i2c lpc2368

There are two sda1 and scl1 on the lpc2368?

And does anyone know the difference in pinsel between the two?

  • Thanks for the reply.

    Its basically page 115-158 in the lpc23XX usermanual.The board I have is the mcb2300 version 3.I assumed sda1 and scl1 were pin 85 and 83 as this is what the board schematic showed.However at the end of the schematic it has another lpc diagram,that of the lpc2368FBD100 which i believe is the actual one on my board and this diagram shows sda1 and scl1 as pin 46 and pin 47.It does seem in many mcb schematics that there are infact multiple sda 1 and scl 1 's.

    One more point I am confused on is in the actual code.When using pinsel,for example

    pinsel0=0x0000000F //How do you know what value to give it?

    Many Thanks for any advice
