LPC2214 I2C repeated start problem

Started by "George M. Gallant, Jr." March 27, 2006
I have added a LPC2214 to and existing system that consists of 3
pic18f252's and an i2c compass. The LPC2214 is always the master
and basic communications are working. However, the PIC's are
detecting a STOP condition whenever the LPC issues a repeated
START command. I have a software work around which is to ignore
the STOP status after an expected START command.

The 2214 manual is quite light on I2C details. Any insight would
be appreciated.

The LPC2214 manual is really light on I2C details. Check the LPC2138
manual for some good block diagrams, etc.
