I am using the LPC1343 and the I2C driver came from nxp code bundle. Before when I'm using the Level 0 optimization, everything works fine. But when I started using the Level 1, the I2C state is always busy. Can you please tell me what causes this problem???Thank You</SPAN></BODY></HTML> Thu, 16 Jun 2016 02:29:33 GMT https://community.nxp.com/t5/LPCXpresso-IDE/I2C-problem/m-p/577674#M23312 lpcware 2016-06-16T02:29:33Z Re: I2C problem https://community.nxp.com/t5/LPCXpresso-IDE/I2C-problem/m-p/577675#M23313 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by serge on Thu Jun 14 00:11:19 MST 2012</STRONG><BR /><SPAN>I am afraid that at the moment i am not able to test anything.
