Hallo,
ich habe das Problem, dass ich mit HTerm 0.8.1 beta keine Daten von meinem Controller empfangen kann.
Folgendes Programm von ATMEL AVR32-UC3-SoftwareFramework-1.6.0 ist auf dem Controller installiert (Laut Beschreibung am Anfang des Programms, sollen empfangene Daten zurück gesendet werden):

* \section intro Introduction
* This is the documentation for the data structures, functions, variables,
* defines, enums, and typedefs for the USART software driver.\n It also comes
* bundled with an example. This example is a basic Hello-World example.\n
* Example's operating mode:
* -# A message is displayed on the PC terminal ("Hello, this is AT32UC3 saying hello! (press enter)")
* -# You may then type any character other than CR(Carriage Return) and it will
* be echoed back to the PC terminal.
* -# If you type a CR, "'CRLF'Goodbye." is echoed back to the PC terminal and
* the application ends.
*

Ich habe folgendes Board: http://alvidi.de/avr32_modul_bmb.html
Das Board ist mit einem USB-Adapter (Hersteller: ATEN Model: UC-232A) am PC angeschlossen. Das LED am Adapter blinkt während des Sendens.
Zum Senden und Empfangen habe ich am Board die PIN´s 232IN0 und 232OUT0 angeschlossen und GND_1.
Das Board wird mit 12 V betrieben. PIN´s GND_2 und 5-12V.
Der PIN 232IN0 hat in Warteposition -6,29 V und beim Senden mit HTerm -6,12 V.
Der PIN 232OUT0 hat die ganze Zeit -4,88 V.
Leider weiß ich nicht wie ich das Problem lösen soll und hoffe auf eure Unterstützung.
Vielen Dank.

Ich habe folgendes Board: http://alvidi.de/avr32_modul_bmb.html
Das Board ist mit einem USB-Adapter (Hersteller: ATEN Model: UC-232A) am PC angeschlossen. Das LED am Adapter blinkt während des Sendens.
Zum Senden und Empfangen habe ich am Board die PIN´s 232IN0 und 232OUT0 angeschlossen und GND_1.
Das Board wird mit 12 V betrieben. PIN´s GND_2 und 5-12V.
Der PIN 232IN0 hat in Warteposition -6,29 V und beim Senden mit HTerm -6,12 V.
Der PIN 232OUT0 hat die ganze Zeit -4,88 V.
Leider weiß ich nicht wie ich das Problem lösen soll und hoffe auf eure Unterstützung.
Vielen Dank.
