RE: programming i2c device with TINIs400 (which address for SDA/SCL)

I've just got my I2C running on a similar HW configuration (TINITs400 with
5V I2C bus). This is the code I used (straight from the demo app )

        port = new I2CPort();
        port.setClockDelay((byte)2);

Works great. I'm controlling PCF8574 8-bit I/O expanders.

Unfortunately with the limited information provided it's impossible to tell
if you have a hardware or software problem. Can you post the pertinent code
fragments?

Subject: [TINI]programming i2c device with TINIs400 (which adress for
SDA/SCL)

Hi,

I have some trouble with I2C ... My tini board is a TINIm400 on a
TINIs400 socket (out of the box)

I have selected  5V pull ups for the I2C bus via the J23-25 solder
jumpers. I2C slave is a SAA1064 (4 x 7digit led)


I don't understand how to instanciate a com.dalsemi.system.I2CPort()
I try to do as in the example i2cTest.java but it does not work.(is void
parm. constructor only for 80C390 ?? javadoc is not very clear...)
I try several delays...

My test application display nothing (the first read over I2C fails).
Unfortunatly, I do not have a scope ...

If I would use the 2nd constructor (with io adress) which one use ?


btw, where can I find memory map and device adress map of the tinis/m400  ?


thanks
RP
