subg_rfspy
Pre-Requisites for Building subg_rfspy
[sdcc] (http://sdcc.sourceforge.net/) version >= 3.7.0 is required for this build. There is a docker image available for this purpose.
It's also possible to build it under Windows. The best way to do this is to:
- install SDCC version 3.7.0
- install Cygwin
- use Cygwin to install make
- Use cygwin bash to build the project
To install, you'll need cc-tool
Building and Installing
make -f Makefile.spi1_alt2 install
Building and Installing using docker
docker run -v `pwd`:/subg_rfspy ps2docker/sdcc_docker /bin/sh -c "cd /subg_rfspy; make -f Makefile.spi1_alt2
cc-tool -n CC1110 --log install.log -ew output/spi1_alt2_RILEYLINK_US_STDLOC/spi1_alt2_RILEYLINK_US_STDLOC.hex
Radio Frequency Selection
This code defaults to building firmware that is tuned to 916.5 Mhz. You can also build a 'WorldWide' firmware. This changes the default frequency to 868 and tweaks a few other settings.
make -f Makefile.spi1_alt2 RADIO_LOCALE=WW
