I2C on PIC32

[edlaurence]

Hi again Lubin,

Looks like my last thread got hijacked so here it is again....

I'm having some problems building a model to communicate between a PIC32 (32MX360F256L) and a Bosch accelerometer (BMA180) using an I2C bus for a heli autopilot application. Looking through the posts on the forum I think this problem was found by another user earlier this year and seems to fall over at the following point during the build..

I saw that you intended to take a look at the I2C blockset for PIC32F and was wondering if you had managed to make any progress on this issue? If you need any info from me please let me know.

Many thanks,

Hi Lubin,
I've got the same problem.

All,
This belongs in the BUG REPORTS forum.
I will re-post there.
