too hard, or you do not have the time -- no problem! -- please just let us know.
chyang
Very sorry about late response. I was absorbed by bochs/C3k some time ago and will spent time in this from now on. Thanks.

An update:
Seeking for help from TEA5767 author on the driver part.
And also I'm trying to figure out how to write the I2C driver on top of PCMCIA.
chyang
Update, tried the I2C skeleton driver, and it seems to not working.
So I took the photo again to check what the chips are, here is the chips on the PCB.
It seems that the CF card is in 3-wired mode.

I guess many people like me are interested in the news/talk and other features of FM radio, hence the necessity of a FM driver.

[Edit: Edited for more polite expression of the same idea]
speculatrix
I wrote some instructions for Normsoft (pocket tunes on the Palm) on how to set up Winamp as a shoutcast server, so you could stream from line in on your PC, and thus listen to it on the Palm over a bluetooth connection:
http://www.mansfield.co.uk/normsoft/windows-streaming.html

using kino/mplayer, you could also listen to the stream using a wifi or bluetooth connection - in theory it would be better than using the Palm because the Z can do PAND rather than PPP over RFCOMM.
