Re: Hooking up to e-ink display?

This is the only e-ink display I could find for sale, but it's interface is similar to some old-school STN technology, I have no clue if it can be hooked up to the PI. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=221047082891&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en ope...

Re: Clarification for screen idea.

You want to power the LCD from a battery, and the rest from a "power supply", or just everything off a battery? You will have: - a board for the screen, that usually is powered by a 12V supply. This board powers the display and all it's needs. - the PI, needs 5V - the usb hub, depending on...

Re: Yep - another cheap touchscreen question..

It seems you need a lot of IO pins for this display, as just the data bus is 16bit.
I would try the MCP23S17 from microchip, an SPI port expander, you can connect several (up to 8) on the SPI bus, then modify the software to use the SPI bus.

Re: I2S: Anyone got it running?

Hi Ears, I have the same numbers for FLEN & FSLEN. For CH1POS and CH2POS, I would go for 0 and 16, that is CH1 starts with the first clock in the frame, and CH2 with the 17th. It's not the bit number, but chronological order. "Channel 1 Position This sets the bit clock at which the first bi...

@error404: the DAC master clock is not actually part of the official I2S specifications. I2S is three wires. Source here. You're talking about the system clock required by some dacs to operate, that is not supposed to be supplied by the PI, nor is it part of the I2S bus. For example "The system...

Re: Useful Screen, or Useless Garbage? RePicyling?

Most portable DVD players have an "AV in" feature. Check to see if you have it, usually it's a 3.5mm stereo jack where you can plug in your composite video signal (RPi RCA connector). I've got a Panasonic LV60 which works in this setup, see your user manual, if you still have it. Edit: as ...

Re: I2S: Anyone got it running?

Thank you, Gert!
This means I have to read the registers, mask the bits I don't want to change then write the updated values.
I hope I'll learn how to actually do this soon, I haven't wrote a line of C code since... I can't remember.

Re: I2S: Anyone got it running?

What I understand from the code: *(clk+0x26) and *(clk+0x27) are the two registers given by Gert, 0x7E101098 and 0x7E10109C. The value " 0x5A000000 | 3<<12 | 1<<9 " translates to 01011010.00000000.00110010.00000000 in binary. So if we extract bits 23-12 we get the integer part: 00000000.00...

I think the OP wants a splash screen, not a logo, so splashy should be just fine.
