+## Radioberry Configurations:
 
-	Two java applications are being under development:
+	Initialy i had the idea of using JAVA as then main programming language, 
+	but the lack of speed when reading and writing to the GPIO of the raspberry pi 
+	forced me to use the 'C' programming language.
+
+	Setting the SI570 at the right fequency is done using the I2C bus of the pi and a JAVA progam.
+
+	Three applications are being under development:
 
 	- HermesLite 
 	- Radio Berry
 		On the RPI a webserver (using websockets for spectrum and audio) including the ported WDSP lib
+	- Standalone transceiver
 
 
 ## HermesLite
 
-![RadioBerry](Gallery/Emulatie Hermes Lite.png)
+Using a SDR program via the OPENHPSDR protocol and a network connection.

 ## (Web) RadioBerry
 
 ![RadioBerry](Gallery/WebRadioBerry.png)
 
 Starting RadioBerry using the following command:  java -jar radioberry.jar 
 
+Internally using the WDSP library.
+
 Oeps.. in the WeServer class i hard coded an IP address ... for now modify and export the jar file...
 
 
 Open a modern browser and start the URL ; i have created an initial ssb.html! 
 
 For different modes an unique interface can be designed.
 
+Because of the performance problems i have to change from JAVA using an embedded JETTY server to C using mongoose as webserver.
+But the idea of making special pages for the different modes still stands!
+
+
+
+## Standalone transceiver
+
+Using a touch display and maybe some knobs....

+As DSP lib using the WDSP library.
