I have updated the I2C Interface Example with WICED SDK-3.x platform files for different SDK releases on BCM43362WDC4 platform.
There are no changes are needed on the BCM43341WCD1 platform files.
The sample i2c_led snip application implements basic error checking handling.
The I2C APIs, used by the i2c_led snip application, are already being used on other applications such as interface to MFI Auth chip, NFC interface on BCM43341WCD, and others. The sample i2c_led snip application and other applications using I2C APIs are using DMA and have been tested. If you stumble on any issue please let us know.
Do you have any specific sensor in mind that I can interface it and share?
