That said I need to clarify that this assembler version is a modified
|
|
version, because both MCUs are different. atmega328p has less pins, and
|
|
it is slower than Dmitry's project, because Arduino has just a 16Mhz clock.
|
|
Also, the Dmitry version does not work with atmega328 without several changes.
|
|
|
|
In order to have a proper working code I needed to read the datasheets.
|
|
I studied the KM41C4000D, KM41V4000D CMOS DRAM datasheet and other sources like
