Hi,
Do you know if I can write in Data Memory of a PIC18F44J10???

I saw the datasheet that there are 768(Byte) but I do not find the register where I have to put the address and the data...


anyone can help me????

Hi,

Thats because its just blank ram memory.

To use it you have to address it - the most common way is to first assign a name to the 'register' or byte of ram you want to use to store a byte of info.

Once addressed you can then read and write to it by refering that registers name.

What are you coding in C, Basic , Assembler ? - sounds like you need a beginners guide to help you with the fundamentals.

I'm using C18;
I just have a library guide, but I didn't find the istruction set,
I know that there is one register for address and one for data, ...... but where???

Hi,

Assembler is my main language, but think these links will help you get going.
