Effing brilliant! (Someone please remix it so the vocals are more distinct!)
the point is there is not any new defined I2C. So does not matter if I put that resistors or not. Or it does matter and I do not know!
it is still black. because it does not considered as a header.
Question: If this command of #include <i2cMaster.h> really defined a new couple of I2C pins, and I did not use resistors, what may happened?
Question: is 4.7 kohm is enough for pull up resistors? how should I put it?
You always need one set of pull up resistors on each I2C bus.
put in the line in the keywords.txt file
I dont think always!
I dont think always! at lease for pins A4 and A5, as you can see here:
what does Quoteput in the line in the keywords.txt filemean?
I need to copy I2C library in the main library.
