 # Hardrock-50 Remote Display
 
+The Hardrock-50 is a 50W power amplifier for amateur radio QRP transceivers. It has a display showing valuable information like the selected band, the SWR, power, temperature etc. Since I am using the HR50 in a remote station, I cannot directly access those information via the display.
 
+However, the HR50 offers serial communication via a USB port. This project tries to solve this problem with the help of a separate, wifi enabled hardware display. It consists of the following two components:
+
+* Heltec ESP32 board with display
+* a python flask application, which represents the communication via the serial interface in the form of an API
+
+
+This is how the display looks like in action:

+
+## Configuration
+
+Edit the following lines inside the Arduino sketch:
+
+```
+const char* ssid = "<ENTER_HERE_YOUR_WIFI_SSID>";
+const char* password = "<PASSWORD>";
+String api_url = "http://<ENTER_HERE_THE_IP_OF_YOUR API_SERVER>:5000/status";
+```
