Hello

Have anyone tried to use external code memory (flash) with mega128?
Is it working well?

Thanks.

Jacob

No standard AVRs can use external code memory--only internal flash memory can hold instructions due to the architecture.

This has been discussed on the Forum many times before--search out the applicable threads.

Alternatives include a tokenized language with the program tokens fetched from external data storage and interpreted by a kernel in the flash memory of the AVR.
