@Jeff_Highsmith Yes, many of the I2C polling examples do not work. There was an update merged into the build to improve I2C speed using DMA, however that seems to have broken traditional ways of reading data from the I2C bus. There is another thread discussing the topic -
I have been told the plan is to release a fix in the next release on or around Oct 15. Till then if you want to get it working you will have to build locally with a version that has the code fix from @satishgn.
