failing to write a float value, but don't know why about fram_i2c

[RobTillaart]

Thanks for reporting the issue.
Have no computer nearby (phone only) to investigate.
Will get back as soon as I am operational again.

I think i found the solution myself, a float can't be written to an u_int32_t it has to be writtenand reading as an object.
it know looks like it is working.

[RobTillaart]

Yes floats are not directly supported, writeObject() is the way. As float is a basic datatype it might be usefull to have a writeFloat(address, float) to simplify the usage. And a read too of course.

[ageurtse]

That could be nice, but with the use of writeobject and readbject it does the trick also.

@ageurtse
Working on a 0.4.3 release with writeFloat() and readFloat() support in the develop branch.
I encounter problems with build-ci which are under investigation so I will not merge soon.
But you are welcome to give the code a test drive (unit tests are OK).

would love to try it out from within esphome, but don't know how to load the develop branche so i could test it.
after i found the solution for that i try and report back.

esphome is based on platformio
currently i add i like this

tryed instate of 0.4.2 develop

 libraries:
    - "Wire"
    - "robtillaart/FRAM_I2C@^0.4.2"

Green code button ==> local tab ==> download zip

The develop branch is not located on platformio so think it will be beyond trivial.
(not familiar with esphome ==> need to plan some R&D time...

if you are into home automation, you should realy look at esphome and homeassistant

managed to install the develop tree, reading and writing a float looks good to me.
only thing for me, a float is 32 bit, why do you check for the size ?
this is because if i write a value to the second position it is in my case on the 5th byte.

[RobTillaart]

I use the sizeof() to minimize the "magic numbers"
The call sizeof(fliat) is self documenting so it provides the reader of the code the meaning of the parameter.

[ageurtse]

Realy would like to try but don’t now how to select the development enviroment from within esphome (platformio)

[ageurtse]

I managed to load the library and it all run’s fine.

so i see no need to not push it to the master

[RobTillaart]

Thanks for testing, will merge tomorrow,
Still I need to have my build-CI running 100% as that saves me a lot of time .

@ageurtse

• added writeDouble() and readDouble() to the develop branch. This is for the boards that support 8 byte doubles.
• created a PR
• escalated the bug in the build-ci to the "build team"
