Note: Reconfigures as OOK regularly, unneccesarily now

Fixed bug with OOK struct size in hrfm69_test.c

Finished coding radio_test and radio(tx) module

First pass of spec'ing radio.h/c and radio_test.c

Can now reliably turn energenie switches on and off with hrfm69_test.c

Coded a better payload transmit test routine for OOK

Started coding up new burst transmission scheme

Started to write another test case to blurt out OOK energenie messages. ...

This is only a test case.
But it has highlighted a whole load of discrepancies in the original C
code to do with payload length calculation, and the 'magic' zero byte
at the start of the buffer for stuffing the SPI register address in.

Tracked down the 'long sync bit' problem. ...

It's due to the HRF always preceeding each packed with an extra 01 at start.
Existing driver code sends 'chips' to prove this.
Looking like a preamble of zeros will be required to make this a non issue,
and then generate the real 80000000 preamble as part of the payload.

Got the radio chirping again after a long period of not working at all

hrfm69_test.c now sending a tone. ...

Discovered that 1/5 times it sticks waiting for TXREADY.
This might suggest an unresolved sequencing error in startup.

spi_test.c can now read back the version number of the HRF69 chip

Simple GPIO tester works on Raspberry Pi (flashes LEDs on radio)

Built a simple C test harness to start testing the radio with

Baud rate for OOK increased to 4800bps to bring in line with latest Energenie builds. ...

Sync pattern now recognised correctly as 0x80,0x00,0x00,0x00
Switching is eratic, but learning always learns.

Regular schedule for switch1 transmit test

Added feature to test a single switch repeatedly

Added green LED around transmit and receive transactions. ...

This is useful for measuring total on-air time on logic analyser

Experiments on Arduino with larger register writes and FIFO write ...

Getting some corruption on the Arduino RAM buffers.
Logic analyser traces show that the tables are getting corrupted
and the wrong data is being written to the radio registers.

Managed to write/read the mode register from real RFM69 with Arduino

Reset, select, write working on Arduino

SPI being driven on Arduino

Got simple 5 pin interface with GPIO working on Arduino Pro Micro

Preparations for wiring up to Arduino

A 'go for broke' OOK transmitter added to hrf69_test

Implemented most of hrf69.c write and read functions

HRF_write_reg written

Factored out all stdio from all testers and code

Mock read and write test working for radio register

Proved that we can read a register back from simulation

First pass at writing a test in hrf69_test.c

Marked the interface queries in HRF69.h

First attempt at specing out implementation of HRF69 based on python

spi_test working on Mac

Refactored delay into a platform module

gpio_sim working on Mac

Wrote GPIO simulator in a mostly platform independent way.

Framework in place for Arduino GPIO and simulated GPIO

GPIO is now tagged as RPi specific in build process

Created file architecture for arduino build

Started refactoring

Moved all C into a drv folder.

First pass at defining hrf69.h and radio.h interfaces

Started to refactor code into C

Pre-factoring work done prior to pushing more code into the C domain.

Tweaked payload format further. ...

Reset all devices and re-learnt the house code
Can now switch all devices on and off, together, and independently.
legacy.py test code now demonstrates this in a loop

Added a test mode to test all 16 patterns of legacy control messages. ...

Run legacy.py and try numbers 0 to F in learning mode.
In theory you should be able to select 4 different switch addresses
plus an 'all addresses', but I can't get this to work on my 7 plugs,
they all respond as switch number 1 regardless of what code I send
in learning mode.

Attempts to get multiple device addresses working. ...

Seems to be a discrepancy between documentation and sample C code.
Stopping here until I get this clarified.

Fixed legacy import errors

Renamed modulator as encoder

7 legacy adaptors now turning on and off with this trimmed code

Improved reliability of syncing of OOK messages

Got old code working again. ...

Looks like the extra bytes inserted by the buffer bug actually make it work.
This is probably related to sync bytes

Merge branch 'master' of https://github.com/whaleygeek/pyenergenie

Brought back old test code that was working

More experiments with payload timing

Corrected sync preamble. ...

Brought in original legacy C code for reference

Tweaks to legacy learn feature

Rewrote legacy.py to use new modulation code. ...

Not yet tested on a real Raspberry Pi

Refactored modulator into a standalone module

Modulator tested and working

Wrote first pass of OOK modulator and test harness. ...

Still needs to be verified against the actual test messages

Slight improvements to timing of message transmission. ...

Still seem to get 'failed to send repeated payload to HRF' after a while
Suspect the FIFO is filling up or something.

legacy OOK test harness is working. ...

Note that sometimes we get 'Failed to send repeated payload to HRF'

Implemented a standalone switch exerciser demo. ...

Note this only really works with Adaptor Plus
(unless you seed the directory with your device id's first)

Started work on OOK support. ...

Ported C code into radio.py
Split out monitor and switch. Monitor.py is now just a monitor.
Switch.py needs more work to make it just a switch.
legacy.py will be a demo app for legacy (green button) devices.

Updated device database

Added rudimentary support for MIHO005 (HOUSE MONITOR) and MIHO013 (ETRV) ...

Fixed bug where eTRV sends an empty JOIN message that crashed the code
Added some extra fields to the CSV to support apparent power for House Monitor
Note: Voltage scaling on house monitor is incorrect.

Removed and tweaked a lot of trace messages to make it less noisy

Added missing file Timer.py

Added a simple data logging to CSV capability

Added RESET at start to reset the radio to a known clean state. ...

Added a SWITCH ON/OFF message every 5 seconds.
Re-tested and reports now seem to be a reliable 10 seconds.

Now builds a dictionary of seen devices.
Monitor FFFFFF messages removed, not needed.
Catches bad payloads and prints a warning rather than crashing.
Accepts and responds to a JOIN command.
