I2C Master Receiver with LPC2294

2005-08-23 by Hogan Chris

I am currently using an LPC2294 in conjunction with a Phytec development
board.  I am able to use the processor to operate as an I2C Master
transmitter, however I have problems when I attempt to operate as Master
receiver.  The slave device that I am writing to requires a one byte
command, in order to describe the data that I want to read.  So, when I
send this command, everything seems to work.  However, when I issue a
stop command and then restart the bus and address the slave device to
read the data I miss the first 1 to 2 bytes of data.  I know that the
slave device is working correctly because I can effectively communicate
to it with an iPort (I2C Master emulator).  I only have problems when I
try to read with the LPC, any thoughts?
