LabVIEW for ARM V8.6

The address 0 EEPROM page datas are why did not modify?

Try this snippet (or redraw your diagram in 8.6)

Thank you for answering!
I wrote a program in accordance with the picture, but running, reading back the data is 0xFF, do not know AT24C02 chip is broken?  tomorrow to buy chips, then a response ... ...

EEPROM chip replacement, and test did not succeed, the result value is 255?

Have not run well in the I2C example? Today connected to the clock chip DS1307, during the debugging, the data to write and read  is also wrong. . .

[mcusir]

Here is my running for the AT24C02 chip program results, in the front panel the Read Data does not display the results? Always gray state.

I observed with the oscilloscope on the signal waveform SCL and SDA. This two signal lines up-pulled 10K resistor. No run-time waveform created?

Hi, read and write on the AT24C02 chip finally succeeded! Chip address only low 7bits effective. Do not add read and write bits.
