What’s missing? Tell us about it.
I’m checking right now. Jun 29, at 5: The I2S protocol is not as complicated as you think. Most likely I’ll end up sticking to bit. Post 90 of Jun 30, at 4: Post 86 of The only thing with the ISP is that it’s not high-speed capable so it’s limited to 12mbps or so, iirc.
I’m going to see if I can get the IDE bootloader to work–documentation doesn’t seem too clear to me. I’ve gone through most of the scf reference manual, and it seems that the audio outputs both SPDIF and I2S are only capable of bit. This really shouldn’t be too hard to do, and you then have access to most Linux software.
We just need datasehet clean it up and find some alternative chips. The host function is usefull if you want to connect a Portable player to the Dap without the need of a PC. Jul 1, at 3: Uclinux can run on the MC3. All you need to make an interface is three shift registers, a counter and an AND gate. Adapting SPI might also be a possibility, though I think it might take too much processor time.
BTW, I’ve split the audio hardware design section to another thread.
I have done a list of the main components not the resistor, connector, jumper, capacitor Do you already have an account? The ISP would need more work than a simple usb-to-ata bridge, but rockbox supports a player with that chipset so there’s some example code to build on. Jul 13, at 5: The first version of the firmware indeed will probably be something really simple, maybe just a WAV decoder.

You can find a couple of ready made I2S interfaces over at OpenCoresor you can make your own. No, create an account now. All of the ones you mentioned are essentially the same. Post 88 of I might see if freescale will provide sample code for the ide bootloader, since there’s almost no documentation on their site on it other than one or two pages in the datasheet. Datashdet 76 of If we want host capabilities eventually, I don’t mean in the first version of the softwarewe should probably try the ISPaccording to its datasheet, the peripheral capabilities on the chip are the same as the ISP I take a close look to the evaluation board MC3 and the Audio daughter board.
Post 87 of Since this will be programmable by replacing a firmware file on the hard drive or possibly some other meanswe can easily release a more advanced firmware for the DAP dataeheet on without any modification to the hardware. Post 83 of Jun 30, at The ISP is probably your safest bet however.
audiophile diy DAP?
Or if we want to completely drop host capabilities from the first revision of the hardware, we can try looking at cypress’ usb-to-ata bridges. If someone wants to do some hunting, find a distributor that stocks CY7CC in reasonable multiples. I’m still thinking about whether or not we should base the USB on a chip that’s capable of USB host and do the code for host functionality later or if we should just use a plain USB peripheral controller and require a new board for USB host functionality.
Although I’ve already gone somewhat far into the design, I’m still open to any suggestions for another microcontroller. They might not work, as I’ve just glanced at their specs so far. Headphone Reviews and Discussion – Head-Fi. Jul 4, at 1: Jun 29, at 6: I’d rather not have to put a programmable logic device to do that. Let me xatasheet if you need a schematic. Unless someone can find a good source, I think we’re going to end up going for the ISP
