hi,
are the eeprom and the wire library in the arduino ide supported?

Hi,
The wire (I2C) has been tested. By EEPROM library do you mean the functions that access the AVR's on-chip 512 bytes of EEPROM? The TC275 has 128KB of data flash that can be used in a similar way. However we have not implement the read(),write(),update(),get(), put() & EEPROM[] functions yet. If this would be useful for you, we can look at them next.

Hi,
yes that would be helpful. Alternatively, an example of how to use the flash would be helpful, too.
Thank you!
Bye

Hi,
can anyone say when the EEPROM library is implemented?
I would now program my own flash read and write functions in my project,
but if e.g. in one, two weeks EEPROM is supported, I could also wait a bit :-)

Hi,
We'll do it next. Hopefully < 2 weeks! |

Hi,
Thanks for the quick news.
That would be great. Then I do not have to deal with it.
This would be quite a challenge for me :-)

Which EEPROM functions do you need? How much data do you need to write to EEPROM,?

And how often do you want to write to it?

Hello,
I only need EEROM.write and EEPROM.read.
Hard to say how often is to be written. I think once a day.
I know that the flash has limited write accesses.
There will probably be more write accesses during development.
I think 1-2kB would have to be enough.

Hi,
The 384kbyte DFLASH will allow 125k write cycles and 750k erase cycles. However these are worst case figures for automotive use at -40 to + 125degC over 20 years use. In reality (and for development use) the DFLASH is far more durable.
How many bytes will you want to write?

We should be able to release this next week. There is a lot of testing to do as unreliable EEPROM is worse than none at all!

Hi,
thank you for the eeprom lib.
It works perfectly 😄
Bye
