This Chapter summaizes all of the resulting Workflow that has been developed during this Bachelor Thesis Work.
|

Mainly the Firmware Changes compared to the state at wich it was left off after the previously taken Internship \cite{

% TODO: insert ubib ref to Internship report
|
||||
}
|
||||
|
||||
\section{Firmware}
|
||||
|
||||
The PowerIt Firmware was updated to allow for the Calibration Procedure (described in \ref{calib}) and the Rgulation of its 1.8V output. That resulted in a new Version of the I2C Protocol between the Monitoring System and PowerIts.
|
||||
|
||||
\subsection{PI2CProto v2}
|
||||
The new Commmunication protocoll is based on the old one, and while the from the Host send Commands are compatible with version 1 the returned Message is not.
|
||||
And just like in the old Version a Master can send a message to the PowerIt with the in the \verb|command_t| struct described structure:
|
||||
|
||||
\begin{mintylst}{cpp}
|
||||
pi2c::command_t tosend { <crc>, 2, <CMD>, <optional_data0>, <optional_data1> };
|
||||
\end{mintylst}
|
||||
|
||||
Here the \verb|<CMD>| can be \verb|CMD_SET| for setting a value in the corresponding table (fig. \ref{registerbuffer}), using \verb|<optional_data0>| as address and \verb|<optional_data1>| as value.
|
||||
|
||||
Reading a number of bytes from the table can be accomplished with \verb|CMD_READ|, giving the address to start and number of bytes in that order.
|
||||
|
||||
While reading the complete Table is done with the \verb|CMD_READALL| command.
|
||||
|
||||
THe \verb|<crc>| byte is the CRC8 value of all following bytes inside \verb|command_t|
|
||||
|
||||
\subsection{I2C mapped Register-Table}
|
||||
When sending or reading values to or from the PowerIt, the address requireed is one of the 152 bytes documented in this table.
|
||||
\input{./tabs/registerbuffer}
|
||||
|
||||
\section{Calibration}
|
||||
\section{Calibration\label{calib}}
|
||||
|
||||
One of the goals of this Bachelor Thesis is to provide anyone required to calibrate a PowerIt Board with a comprehensive guide of, and inside into this process.
|
||||
|
||||
\subsection{Calibration-Table}
|
||||
|
||||
Of important note is that al calibration values of each PowerIt can be mapped via the naming and uuid scheme provided either by the corresponding stickers or the STM32-Chips internal uuid (accessible through address \verb|0x8c|, see figure \ref{registerbuffer}).
|
||||
There now also exists a global calibration Database, which will be loaded by the system on startup.
|
||||
|
||||
An example entry for each PowerIt entry looks like figure \ref{pitdb-example}
|
||||
|
||||
\begin{figure}[H]

||||

\subsection{How to calibrate a PowerIt Board}
|

|

The Calibration process is based on the PItSTOP Python scripts\footnote{

\subsubsection{Setting up the Test Environment}
|
||||
The simplest way to setup your environment consists of cloning the PItSTOP Project onto your Client:
|
||||
\begin{mintylst}{bash}
|
||||
|
||||
$ git clone https://url.to.pitstop
|
||||

then substituting the \verb|rsync| target:
