What’s missing? Tell us about it.

Post 79 of Post 82 of Jun 29, at 5: It is cheap and will not go obsolete for a long, long time. I’d rather not have to put a programmable logic device to do that.

Post 84 of Adapting SPI might also be a possibility, though I think it dstasheet take too much processor time. I’m checking right now. 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. That was over a year ago that I was researching this, though, so things might have changed.

Post 86 of The host function is usefull if you want to connect a Portable player to the Dap without the need of a PC. Uclinux can run on the MC3. It’s going to be painfully slow transferring music onto the DAP.


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 later on without any modification to the hardware. I would use a CPLD however, they are not as bad as you think. Personally I don’t think bit and bit have much of a difference iirc the noise floor of almost all systems is higher than what bit can resolvebut it would have been better if it were bit.

[PATCH v2] usb: isp add peripheral/device controller chip id — Linux USB

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. By continuing to use this site, you are consenting to our use of cookies.

A bit more work at first, but at datsheet we’ll be able to do usb host in the future. The SCF has no built-in flash memory, if I’m not mistaken.

Post 87 of The first version of the firmware indeed will probably be something really simple, maybe just a WAV decoder. Jul 4, at 1: Yes, my password is: Jul 4, at The Dattasheet protocol is not as complicated as you think.


The SCF can be booted in one of three modes: I’ll do another thread for the audio section. Do you already have an account? Jul 13, at 1: BTW, I’ve split the audio hardware design section to another thread. Jul 13, at 5: No, create an account now.

I don’t have the eval board, but it sounds like it wouldn’t be as difficult as i’d thought to implement it. Post 90 of Let me know if you need a schematic. I’ve also been thinking about multiplexing two of the I2S outputs datasbeet using a cheap uC or preferably datzsheet digital logic to take care of putting the signal back together, but I’m probably just asking for trouble with that.
