# FG004_A(Low Power Mode)
|
|
|
|
## Description
|
|
|
|
This embedded firmware is the testing mode for the triac software.
|
|
|
|
It causes the attiny404 to generate pulses continuously, which are delayed
|
|
by a value configured in the `config.h` file.
|
|
|
|
The timing is done after the PZC(positive zero crossing) of the AC input
|
|
waveform.
|
|
|
|
### Micro Controller Pins

## Project Layout
|
|
|
|
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
|
|
