J970 connector
J970 is used to implement a keypad. It is controlled by TPS65950, this method avoid reduce Omap proces capabilities. TPS65950 send via I2C1 all the interrupt request. Their characteristics are:
- Can handle up to 8 x 8 keypads, IGEPv2 can handle up to 4 x 4 keypads.
- Optionally, you can decode via Omap software.
- Event detection on key press and key release.
- Multikey press detection, can detect up 2 keys at the same time.
- Long-key detection on prolonged key press.
- Programmable time-out on permanent key press or after keypad release.
