Re: Codesys with touch screen

Hi Uday_1009,

Re: DA-Wandler

Hallo Thorsten, interessante Anwendung, habe ich so bisher noch nicht gesehen! Dein Code sieht gut aus und sollte so funktionieren. Falls du deinen DA-Wandler noch flexibler gestalten möchtest bietet sich der folgende Ansatz an: def dac_voltage(inputs: list): value = int("".join(str(i) for...

Re: Codesys with touch screen

Hi Uday_1009,

you can connect the touchscreen to your Revolution Pi and use any browser (eg. our default browser Epiphany ) to interact with the CODEDSYS webvisu.

Re: Boot after shutdown without power cycle

Hi Saar,

you could use a push button equiped with an opener contact for this. The opener contact must be placed between your PSU VCC and your RevPi VCC. With this solution the power is interrupted when you press the button and comes back when you release the button (works like a reset).

Re: Serielle Schnittstelle

Hallo Meph,

eine serielle Konsole gibt es beim RevPi nicht. Du kannst aber einen Monitor am HDMI Port (Gehäuseoberseite) anschließen und dort den Bootvorgang beobachten. Siehe hierzu auch: https://revolutionpi.de/tutorials/revpi-core/

Gruß Nicolai
