Hi, I'm trying to design a board while waiting for the ethernet chip to become available. The problem is the device are using SPI and I2C, how to connect this to a single PIC, and which PIC do you recommend (18F with enhance flash is preferable)? The problem is, I can only solder normal PDIP packages, no SMD parts. The following things must be connected to the PIC: - 1-8 x memory: 24FC512 (through I2C) - 1 x digital potentiometer: MCP42010 (through SPI) - 1 x ethernet: ENC28J60 (through SPI) - and there must still be enough I/O lines to connected a LCD display (datasheet: http://www.lcdchina.com/PDF/GDM1602A-5.pdf) Paul -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
