View data memory

The arduino has three memories, being data memory, EEPROM memory and code memory. The division of these memories in different locations is called a harvard architecture. This is different from the von neumann architecture used on the PC.

The view of the data memory allows you to see what is inside the memory. This is a simple dump. If you want this memory to correspond to real variables you need to use an external debugger, like insight.

The view looks like:

Sometimes we need to change a byte inside the memory. Then it is a good idea to know exactly what byte that is. If we know what address we want to change we can simple fill out the address and the value to change to.

In the Change value field press enterand the byte will be written in the memory.
