hello,
@Dexter Ind.:
I have problems to init 2 stacked BP3 accordingly
I now have the following 2 BP3 IDs:
// 0BE8A8C8504B5354392E314BFF0F2D39 // aka shield 1
// 8933FBBD514D32384E202020FF100F2F // aka shield 2
now I want the first number with the instance name BP3_01
and the second with the with the instance name BP3_02
what do I have to do entirely, I don’t get it?
Hey @HaWe, I modified the info.c program for your specific BrickPi3 IDs. Run the following program to make sure it’s working correctly, and then use it as an example:

printf(" 5v voltage : %.3f\n", BP3_02.get_voltage_5v());
printf(" 3.3v voltage : %.3f\n", BP3_02.get_voltage_3v3());
}
ok, now I see, it works, thanks!
As I observed, the mounting of my 2 BP3s can by shaky sometimes, having just 2 screws to mount at 1 side, the other side is loose.
In that case the info.c program terminates completely, prematurely, showing no BP3 information at all about either BP3.
So how can it be possible to modify the info.c program in a way to check for the 2 stacked shields, and show the one which is working, and list the other one which fails, by name, number, or FW address?
Sort of
"BP3_02, address 2, ID 8933FBBD514D32384E202020FF100F2F : not found"
:?:
Try this (I didn’t compile/test it):

works absolutely perfect, thank you very much!
