-# Relay_Tester
+# FG004_A(Relay Tester)
 
+## Description
+
+This embedded firmware for testing relay's, it uses an attiny404 to measure the
+make and break time of a relay.
+
+### Micro Controller Pins
+
+**ATtiny404**

+```
+
+The source code required to run/build the project is in the `/src` directory, 
+with the headers residing inside the `/inc` directory for most public modules.
+
+All other directories are for supporting the development cycle and are used for
+testitng the code base to ensure accuracy and quality. These are contained in
+the `tests` and `mocks` directories.
+
+Documentation that has been generated is inside the docs folder which contains
+the html output that can be browswed via your regular web browser.
+
+PDF genreation from the doumentaiton is also possible if enabled through the
+`Doxyfile` inside the projects root directory.
+
+The build directory contains the output and makefiles genrerated automatically
+when using CMake.
+
+This build directory also holds the bin files genreated along with the hex and
+elf files.
+
+## Build Requirements
+
+- AVR-GCC toolchain OR XC8 from microchip.
+- Make OR CMAKE
+- avrdude
+- A AVR programmer, usbasp for older chips and UPDI for newer ones.
+
+
+## Dev Requirements
+
+- ATtiny404 series micro-controller
+- AVR-GCC toolchain.
+- Cmake
+- cpputest(Unit testing harness.)
+- Doxygen(For documentation) 
+- Git(For version control)
+ 
+
+## Running Unit Tests
+
+To run the cppunit tests you can use the included shell script inside a bash
+shell.
+
+```sh
+echo "1" | ./otto.sh
+```
+
+The command runs the otto script which automates parts of the development cycle
+such as running and building tests, compiling hex files and flashing the code
+to a micro-controller using arvdude.
+
+
+## Roadmap
+
+Some stuff that still needs done.
+
+- [ ] Write Unit Tests for Serial Comunications.
+- [ ] Write Unit Tests for Timer/Counter (10Khz)
+- [ ]
