How to access several KBs of data on the PC?

Using Arduino Programming Questions
#1

Hello,

I want my Mega2560 to act as a combination of logic analyzer and system board for a TTL_CPU that I want to test. But I need to load the contents for the system ROM from the PC and I haven't found how I can do that using an INO only. How can I tell the PC sending a lot of data?

Thank you in advance for your help?

Kind regards, Ruud Baltissen

Are you saying that you want to have the Mega act as a ROM for the device-under-test?

What’s wrong with downloading the ROM image as hex (Intel, Motorola . . .whatever format) into RAM on the Mega?

Or compiling it into the Mega’s own image?
