Post: I apologise in advance for not formatting code correctly but web browser won't play ball with "insert code snippet". I have two IO plus stacked on my Raspberry Pi but when I try to make IO Ports by assigning I2C addresses 0x22 and 0x23 I get the following error message. The first IO Plus has its solder bridges unchanged but the second IO Plus has bus1 with the "2" bridge connected and bus2 has "2" and "0" bridges connected .
