I have the pin physically grounded and verified with meter. All address bits are grounded, chip has 3.3V across the IC pins directly. Verfied pin paths to SDA and SCL.
I also changed the chip once to another thinking it was a hardware issue. Same result. I'll give the Atmel a look, I don't have a programmer piece that would support this device. I only have a DIP and PLCC programmer. I should pick up an soic narrow and wide, but they are like $80 each! I figured it has to be the programming or something I'm not reading in data sheet right. Any other thoughts? Thanks for the input. Chris |
