I don't think it's normal that even if the init failed, the message is still sentWhat could it be ?I've searched in the library and can't find why the init returns false.
Anyone has an idea ?
Connect to a proper 3.3V device such as a £1.50 3.3V Arduino Pro Mini. If it fails init, there is no device found, see #2 for the reasons why this may be.
I use logic converters so the voltage is at 3.3V instead of 5V
What's #2 ?
Have you used a scope to check the levels and edges on both sides of the logic converter ?Post 2 in this thread.
I noticed something stupid
I don't get the first sentence, what do you mean ?
