Maximizing Memory for Data Storage

Rabbit
1

I’m using the RCM4300 as a network-connected data logger, and I want to maximize the amount of memory available for data storage. I don’t care if data is located in root or xmem, but I’d like to utilize all available memory. I’ve read in the documentation how to locate functions and data in either the root data space or xmem, but I can’t find anything describing how to adjust the relative size of these areas or how they map to physical memory. (and yes, I have read the chapters on memory management)

Can anyone help? Even partial solutions are welcome.

Dear Bill Hovey,

There is a posible that you can find information in a sample program. If you want to use the SD flash card you can find a sample in:

DCRabbit_10.21\Samples\RCM4300\SD_Flash\SDFLASH_INSPECT.C

There you kan find how many blocks and the size of the blocks. For example my SD card has:

of blocks: 990976

Size of block: 512

I think 1 block is 512 Byte.

I hope that this will help you.
