ocs-feedback

Firmware for that implements a feedback loop with the amc7812 ADC & DAC chip. The analog interface exposes 16 ADCs and 12 DACs.

A final hardware design is, as of yet, unfinished.

Derived from the ocs-base project.

How To Use

You

Just fork the repo as normal, remove/add libraries, write code, etc. Each library needs a CMakeLists.txt file in the top level of the library, and if applicable also in the {library_dir}/examples/ directory as well. See amc7812 for an example directory structure. Of course, you can structure your libraries however you want, but that will need to be reflected in the CMakeLists.txt files.

Me

github doesn't allow you to fork your own repo, so to make a new project that derives from this one I need to:

Create an empty repo on github with the desired project name, no readme/license etc.

$ git clone https://github.com/orthogonal-systems/ocs-myproject
$ cd ocs-project
$ git remote add upstream https://github.com/Orthogonal-Systems/ocs-base.git 
$ git pull upstream master

make your initial changes, edit readme, add/remove libraries, whatever

$ git submodule update --init --recursive
$ git commit -m "inital commit"
$ git push origin master

Changes to ocs-base can be applied by merging with:

$ git pull upstream master

Dependancies

What I've run it with. I need to improve this list.

make 3.81
cmake 2.8.12
avr-gcc (GCC) 4.8.2
avr-libc 1.8.0
avr-binutils
avrdude
arduino bootloader

Setup

$ git clone https://github.com/orthogonal-systems/ocs-feedback MyOCSFeedbackProject
$ cd MyOCSFeedbackProject
$ git submodule update --init --recursive

Build libraries

$ cd build
$ cmake .. ; make

Build & Upload to Uno

Build .elf and .hex files (stored in build/bin/)

$ cd build
$ make amc7812_test

Edit top-level CMakeLists.txt file to have the correct output port: SET(AVR_UPLOADTOOL_PORT "/dev/[your port here]")

upload to mega (you can do this without the previous make statement)

$ make upload_amc7812_test

Pinouts

Board pinouts are stored in "include/variants/{board_name}/". If your application requires board specific macros (like pin definitions), it is recommended to also place your pinout header in the relevant variant directory. See amc7812conf.h file from the included example library, for example.
