Hi,
When designing a new solution I've ran into the following challenge:
for a given application I need to find values in a storage table based on date and time. Including the key(date, time)it adds up to 615kB total of data storage that contain values I might need. I could leave out the key and sort it properly so I can calculate the offset in the data where I want to be and that might reduce the data by 50%. This data is foreseen to be refreshed once a year. It originates from a webservice, from which a stream is captured, processed and cleaned into a raw datafile on the pc that can be processed by ie. pc-applications. But I want a picaxe using this data in a standalone configuration. I could save some more data by recalculating date formats (i.e. to julian).
I do have an eeprom burner but it supports only 28Cxxx series maximum so no i2ceeproms. I have limited capabilities in electronics engineering. I have built picaxe applications that used i2c but have no experience in bitbanging in order to get i2c devices to work (tried once, could not get it to work). The whole thing should be running standalone, there are however no power issues.
What type of storage can you suggest me?
