Hi,
Iam trying to get the code from JeeLib for Software I2C to run on my Arduino Mega.
I already managed to change the Digital Pins 4,5,6 (SDA) to 22,23,24.
My Problem for now is that I cannot change the analog Pins (SCL) A0,A1,A2 to for example A11,A12,A13.
I am trying to get 2 Sht21 work simultaneously with I2C but both using the same address, so I need to use Software I2C.
With the premade (SCL) A0-A2 both Sensors SHT21 working quite fine but I also want to use an LCD Shield and in this case A0-A2 are blocking the shield pins.
This is his build but i want to use an arduino mega 16u2 instead.

You can get the hole JeeLib Library for SHT21 from here (iam working on the Ports.h lib)

This is my bit modified code.
As you can see i changed the digital ports from D4,5,6 to D22,23,24 and it is working
But this is not working with the analog pins and i donw know why :/.
Hope you guys can help me to change that library code to work with other analog pins.
Thank you very much.
