Even though THUMP is now installed and working in the #TrillSat project, I need it to actually do something useful, and so I'm adding more commands to my TRILLSAT-1 prototype.  On trillsat_bot.py, I've created a series of XMPP commands that I can issue to the ESP8266 (which is sent to the Pi over the UART).

The Pi then sends I2C commands to the LIS3DH so that I can change its parameters on-the-fly for testing:

cfg [0-255]     Set CLICK_CFG register to set click direction (1 is x, 4 is y, 16 is z, add for combos)
ths [0-255]     Set CLICK_THS register to change threshold (for changing the sensitivity)
limit [0-255]   Set TIME_LIMIT register
latency [0-255] Set TIME_LATENCY register (for changing the pulse width)
window [0-255]  Set TIME_WINDOW register

It also sends some I2C commands to the two ATtinys (Sawyer and Huckleberry) which run THUMP and SIMTHEO:

pulse            Instruct Sawyer to send a short haptic motor pulse for testing
pulsemode [1|0]  Set the morse_echo and morse_replay variables differently on the two ATtinys to enable haptic mode (1) or LED mode (0)
thump [1|0]      Turn the THUMP interrupt on or off

And on trillsat.c, I am now assigning commands to the various letters A-Z.  Hopefully 26 letters (plus an optional binary confirmation which allows 52 combinations) will be enough for me, and I won't need to add a second letter.  I can always add a second letter, which will take more time for the user to enter, to raise the number of combinations to 26^2 = 676 (plus that binary confirmation).  This is why Unix-like systems can get away with using so many two-letter commands--there are over 600 from which to choose.

Here are the haptic commands so far (but are tentative until I see how I like it):

X   Disable all power to the craft, including power to the ATtiny itself (if it is night, the craft will then be completely dead)
L   Turn on the ESP8266 (via its LDO regulator)
B   Turn on the 5v boost converter on Batt 2
Q   Turn on the Qi charger (important if the smartphone is dead and needs to charge to regain XMPP control)

I will add more commands later (and experiment with OFF or toggle commands) and release the updates to the TrillSat source code, showing how THUMP is actually working on the prototype.
