Hi,

 

What options are available to store data besides the SD card? Is it possible to hook up an extra eeprom to the ND2+ to access and write to it's memory?

 

The data will most likely be hour meters or something simple, so in other words I don't expect to use it as a buffer stream or something that i write to constantly.

 

Any (tried and tested) ideas would be great! Thanks

of course it should be straightforward to connect a serial eeprom to either the spi or i2c bus, or bitbang if you have to and you have some time.

While I haven't done it on the np2, I certainly have on other processors, and I have done other i2c things on np2, so I'm confident it will work fine.

Now I'm curious, I have a device laying around somewhere, maybe I'll hook it up and try, but I'm sure you can get it going yourself, too.

I've tested AT24C16(I2C) and W25X16(SPI) with NP2+,all works fine.
