[[IONI]] drive will generate it's own SimpleMotion address (numeric address value starting from 1 on a multidrop bus) by measuring external resistors connected between ADDRSEL1 and ADDRSEL2 pins vs GND pin. These resistors are placed on motherboards like [[IONICUBE]].
==Address generation==
Final address of IONI drive is calculated by formula

<math>Address = DecadeAddres + SingleDigitAddress + SMO</math>

In above equation SMO is the {{param|SMO}} adjustable through [[Granity]] and it defaults to 0. Values of SingleDigitAddress and DecadeAddress depend on the resistors connected to ADDRSELx pins.

===DecadeAddress===
DecadeAddress depends on resistor between pins ADDRSEL2 and GND by following table:
{| class="wikitable"
|-
! DecadeAddress !! ADDRSEL2 resistor in Ohms (1% tolerance) !! Notes
|-
| 0 || open circuit ||
|-
| 10 || 5600 ||
|-
| 20 || 2700 ||
|-
| 30 || 1822 || Can be made by connecting 2700 and 5600 ohm in parallel
|-
| 40 || 3900 ||
|-
| 50 || 7200 ||
|-
| Force [[DFU]] mode || 11200 || 2x5600 ohm in series
|}

===SingleDigitAddress===

{| class="wikitable"

|-
| 7 || 11200 || 2x5600 ohm in series
|-
| Reserved, don't use || 22400 || 4x5600 ohm in series
|}
==Examples==
Resistors for various IONI addresses assuming that {{param|SMO}}=0.
