Lpc2000

Hi everybody,

I'm quite new to lpc2xxx. I make some test with a keil 2130 eval 
board and now I'm designing my own card with a LPC2292. Does anyboby 
has try to connect a S1D13706 LCD controller from Epson on the 
LPC2292 ? I don't really know how to connect the control pin...

I think : 
ARM    | Epson
----------------
A[16:0]|AB[16:0]
D[15:0]|DB[15:0]
/OE    | /RD
XCLK   | CLKI
/RESET | /RESET
/CS2   | /CS

But for the other (/BS, M/R#, /WE0, /WE1, RD/WR# ??)

Thanks,
Sebastien

You need to connect some of the lines (if needed) to port pins.
AFAIK, the /RESET of the LPC is input only, so if you want to reset the LCD
controller, you should connect its /RESET also to an LPC IO.

And for the others: I would need a description what these do.

Hi,

I've found how to connect most of the control pin but I' ve got a 
problem with 2 :
WE1# (input the byte enable signal for the high byte enable signal)
I think I've to connect it to a GPIO pin

and the other problem , LPC22xx has no WAIT input pin, what cna I do 
with it ?

thanks 
Sebastien

No, you should build this with some logic out of the access lines (A0/A1 
end so on).

Slow down you accesses.

The LPC22xx have Byte Lane Select lines (BLS0 to BLS3) that you can use 
for this. You don't need the WAIT pin, because you can configure the 
External Memory Controller (EMC) with wait states.

I found figure 11 on page 61 and the pin descriptions on page 57 of the 
UM_LPC21XX_LPC22XX_2.pdf explained most of how the external memory 
controller (EMC) works.

Thank you for your reply
I found on the Epson Web site an applicaiton note to connect an intel strong
arm to the  epson controller.
Thyey connect A16:1 of the arm to A16:1 of the epson, adress A0 of epson to
BLS0, WE0/ to WE/ and and WE1 to BLS1.
I think it will work like this.
