PCCARD timings

hello,

Hi I am using a PXA270 board with a PCCARD slot for accomodating WLAN
module.
Can you suggest me the PCCARD timing values for that?

coz we experiencing some disturbance in display when WLAN module is
active.


thanks & regards

The PCMCIA specification allows you to interrogate the card for its timings,
they are somewhere in the Tuples in atttrbute space.

Xscale will cause tearing on large LCD display under heavy PCMCIA load. This
is exacerbated when the tiings for the PCMCIA are too long. So shorten the
timings until the card stops working then back off one step.
If you have 800x600 or larger then you will not elmininate the tearing using
that method alone, although you can make it a lots less intrusive.

To entirely eliminate the LCD artifacts stand 20 metres away from the
display and squint.

Consider using an SDIO WiFi card.
