Hallo,
Hier mal ein Code für einen Spannungssensor mit einem Attiny85.
Da dieser keinen UART hat, und die Bascom softserial nur 8bit beherscht, mit eigenbaubasteluart für 9o2 :-)
Benötigt wird nur ein Attiny 85 und ein Festspannungsregler + Spannungsteiler.
Ausgabe der Spannung als EX Telemetrie und als Text Telemetrie.
Es ist auch kein Quarz notwendig. Der Sensor ist kleiner als ein 50cent stück
