Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

On Raspberry pi there is a utility in i2c-tools to map all the i2c devices connected. I am a newcomer to MMBasic and I was wondering if anyone written something similar to take the hassle out of trying to find conflicting addresses?

It is trivial to do in Basic

[code]
Sub i2ctest
Local integer i,j
I2C open 400,1000
For i=8 To &H77
I2C read i,0,1,j
If MM.I2C=0 Then Print "found address ",i
Next i
I2C close
End Sub[/code]
