An ICSP programmer such as a Bus Pirate v3.x is needed to flash amforth onto the Arduino Pro Mini.

Wire it up like so:

BP        Pro Mini
GND  ---  GND
3.3v ---  VCC
MOSI ---  DIGITAL PIN-11
MISO ---  DIGITAL PIN-12
SCK  ---  DIGITAL PIN-13
CS   ---  RST

Then:

$ cd code/wetland-mcu-nodes/
$ make get                                # download dependencies (amforth and avrassembler)
$ make pro-mini.hex                       # Assemble the base of amforth for the Pro Mini.
## Wire up a Bus Pirate v3.x to a 3.3v 8MHz Arduino Pro Mini as described above.
$ make pro-mini.bak                       # Back-up the factory EEPROM and flash contents.
$ make pro-mini.era                       # Wipe the MCU flash.
$ make pro-mini                           # Upload the firmware using the generated hex file.
$ make pro-mini.fuse                      # Set the MCU fuses appropriate for amforth.
$ make pro-mini.clr                       # Clean (except for backup and source files).
## Unwire BP. Wire up your USB-UART adaptor of choice.
$ make pro-mini.once PORT=/dev/ttyUSB0    # First upload this once. Replace ttyUSB0 with your device name.
$ make pro-mini.frt PORT=/dev/ttyUSB0     # Upload frt files. Replace ttyUSB0 with your device name.
$ make pro-mini.term PORT=/dev/ttyUSB0    # Enjoy!

Repeat for each sensor node.

The nRF24L01+ now output an unmodulated centered carrier.

On another:

Remote control will require more battery power, so it is advised to switch to periodic mode when deployed.

periodic mode: sleep & awaken for periodic measurements & transfer

Interactive querying and programming is unavailable during periodic mode until the next awakening.
