Hi,
Does anyone "make" a PCF8574 with PIC 16F84 ? This PIC is obsolete, but I'd like "convert" it in 8 I/O over I2C protocol.
I looking for this source asm.
Thanks a lot.

Arrow sells the original part for $1.79. According to Philips, they have them in stock. Sound a hell lot cheaper to me than writing an emulator on a chip that can hardly keep up with 400kHz I2C.
