2 questions

Hello.

I have two questions:

1. Can i write data with I2C protocol from IOIO setup event, or just from the loop event?

2. I connected the IOIO to some device with I2C, my device start sends data to the IOIO from MSB digit to LSB digit.

   did i need to soft the digits after that the IOIO read them?

Yes. You can do it from setup().

Not sure what you mean by "soft the digits".

Thanks.

About the second question: for example, my device start sending this binary nubmer - 10000000, which the '1' is the first bit was sent.

what the IOIO respose byte buffer will receive, 00000001 or 10000000

I2C is always MSB-first I believe. So 10000000 is 0x80.

Thank you.
