Pre-Requisites for Building subg_rfspy

[sdcc] (http://sdcc.sourceforge.net/) package is required for this build.

sudo apt-get install sdcc

UART on RileyLink

Perform the build. The output file will be stored at output/uart1_alt2_RILEYLINK_US/uart1_alt2_RILEYLINK_US.hex

make -f Makefile.uart1_alt2

Perform the install:

make -f Makefile.uart1_alt2 install

UART/SPI pins exposed on cc1110 debug header:

PIN - SPI_alt2 / UART1_alt2
P1.4 - CT / SSN
P1.5 - RT / SCK
P1.6 - TX / MOSI
P1.7 - RX / MISO

Radio Frequency Selection

This code defaults to building firmware that works with US-based pumps. If your pump model number ends with 'WW' then you need a 'WorldWide' firmware:

make -f Makefile.uart1_alt2 RADIO_LOCALE=WW

cc111x UART1_alt2 connected to the Intel Edison UART_1

P1.4 - CT / SSN -> UART_1_RTS (GP129) (pin 63)
P1.5 - RT / SCK -> UART_1_CTS (GP128) (pin 65)
P1.6 - TX / MOSI -> UART_1_RX (GP130) (pin 61)
P1.7 - RX / MISO -> UART_1_TX (GP131) (pin 46)

UART on the WirelessThings ERF stick

Perform the build. The output file will be stored at output/uart0_alt1_SRF_ERF_US/uart0_alt1_SRF_ERF_US.hex

make -f Makefile.uart0_alt1 BOARD_TYPE=SRF_ERF

Installation is bit more complicated, as you will need to attach connectors to the SRF pins manually (you can't use the wiring points on the board itself).

This XRF blog post maps cc-debugger connector to the XRF pin names.

However, the XRF pins are not the same as the SRF pin locations. For that, you can use the SRF OpenMicros Data to map things to the correct ERF locations.

  • SRF Pin 5 - DDATA (also known as DD)
  • SRF Pin 6 - DCLOCK (also known as DC)
  • SRF Pin 9 - 3.3v (also known as VDD)
  • SRF Pin 10 - Ground (also known as GND)
  • SRF Pin 15 - Reset

To install the firmware:

make -f Makefile.uart0_alt1 BOARD_TYPE=SRF_ERF install

USB on support on TI cc1111 USB stick (CC1111EMK868-915) AKA "Don's Dongle"

make -f Makefile.usb_ep0 install

Shows up as a serial device on linux.

CCTL Support

If you have CCTL on your device stick, you can re-program the firmware without requiring the cc-debugger. To compile firmware that's compatible with CCTL, set the CODE_LOC and CODE_LOC_NAME parameters:

make -f Makefile.uart0_alt1 BOARD_TYPE=SRF_ERF CODE_LOC=0x400 CODE_LOC_NAME=CCTL

Then, compile the cctl writer program:

cd /where/you/want/the/cctl/code/to/live
git clone https://github.com/oskarpearson/cctl.git
cd cctl
git checkout 24mhz_clock_and_erf_stick_hack
cd cctl-prog
make clean all

Then connect the ERF stick over the serial port (normally /dev/ttyUSB0), and write the firmware:

./cctl-prog -d /dev/ttyUSB0 -f /path/to/subg_rfspy/output/uart0_alt1_SRF_ERF_WW_CCTL/uart0_alt1_SRF_ERF_WW_CCTL.hex
Waiting 10s for bootloader, reset board now

Reset the board by disconnecting the +ve lead, and you should then see:
