** 30-pin Connector [#peac3ddf]
>
- List of signals that 30-pin connector (the picture of Main Board Front View No.8) handles
-- Stereo Audio Input
-- Stereo Audio Output
-- S-Video/Composite Video (Exclusive)
-- Serial Console
-- Power Switch
-- USER Button
-- RESET Button
>
- To handle several output signals simultaneously, use an iPod/iPhone connector, which is differ from commercially~
available iPod/iPhone accessories. Wire the specified pins through the connector. To control the power switch and~
reset button of bc10 externally through the 30-pin connector, please make sure that the switch at bc10 turns off.~
This is a two-part example, which shows how to connect serial console and how to control external RESET and USER~
buttons, and power switch simultaneously. The example is listed [[here>bc10/serial interface]] (making a serial interface) and [[here>bc10/serial interface with switches]] (adding~
external buttons and power switch to the interface).
>
- Caution: all 30-pin connecters are neither identical nor compatible. Commercially available iPod/iPhone accessories~
should not be connected with this 30-pin connector of bc10 in general. It is true that some accessory may work with~
the 30-pin connector as some pins and functions are for bc10, but it is very seldom and requires a lot of homework~
before connecting the two products. Do not connect the accessories which employ the function of Firewire, these~
accessories may damage bc10.
** Slot for Expansion Board [#nfd00e99]
>
- List of signals, which both slots (the picture of Front View #12) deal with
-- GPIO
-- Keypad
-- UART1
--I²C (2ch)
-- SPI (1ch)
>
- The signals of GPIO and keypad are not shared between the right and left slots. The right and left sides of these ports~
are designed to be independent from each other. Other output signals are share between the right and left slots.~
- Slots for Expansion Board output the signals at 1.8V CMOS level. If a board connect with the slot at other than 1.8V,~
it requires a logic voltage level converter to adjust voltage.~
