[font="arial, helvetica, sans-serif;"]I was wondering if anybody has had success using V4.3 beta on the Netduino Plus 2 with I2C. I struggled today and could not get it working. I ended up using the software approach ([/font]I2C Software Workaround for Plus 2) which seems to be working for me at the moment.

Dear Dave

 

Sometimes sensor company use "I2C-like interface" such as SHT1X from sensirion. I heard that the cause is cost for using standard protocol, I2C philips made. I recommned you first you search it is "I2C-like interface" or not.

 

P.S. Surely I comfirmed I2C bus is working in V4.3 beta. I used DS1307 - (RTC chip).

 

Regards,

Jiwon.

Hi Dave2548, Were you using multiple start bits (as is common when reading registers)? We use I2C frequently with 4.3. If there's a bug there somewhere and you can repro it (logic analyzer capture of some sort, code, etc.) we'd be happy to dig in. Thank you, Chris
