Hi,

I'm using I2C0 in LPC822 microcontroller.
As per the datasheet I2C0-SDA is P0.11, and I2C0-SCL is P0.10.
And in LPC initialization tool , we can choose I2C0-SDA at P0.11 and I2C0-SCL at P0.10. we cant interchange SDA and SCL using pin mappings.

But in periph_i2c_rom_polling.c file, I2C0-SDA at P0.10 and I2C0-SCL at P0.11 .. How is that possible. Please let me know.

/* Connect the I2C_SDA and I2C_SCL signals to port pins(P0.10, P0.11) */
Chip_SWM_EnableFixedPin(SWM_FIXED_I2C0_SDA);
Chip_SWM_EnableFixedPin(SWM_FIXED_I2C0_SCL);

Regards,
Krishnamohan

Hi Krishna,
The datasheet and LPC initialization tool are in good shape.
But the periph_i2c_rom_polling example is broken.
