Hi nickagian,
first of all sorry for confusion posting and also thank you very much for replying. i am using evb90129 evalution board,in that board mlx90129 ic and one light sensor and external temp sensor and trimmer sensor is there and mlx90129 having internal temp sensor also.mlx 90129 act as a standard lone data logger i think you also that one. it can communicate two ways one is rfid reader and another way is spi communication. i am using spi communication to read sensor values, for that i am using ATMEGA168 microcontoller, i am sending commands through hyperteminal communication.(i mean i connected my pc to microcontroller by using usb port,in my pc i am using hyperteminal to send spi commands), and i connected microcontroler to mlx90129 by using CON1_SPI you can see in data sheet also. mlx acts as a standerd alone datalogger so i set the configuration and i read the sensed values from mlx. that evb 90129 having external spi eeprom (128kB) if we want we can use that external memory in datalogging mode. i am reading values form mlx but when i am using external memory as my destination adress then i can read values so i need help which commands is used to read external memory.if you see the data sheet you can understand easily.i am sending my datasheets also.
best regards,
