LPC 55S28 evk cmsis driver developement i2c

[vi77]

Hi,

    I am new to lpc , working on lpc55s28 evaluation board, need to develop i2c drivers for it using cmsis in keil. I do not want to use the fsl drivers available , i went through the example projects provided using cmsis i2c it  uses the fsl i2c driver .However my aim is not to use the fsl drivers and develop a generic driver i2c  but i am not able to proceed ,can anybody suggest any documentation to start with or examples ,guide to write a i2c driver. Thanks

Hi,

 General sequence for design any peripheral without FSL file in nxp,

•   Enable the peripheral and pot clock
•   Enable port pin and update alternative function as I2C.
•  All other peripheral configuration and control register update code available in user manual page 561 &562
