# 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:

|
37 GPIO26 BIND (pull up to enter bind mode)
|
|
08 TXD SBUS (output using hardware uart)
|
|
40 GPIO21 PPM (software bit banged, low quality)
