External EEPROM via I2C (Non-constant address declaration issue)

[Siva]

Hi,

EX_1.rar

Can I define "non-const" variable for writing data via I2C using "APP_TWI_Write" function? Similar for read.

When using External "EEPROM" one should define register address and data to be stored as a dynamic variable rather than const.

When I try to use macros, compiler says "error: initializer element is not constant".

Is it possible to communicate with EEPROM via I2C using "TWI transaction Manager"?

Any advice on this would be great.

Regards

Siva

Please have a look at the TWIS Slave and TWI Master mode drivers Example in the SDK. In this example a EEPROM TWI slave device is emulated and the master reads and writes to the device using the TWI master driver.
