using WireWrapper on MKR1000 with SAMD21 core about wirewrapper HOT 1 OPEN

Hello,

sorry for long time in answering.

FRAM components doesn't need real init process, this step mainly initializes the I2C_SLAVE struct with I2C address, speed and register size of the I2C slave.

Some other components needs an initialization phase sending some parameters before it works the desired way.

Can you please provide the reference of the analog I2C chip you're trying to use? It would help giving some hints on how to properly set it up.

You can declare the slave as you mention and giving reference to it when calling init with proper parameters (address 0x5B (beware if the address is already shifted or not), communication speed, and the size of it's internal registers (8 or 16b)).

Yes, you can see ci2c mentioned, but it's refering to another lib in my account (dedicated only to AVR µcontrollers). ci2c is coded to work directly with AVR registers to set up and make the communication work; SAM families uses different registers, WireWrapper as it's name states uses Wire library from arduino, but providing the I2C_SLAVE abstraction layer.
This means code will be the same in a sketch, but portable between different arduino platforms when WireWrapper.h is included (which is not the case with ci2c).
