+Repo for MATLAB-Code used on a RedPitaya device.
+Basic functionalities provided to access the RedPitaya via MQTT.
+A oscilloscope and a signalgenerator are implemented via MQTT.
+
+Structure:
+1. lib folder
+The "cosaMqttClient.py" contains MQTT-functions to send messages understood by a python library.
+And "mqtt_py_matlab.m" contains MQTT-functions used in MATLAB.
+
+    1. redpitaya folder:
+    Contains classes to store the structure of the oscilloscope signalgenerator.
+    The "OscilloscopeProperties" class stores all values needed to control the oscilloscope.
+
+    The "SigGenProperties" class stores general values to generate waveforms.
+    Each waveform has a own class to store specific info.
+    The general values are inherited by the "SigGenProperties" class
+
+2. Example folder:
+Contains "test_mqtt_py.m" to explain basic mqtt transmissions.
+
+
+    1. redpitaya folder:
+    Collection of redpitaya specific examples.
+    The "analog_read_slow_example.m" explaines the usage of the external pin header to analoge read by ADC.
+    The "Oscilloscope_example.m" show how the "OscilloscopeProperties" class is applied on a RedPitaya.
+    The "SignalGenerator_example.m" show how the "SigGenProperties" class is applied on a RedPitaya.
+
+    2. py_venv folder:
+    Virtual Python3 environment. Not commited to the main branch.
