LPC845 Brk - I2C example

[tomato]

Hi all,

I want to try the I2C of the LPC845 BRK following what reported in the user manual

This is the initialization function of the I2C0 in the LPC845brk

And this is the send data function

I tried to launch a program with these two function called but I am doing something wrong.

While debugging the code is stuck here

and the i2c0 registers tell that the i2c is with communication in progress but i tried to see the SCL and SDA lines with the oscilloscopes and I do not see anything passing (always at 3v3). The MSTDAT register has the correct devaddr that I am passing

Can you tell me what I am doing wrongly?

Thanks

Hi,

@VaneB can you help me to use the code bundles and test the I2C?
