Within the same loop, the firmware checks the RxPacketReceived flag (set by an interrupt service routine). If true,
indicating there is data waiting, the firmware lights the red and green LED according to the value received.
// receive from other node, display value with LED's
if(RxPacketReceived)
{
ppPhyGetRxPacket(&RxPacketLength, RxBuffer);
switch (RxBuffer[0])
{
case 1:
LED_GRN = ILLUMINATE;
LED_RED = EXTINGUISH;
break;
case 2:
LED_GRN = EXTINGUISH;
LED_RED = ILLUMINATE;
break;
case 3:
LED_GRN = ILLUMINATE;
LED_RED = ILLUMINATE;
break;
default:
LED_GRN = EXTINGUISH;
LED_RED = EXTINGUISH;
break;
}
}//if RX
} //while (1)
The firmware sits in this loop indefinitely and waits for a transmit request keypress or an incoming packet.
This is a very simple code example. You may extend this example to suit your application by:
Adding power management: See code examples in C:\SiLabs\MCU\Examples\Si101x\SleepMode to place the
MCU core in low-power, waking up on keypress, or a real-time clock.
Making a measurement with the ADC: See code examples under C:\SiLabs\MCU\Examples\Si101x\ADC.
Adding communications via UART or SPI: See code examples under C:\SiLabs\MCU\Examples\Si101x\UART
and C:\SiLabs\MCU\Examples\Si101x\SPI
Note that these code examples are installed as part of the Silicon Laboratories IDE installation.
