Has someone already succesfully used the ni i2C library to read/write an eeprom with ni pxi 6551 on labview?

[Johanna D.]

Hi,

I'm trying to read/write an eeprom with an i2c protocol and ni pxi 6551 module.

At first, I tried to simply read the eeprom, because i know i am expecting 11111111 as a response, but it did not work.

So I tried something easier, and I succesfully wrote a pcf8574ap.

But i can't read it.

Seems like I am not able to "hear" the answer; when the sda line should be filled with an 8bit information, it remains at Z-state.

And because I am using the i2c library, i think there might be a problem with this library, or i am doing something wrong.

Hoping someone has an answer.

Johanna

I think the best place to ask your question in this thread

I2C Digital Waveform (IDW)

I already looked at all NI information... So this website is no news for me, muks...

I posted my request on the thread you told me to, Phillip, hope it will get an answer.

Thank you both,

Johanna
