Hey guys,

i am a newbie on ST10 Controllers willing to programm ''data paging'' on the ST10. Simplified i can realise this with adding an offset to an address, so i can deal with ''another'' storing area within the 64K space in the small model variant III (48k in 3 DP, and DPP3 mapped to Page 3).

I just want to switch between preset values (i want to store these values in flash, but must not) and configuring parameters that can be modified by the user, stored (of course) in ram.

Is this possible just thru switching der DPP during the runtime? I mean just mapping the DPP to new address?

Thanks a lot.

cheers

Hey Neila,

Thanks for your reply.

I guess, i have just to modify the Operating System running on the ST10 since the DataSize will be smaller than 2KB. So i can use the spare IRAM of a DataPage to store an Image of this data and just switch to the other ''block'' of data.

Regards,
