    Hi all,

    i am using keil mcbstr750 evaluation board. I have a problem. I create a LCD menu showing various datas which is get from ADC. In addition, i defined some alarms (i.e ''Power High'' ). When the alarm occurs, a LED is turn on. At the same time, i want to write this alarm internal eeprom(16kb). Whwnever i want i read this.For example, In a ''Power High'' alarm condition, in ''Event Log'' menu i have prepeared, i want to see ''Power High:20-09-2009''.

    How can i do that?

    Thank you for your help.

    Best Regards.

    There is no EEPROM inside STR750 or on the Keil board, AFAIK. Either place some EEPROM externally on the I2C bus (and manage to talk to it via I2C) on the soldering area of that board, or check the EEPROM emulation, there exists AN on this topic in some of ARM family.

    You'll need the Flash programming manual for STR7xx MCUs, too.
