Increasing 3150 Neuron memory space

Last Updated: August 28, 2009

Question: How can we add functionality that would require more memory than that is available in 3150 Neuron?

Response: The fact is that the Cypress Neuron has a total of 3K of EEPROM memory available; the problem lies in the fact that the Echelon system image and software only support .5K of space. If the extra space requirement is for non-volatile data storage of variables that are under the application's control at all times then it might be possible to directly write to the hidden memory locations using the eeprom_memcpy () command. On the other hand if the additional space is needed for network variables and configuration parameters then these types of variables would have to be handled by the system image and if they exist beyond the .5K border the system image will simply not see them.
