PIC16F690 - 24LC08B: they won't talk...

[sayzer]

Sayzer,

There IS a
DEFINE OSC 8
in my program, i just forgot to paste it...

Here are some things i will have to check/do:

- solder a 8 pins socket on a protoboard instead of breadboard and solder connexions

- use 2k wpu only on sda instead of a 4.7k wpu on each scl and sda

- swap with another pic16f690 in case the one i use is defect

- swap with another 24lc08b in case the one i use is defect

- try a huge pause 50 instead of pause 5 after the i2cwrite in case it is a timing problem

- declare the eeprom address variable as a word instead of as a byte

- declare "eep_address" instead of "ep_address" (i wonder how i didn't see this typing error!)

- try to program a specific value in byte 0 of the eeprom using my pic-pg2 programmer and see if i get this value back with an i2cread

besides this i don't se what i can do...

How did you NOT get an error then?

Also, when you change your code after you asked some questions about it, it is difficult to follow.

Paste a new one with your modifications, so that we can see what the difference was.
