 		 #87550 - should I use Serial RAM for buffer?
Responding to: ???'s previous message
I compared my code with Michael's code in gLCD240X64 and found it to be almost identical for various read and write functions( we both must have read same datasheet!) I didn't implement the fancy fonts of yours and you have used the internal ram of silabs for LCD buffer. I'm thinking of adding a serial ram to add as buffer for the display, this way I will use only few pins for i2c which my board can afford. Is this a good idea or would it be a waste of time because serial ram is much slower in speed than normal ram?
