The Sensor Terminal Board is a carrier board for the radio controller board family. The transceiver wiring fits the common RCBs. The wiring of the radio and the ATmega is shown below:
AVR RF230
--- -----
PB4 --> SLPTR
PD6 <-- CLKM
PD4 <-- IRQ (ICP1)
PB5 --> RSTN
PB0 --> SS
PB2 --> MOSI
PB3 <-- MISO
PB1 --> SCK
The STBxxx has memory mapped LEDS and Keys.
KEY: PE5
LEDS
You can select between using the LEDs on the RCB or on the STB.
In order to use the RCB LEDS, you have to define the macro USE_RCB_LEDS.
The LEDs on STB have a write-only memory interface, so we can't read back the LED status.
So we need to have a shadow register, which stores the current LED state.
Since the board interface consists only of a header file, we use register
GPIO2 on ATmega1281 for shadowing, because it would be hard to ensure the
single instantiation of a global variable from a header file, which is used
in many module files.
