SMCD Series
Pushwheel Switches, Mini, Front Mount
SMCD Series have large visible readout characters despite it's small
size. This popular family is used in measurement and test
instrumentation for range setting, data programming and count
controlling; and in communications equipment for digital tuning. The
simple, reliable bi-direction pushbutton mechanism permits rapid
changes to either higher or lower numerical settings. Instrument-grade
performance and long service life are enhanced by the heavy gold
wiping contacts. Large readout characters are protected by dust-sealed
windows. Snap-together grouping and snap-in panel mounting
minimize installation time and cost. SMCD models have snap detent
with slight audible click.
SMCD bi-directional code switches may be easily assembled into
groups of any number. The tabs or pins of one decade section press fit
into the holes in the adjacent section. Spacers and end mounting plates
may be included in the same manner as desired.
Groups of SMCD switches with end plates snap into panel holes of the
recommended size and are retained by plastic clips. Again, tools and
additional hardware items are not required.

说说大家是如何做按键检测的
一般检测一个按键可以这样做:while(1){ SysCtlDelay(SysCtlClockGet()/30); //延迟100ms temp=GPIOPinRead(GPIO_PORTD_BASE,GPIO_PIN_5); if(temp==0) { temp=1; SysCtlDelay(Sys ......
