AMD_UV-EPROM_Read_Mode.ino
csharp
This part of the code is simple represantation of the reading process and how to read data from the memory-card. Same logic holds here, the actual code can be shortened up to 1/4 of the current size..and /or used with Arduino EPROM library.

I made the most simple way to write data to EPROM for easy understanding how everything works, but one might easily shorten this code up to 1/3 of the current size ^^). This code can be used to write data to all of the EPROMs addresses. Additionaly Arduino EPROM library might come in handy here.

This part of the code is simple represantation of the reading process and how to read data from the memory-card. Same logic holds here, the actual code can be shortened up to 1/4 of the current size..and /or used with Arduino EPROM library.

Memory-Card schematic for general overview
Use the schematics to understand the basics, you have to read the datasheet to find the correct address lines and data line to connect them correctly. The data-lines and address lines are shared for all EPROMs only Control line GPIO needs dedicated pins on µCU.
