multiple i2c master in MQX

[antonychen2008]

Hello support:

I am tring to implement an application on dealing with multiple i2c master in MQX,

For example,  when I open one device handle

file_handle = fopen ("i2c1:", NLL);

Then the other device tries to open the same port successfully.

Does MQX driver supports it ?

Hi Andy:

Current MQX I2C driver was not developed/tested for i2c multi master environment. That needs a completely re-design the mqx i2c driver to arbitrate multiple masters that make use of the same bus.
