[[bc10]] -Contents #Contents * Summary [#r55d3834] > Since there is empty space on the original serial interface, the original interface is revised and added a power switch and two~ pushbutton switches are added. The new serial interface is connected to bc10 by the iPod Dock connector, but the lines of the~ connector are directly wired to these switches on the protoboard of the new serial interface.~ * Serial interface (with Switch) [#ace38622] ** Example 1 [#lbfb2e0f] > This section only discusses how to add several switches on the serial interface. Assume that [[Example 1 at bc10/serial interface:http://labs.beatcraft.com/en/index.php?bc10%2Fserial%20interface#p336d749]]~ has been completed and understood. For the information of the original serial interface, look at [[bc10/serial interface]]. *** List of Additional Parts [#k1da0460] > |Name|Quantity|>|CENTER:Specs| |~|~|Operation|Contact Rating| |Toggle switch|CENTER:1|Power on/off|20 ~ 400 mA| |Pushbutton switch|CENTER:2|Push Button|1 ~ 100 mA| CENTER:Wires (Recommend 0.26mm diameter single wires for connections)~ *** How to Assemble [#g489e6de] > +Part of serial interface is assembled (but leave the cover of connector open). +Place Toggle and pushbutton switches on the Protoboard. +The point A of Toggle switch is connected to GND and #28 at J1. As GND and #28 create short circuit, power of bc10~ is turned on. +The point A of one pushbutton switch, which is used for USER, is wired to #24 and #26 at J1. As these causes short~ circuit, bc10 recognized that USER button is pushed. +The other pushbutton switch is allocated for RESET. The point A of this pushbutton switch is attached to GND and #22~ at J1. When the button is pushed, GND and #22 are short circuited, and bc10 is reset. +The connector cover of J1 is fully assembled, then the process is finished. *** Exterior [#o9dea842] > -Whole connector --&ref(CIMG8279.JPG,,25%);~ -Inside the connector (J1) --&ref(CIMG8280.JPG,,25%);~
