+# Coding Guide
+
+## ToDo's and Discussion
+* Rieter data type (ru8, ru16, ru32, ri8, ri16, ri32, rbool, ...)
+* Use Googles StyleGuide https://google.github.io/styleguide/cppguide.html?
+
+## Generell
+* Indentation `Instead of Tabulator use 4 Spaces`
+* Variables `Names are in CamelCase`
+* Queues `Only used in ther own modul`
+* Global variables / extern declaration `Avoid them - use getter/setter-functions` `(If it is really needed use include of its header instead of another extern declaration)`
+* Follow the rule `Code is like humor - if you have to explain it, it's bad`
+
+## Module
+* Name is a combination of its software layer which its from and the feature of it (TBD prefix "r")
+* Initialization-function is needed by every modul (empty or not) called modulnameInit
+* Every modul (c/cpp) has own (or more) h/hpp files with the same filename (more files use postfix)
+
+Standard: LayerFeature.c and LayerFeature.h
+
+Optional: LayerFeatureUsecase.h
+
+## Functions
+* Functions with return only has one return in the last row
+
+## Includes
+
+## Defines / Macros
+* Start with prefix D_
+* Only use UPPERCASE
+* Use brackets for the value
+* Global defines also have the modulname where they come from
+* Macros use M_ as prefix instead of D_
+* Avoid magic numbers in code and use defines instead
+
+```
+#define D_<MODULNAME_>FEATURE_NAME     (value)   //comment
+#define D_STACKSIZE_DEBUG              (0x200)   //bytes
+#define D_YARNHANDLE_TIMER_XYZ         (12)      //ms
+```
+
+## Enumerations
+* Enumtype start with prefix te followed by Modul which it comes from and the Name d
+* Enumerations start with e followed by Modul, Name (of enum) and _NAME (uppercase for constant name)
+* Set the first enumeration to zero, if possible
+
+```
+typedef enum{
+    eModulName_INIT = 0,
+    eModulName_START,
+    eModulName_END,
+
+    eModulName_NUM
+}teModulName;
+```
+
+## Structs
+* Name start with prefix ts followed by Modul which it comes from and the Name
+
+```
+typedef struct{
+    uint8_t	sFeatureName1;
+    int32_t sFeatureName2
+}tsModulName;
+
+tsModulName sName = {
+    .sFeatureName1 = 0;
+    .sFeatureName2 = -12;
+};
+```
+
+## If / Switch case
+* Curly brackets for every if/else/elseif-case
+* Constants on the left side at if/elseif to avoid "=" instead of "==" bugs
+* Always use default-case in switch
+
+```
+if(0x1337 == variable){
+    //code
+} else {
+    //code
+}
+
+if(0x1337 == variable){
+    //code
+}
+else{
+    ; //code
+}
+
+switch(variable){
+    case 0:
+        //code
+        break;
+    default:
+        //code or not
+        break;
+}
+```
