Post by thread:[PIC:] Which pic to use?

Hi, I'm making a really powerful scientific calculator and I need to know which kind of PIC to use. The program I'm writing is fairly big (a whole equation parser, lots of other stuff) - maybe about 15 pages long and is in C. The pic needs I2C for serial eeprom i/o, enough i/o for a small lcd and a large matrix keypad which i think should'nt be an issue just fitting my code in. It also needs to be under $10. Will my program fit on a Pic16xxx?

As a start look at Microchip's free tool called the PIC Calculator. It lets you parametrically select devices by filtering out wanted or unwanted features. Cheers, -Neil.

How about you compile it and see how much code is emitted? Best regards, Spehro Pefhany --"it's the network..."
