well i am about 70% of design down the rd ,
custom matrix keypad is made
prototype pcbs for the design done,
modules purchased etc


controller with the display is started being coded and that when started to see a lack of usable mem when even assigning the pin var with only 1k of mem on the 16f1947

which come to the conclusion that i may have made a error using the 16f1947, although the looking at other 8 bit chip alternative of 18F67K22 appears to be pin to pin compatable with the the 16f1947 , but with 4k of mem . 128k of program data internal 64mhz , i am thinking i can easly add a sram using a spi ( yes hardware spi is now the option of choice.to the spi port ,if i run short of buffer space for the larger mono graphics display ???

it seems the 24F series is not supported by the picbasic form what i can see??
also the cost of the 16bit chips with larger usable mem of 8k is way more than adding some extra ram, although more speed is alway nice !!
