LCD & Bank Stick

[This N°9]

hello,

I try to connect a bank stick to IIC-port and a

character LCD to J15. When the Bankstick is not

connected, everything runs fine, if the stick

is connected, the LCD won't work anymore,

but the application is running normal.

I did not yet check if Bankstick reads/writes work.

Is it a problem to have a bankstick and character LCD

connected at the same time?

PIN 28 of  the PIC is used for both IIC and LCD port.

What is its function?

thanks, this

The pin is shared but that's OK :)

I wonder if this is related to your other issue....http://www.midibox.org/forum/index.php/topic,12379.0/topicseen.html#msg103103

hmm... I think no. I just disconnected the SRIO boards, the problem

stays. the DOUT-issue is not a malfunction in this way, it's just kind

of confusing..

the test app works as expected, only the MSB/LSB of

the DOUT-registers are swapped. the single registers appear in the

right order.. and with the ribbon cable wiring you have very few

pontential wiring bug sources :-)

I'll check the Bankstick wiring, maybe some solder-bridge or something

(as I already had on a core PCB this mornig..)

some more pics..

me idiot made a shortcut with the mounting screws for the

little bankstick-bord..

but the DOUT-issue still remains.
