[General] SPI EEPROM compiler and programm

[Syafiq87]

Hi,

:bang:

We are making product that which need to read the default value from EEPROM every time the MCU are wake up.
The default value will change according to product specification.

We are planning to use SPI EEPROM for model of 25AA1024.

Do have any recommendation that we can load in the value to the EEPROM independently and do have program (Compiler) to be set in the PC and able to download the value to the EEPROM?

Thanks

Even if the compiler you are currently using offered such a feature, it would still require some method of interfacing with the SPI interface directly to load the correct values into the Serial EEPROM.

There are several devices with a USB interface which provide a means to directly interface with a SPI device such as the Serial EEPROM you've chosen.

These devices would allow you read and write values into the Serial EEPROM and typically feature flying leads which can be connected the SPI device via microclips, header strip, etc.

The TotalPhase Aardvark I2C/SPI Host Adapter is one option.

Another lower cost Open Source option would be the Bus Pirate available from several distributors:

Sparkfun Bus Pirate

Seeed Studio Bus Pirate v3.6

The TotalPhase Aardvark comes with an excellent GUI software interface which is fully scriptable and their technical support is excellent as well.

The Bus Pirate is configured via a embedded console interface and may have several contributed software packages, including a scriptable feature as well.

Most compiler and IDE platforms offer the ability to execute external scripts or applications which could be utilized to perform the proper configuration of the Serial EEPROM via one of the above interfaces.

Of course the other alternative is to order the Serial EEPROMs already properly configured/programmed by the vendor. Most vendors of such devices do offer such services for a nominal fee.

If you are using PicKit2, you can make the adapter for our EEPROM and program it with PK2.
Check the PK2 documentation
