Title: probleme :connecting more than one MOD-IO together with olinuxino A20
Post by: redwane on May 29, 2015, 12:42:16 PM
Hello,
hello,
I want to connect multiple MOD-IO card with olinuxino A20, for that I need to change the I2C address, I follow the steps in the manual of MOD-IO :
# apt-get update
# apt-get install i2c-tools
To change address to 0×22:
# i2cset -y -f 2 0x58 0xF0 0x22[/color]

but the address does not change
Any ideas?

I have done this before and it worked OK.


-Can you see the board at 0x58 using i2cdetect command?
-I think you need to power cycle the MOD-IO after changing address.
