Manolis Surligas e79e98fbd8 AX.25 support at the UPSAT FSK encoder/decoder 2016-04-29 21:43:09 +03:00
Manolis Surligas 382e5a615b Start the AX.25 integration into UPSAT FSK framing 2016-04-26 22:21:42 +03:00
Manolis Surligas 10d4519bcb Implement the whitening and de-whitening process for the UPSAT
The data whitening and de-whitening mechanism is implemented using
lookup tables for fast processing times. The implementation is quite
generic and modular supporting user defined polynomial masks and seeds.
The lookup table is created during the initialization without any
runtime overhead.

Manolis Surligas 34ae5f143b Fix CRC16 calculation and transmission
The CC1120 uses the non-reversed version of the CRC16-CCIIT. Also the
CRC16 is transmitted in network byte order

Manolis Surligas 0c354da145 Finish the FSK frame encoder for the CC1120 2016-04-08 21:41:21 +03:00
Manolis Surligas e80486cc07 FSK receiver for the CC1120 works!
The FSK receiver of the CC1120 can now retrieve the frame that is
transmitted over the air. The next step is to provide the support for
data whitening and Manchester coding.

Manolis Surligas 228fd37014 Implement the UPSAT FSK encoder block.
Fix also a small bug at the UPSAT FSK decoder block.

Manolis Surligas 4b3b08f200 Finished the FSK frame acquisition. 2016-04-05 21:29:23 +03:00
Manolis Surligas bb57d63517 Continue with the FSK decoder for the UPSAT 2016-04-04 00:29:28 +03:00
Manolis Surligas 6ae7614af2 Start the FSK frame acquisition block of the UPSAT.
After managing to successfully receive raw bytes from the TI devboard
with the CC1120, its now time to pack them into a frame by searching for
the preamble and synchronizing with the known byte sync word.
