I2C with External Eeprom

[ruijc]

I guess i missed that one, sorry.

But thanks anyway for your help

Greetings,

While reviewing my code i changed the I2C lines from :

I2Cread SDA,SCL,CTW,mem,[x]

to

I2Cread SDA,SCL,CTW,mem.highbyte,mem.lowbyte,[x]

to make it work.

Sorry if i'm a bit stubborn ( just trying to learn ), but i re-made ( yes... re-made ) the search and as before almost every one mentions the I2C lines as follows :


I2cwrite SDA,SCL,CONTROL,ADDR,[DATA]

The only one that mentions to separate the address in high and low somehow did not worked in that case

My question is just to try to understand

Why is that the i2c line ( I2cwrite SDA,SCL,CONTROL,ADDR,[DATA] ) works with other pics ( yes...all my programs with 12F675 work ) and with the 16F88 does not ? Why with this pic i need to have the address separated with high and low byte ?

Also ( question for skimask )
In post # 7 you mention :

'cause I see a few flaws in your logic in the code written a few posts back.

Can you please point where the flaws are so i can take a look at them ?

Thanks

Quite frankly, if it works, who cares?
Actually, I don't remember the answer to that at the moment. I'll remember eventually...

You'll figure it out... Suffice to say there's just MUCH better ways to do some things, more reliable, faster, longer, stronger, and so on...

I've had to make some changes in my logic to work with the new I2C lines ( low/high address ) but still maintained the generic structure.

This was my priority #1

After checking if it works will study on those flaws .

I undestand your point of "if it works, who cares", but if we leave things like that we will never get to improve the codes to be more reliable, faster and shorter

Dont you agree ?

In the mean time, if you remember please let me know

Thanks again
