Hi Martin

Thanks for response.

I found that working, the reason was extra pull-up on p.26 and p.27.

Hi Dhillon,

I do not know how to use the "Arduino Example code", but it is possible to choose which GPIOs the SCL and SDA signals should be from. (This is done in the application.)

P0.27 and P0.26 should not be a problem to use.

I recommend you to check out the TWI sensor example in our SDK, it works "out-of-the-box" and uses pins P0.27 and P0.26 as default. (you can change the definition of these in the "pca10040.h" file)

I also recommend you to check out "SEGGER Embedded studio" (we provide free licence). (Getting Started Guide)
