=== JC30 connector ===
This JC30 is used to connect a camera for capture video or image. Omap have the processing capability to connect RAW image-sensor modules via this connector don't have mux capabilities.
J970 There are some peripherals than can be connected to JC30 like like CAM, SSI and CSI, but is not used in this how-to implement a keypad. It is controlled by TPS65950, this method avoid reduce Omap proces capabilities. TPS65950 send via I2C1 all GPIO are the interrupt requestdefault peripheral. Their characteristics are:<br>
- Can handle up to 8 x 8 keypads, IGEPv2 can handle up to 4 x 4 keypads.<br>- Optionally, you can decode via Omap software.<br>- Event detection on key press and key release.<br>- Multikey press detection, can detect up 2 keys Before use this connector be careful at the same time.<br>- Long-key detection on prolonged key press.<br>- Programmable time-out on permanent key press or after keypad release. these points:
More information in TPS65950 datasheets- Pad 1 can be used to power down wifi module if RD41 is short circuit, replace RD42 for this porpouse.<br>- Pad 2 can be used to reset wifi module if RD43 is short circuit, replace RD44 for this porpouse.<br>- Pad 21 can be connected to I2C2_SCL, that wire is shared with J990 connector and I2C2_SCL peripheral. Placing/replacing RC13 for tis porpouse.<br>- Pad 22 can be connected to I2C2_SDA, that wire is shared with J990 connector and I2C2_SDA peripheral. Placing/replacing RC14 for tis porpouse.
