 INTERFACES 
 
 	- pin
-		- pin.h Updated with a header infromation "header" and missing function have benn added. 
-		- pin.h Is tagged wiht version 1.0 and will be concidered as the first stalbe implementation
-		- pin.h will also be used by other interfaces when they need to initiate alternate functions
+		- pin.h Is now only missing interrupt functions 
  	- USART
-		- we need to check what are the standart USART funtinalities and implement them all.
-		- usart.h the first implmentation will be made to make sure thte we have a working basis.
+		- usart.h Is wirking Great But there are many more functionalities to be added.
+		- usart.h Interrupt and DMA are the next steps
 
+	- deviceSetup	
+		- deviceSetup.h it's a copy of what ST has made but wit direct register acsess
+		- deviceSetup.h we need to test it with other configurations to see if it works as 
+			supposed or if the MCU is on it's defaul 8MHz congif. 
+		- setupInit(); funtion is called from bsl/csl/stm32f042/startup/startup_stm32f042x6.s and is called before the main(); 
 
 PROGRAMMING 
 	
 	- CPP
 		- CPP Classes are taking extreme ammount of code ! 5kB for one class
 		- Try to generate a CPP proect with cube to sse if we are missing some flags.  	 
+		- Huge difference i we use main.c or main.cpp as enrty point. somehow the first intoduction of classes are taking env. 5Kb
