Implemented a better HRF_readfifo_burst. ...

This has facilities to read a fixed payload, or a count byte preceeded payload.

Framework for FSK receive in place

Started working through new FSK receiver architecture

Tested with MiHome adaptor plus, new FSK transmitter works fine

FSK Transmit coded, ready for test

Restructured switch.py so we have a tx-only test. ...

This is in preparation for pushing the FSK transmitter into radio.c

Refactored so that we can create a tx-only switch loop tester. ...

This will be useful for integrating a new FSK transmitter without receiver

Tested on Raspberry Pi, switch, monitor, and legacy work with spi scaffold

radio2.py offers temporary spi interface for radio.py ...

Tested on mac only.

Build of radio_rpi.so updated

Removed experimental arduino work

Fixed failed merge

Merge branch 'long-tx'

Improved configurability of message repeat patterns. ...

Tested with different repeat lengths.
Optimum seems to be 8 inner, 1 outer transmits

Turned off TRACE on raspberry pi build

Tested with learning mode. ...

Works with all 4 switch patterns.
Can now independently switch 4 switches.
Some occasional RF reliability problems that need measuring.

Implemented mode switching logic. ...

This is so you can just say radio_standby()
Then radio_transmit() and it pops to standby at end of transmit.
Or, radio_receive()
Then radio_transmit() pops back to receive at the end.
Also massive tidy up and trimming out old comments.

Improved flow of code, specifically radio_transmit() ...

Pushes previous mode and restores at end of transmit.
This should auto-return to standby or receive as appropriate.
This will make it easier to implement mode hopping schemes later.

Simulation gets further now due to gpio_sim detection

Started design of new long payload transmitter

Initial design of new radio transmit scheme

radio_rpi.so now built as part of the pi build process ...

legacy.py now uses the prebuilt radio_rpi.so

encoder now adds preamble. ...

lecacy.py now uses new C radio driver

Tested radio2.py on Raspberry Pi, now works with OOK transmit

Tiny tidy up

Renamed encoder_test to be consistent with other testers

Wrote radio2_test.py as a python OOK tester for new radio.so lib

radio2.py ctypes wrapper ready for testing

Preparations for new radio interface added to the architecture

Tweaks to radio_test.c layout
