+# Raspberry target
+
+This is a target to build OpenSky and run using a raspberry pi, with an CC2500 chip connected directly to the spi bus. Using the raspberry target is an easy way for experimenting with the code.
+
+OpenSky requires good timing to be able to do frequency hoping correctly, but an ideling raspberry pi seems to do just fine.
+
+Here is how i connected up my module:
+
+<pre>
+Raspberry Pi V2        CC2500
+
+16 GPIO23              GDO2
+17 VCC                 VCC
+19 MOSI                SI
+21 MISO                SO
+23 SCLK                SCLK
+25 GND                 GND
+
+03 GPIO02              LNA (Optional, if your chip have LNA)
+05 GPIO03              PA  (Optional, if your chip have PA)
+
+37 GPIO26              BIND (pull up to enter bind mode)
+08 TXD                 SBUS (output using hardware uart)
+40 GPIO21              PPM  (software bit banged, low quality)
