TI-NSPIRE calculators
|

|
||||
Required properties:
|
||||
- compatible: Compatible property value should contain "ti,nspire".
|
||||
CX models should have "ti,nspire-cx"
|
||||
Touchpad models should have "ti,nspire-tp"
|
||||
Clickpad models should have "ti,nspire-clp"
|
||||
|
||||
Example:
|
||||
|
||||
/ {
|
||||
model = "TI-NSPIRE CX";
|
||||
compatible = "ti,nspire-cx";
