Hi.

i willing to make i2c working in fx2lp 56pin.

but i have somequestions.

1) Are there any configuration setting(such as DSCR.A51) for I2C work in HW?

2) may i just only use following functions for i2c work ? (declared in EZUSE.LIB)?

EZUSB_InitI2C(); // Initialize I2C Bus

EZUSB_ReadI2C(I2C_Addr, length, buf);

EZUSB_WriteI2C(I2C_Addr, i, ee_str);

Hi,

You don't have to do any other settings.

You can directly use the functions

bit I2CWrite(BYTE i2cAddr, WORD addr, BYTE write_dat) and

bit I2CRead(BYTE i2cAddr, WORD addr, BYTE *read_dat) which are present in the i2c_hw.c file.

If you need any technical help from Cypress related to I2C or any other block for that matter, please create a tech support case so that one of our engineer will help you in developing firmware or the application on the PC side. Also in debugging the firmware.

Thanks,

sai krishna.
