Hello
I have a problem with the QLC+ software.
In cooperation with the RaspberryPi 3B, on it the DMX interface is plugged in front of RaspberryPi USB (FT 245RL) from BiteWizard(NL).
Software: qlcplus_rasbain_buster_20190825
Connected to interface output -> to TS 7b input.
My test device (pairs of TS 7B scanners) cannot be controlled by it.
Nothing moves!
QLC+ I have set the output under Inputs/Outputs UART 1:ttyAMA0 with a hook.
Nothing works.
I made measurements with the ozsilloscope. At the output of the DMX_interface I have measured nothing.
Do I have to activate certain things?
Must be changed in Linux, although it is a rather new (.img) version.
On the other hand I read that the interface should be recognized automatically.
With me it is, I think, not recognized.
I can't get any further.
Please help me.
Thanks in advance.
Greetings
Uwe

Dear Massimo,
i have tested the QLC+ succesfully on WIN7 with FTDI-Adapter.
Now i will test the QLC+ on my Raspi4, but I´m not sure if it is possible für me to run the QLC on my Raspi4.
Is it possible to get a Trial-Version or a Test-Version of the QLC-image for Raspi. If i will bring it to run, i will change in a full version and for sure, i also will donate for you, but i´m not sure if it works.
Have i to use only the GPIOs of the Raspi for DMX-out or can i also use my FTDI-adapter?

Hello
The following commands are entered:
UART] If you have purchased a BitWizard DMX interface, please note that the hardware is configured for DMX input from the beginning. To switch it to output mode, you must add the following lines to the sudo nano /etc/init.d/qlcplus file, just before the line marked
QLCPLUS_OPTS="..:
echo 18 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio18/direction
echo 1 > /sys/class/gpio/gpio18/value
Note for Raspberry Pi 3: Also add the following to the config.txt file:
dtoverlay=pi3-disable-bt
Nothing has changed.
Thanks

Dear Uwe,
as I saw your name, i just thought you´re from Germany oder a german speaking country, is this right?
In this case, please, can you write me a private message because i have some questions of QLC+ on the raspi.
My account juste has been created a few days ago, that´s why i can´t write a message to you, but i´m sure i can answer to your message.....
