Mvp All Star Game 2012 Basketball Draft. Hi, I finally managed to test some DMX data transmission using QtSerialPort and threads (thanks to ) My simple app works fine on a FTDI DMX-USB adapter and now I am testing the same app on a Raspberry Pi with a UART DMX hat: The DMX protocol requires a custom rate of 250Kbps so I call setBaudRate(250000) before opening a QSerialPort. On the FTDI adapter (ttyUSB0) this works, while on the UART hat (ttyAMA0) it doesn't output anything and the kernel says: [ 90.322470] uart-pl011 dev:f1: WriterThread sets custom speed on ttyAMA0. This is deprecated. Kernel is: Linux raspberry-pi 3.18.11-v7+ #777 SMP PREEMPT Sat Apr 11 17:30:37 BST 2015 armv7l GNU/Linux Libc version is: 2.13-38+rpi2+deb7u8 Searched for the message with google and I found a couple of interesting discussions: Apparently, setting a clock divisor is not always the right way and I can confirm another software using pure C calls works fine with the UART hat that I have. This is how they do it: I tried to make a patch with that code into qserialport_unix.cpp but with no luck.
