arraywrite takes too much memory, is there any way for optmisation?

What device are you using?

[richard]

nothing has changed since last time you asked the same question

I'm using PIC16F1939, as the biggest memory (16K and fastest (32mhz) in 16F family.
I just came to idea - since reading external EEPROM is quite slow
what if I use some SRAM chip, with parallel access, like CY7C199, copy data from EEPROM to it at startup, and access it as required?

[richard]

15 address pins
8 bidirectional i/o pins
r/w control pin
oe pin
ce pi
hope you don't want the pic to do much else other than be a pin jockey for all them controls

and you think that will be easier to get going than learning to use flash memory

[CuriousOne]

Yes it will take a lot of pins.
I'm using I2CREAD/I2CWRITE w/o any issues, but it is slow.

Flash memory is more manageable as Richard noted.

Observe how selected PIC is controlling read/write pages and do it nice and fast.
