#175186 - one more doubt Responding to: ???'s previous message |
Up till now i have been reading and writing directly to the glcd. But our project mentor told me use a buffer instead. (i.e. to write everything on a buffer and update the screen using that buffer).
As we are using a 128x64 glcd, i need to use a buffer of size 1024Bytes. But the RAM available with p89v51rd2 is only 1024 bytes long. Where should i store this buffer? is it possible to somehow use the Flash? or should we use external memory? |
