where does my backend live?
-
New to Qt, obviously. I have a commercial license (Qt for Device Creation) but I haven't gotten a whole lot of help from Qt. I'm using the Toradex Verdin imx8mp SoM. Its taken me more than a month just to figure out how to build the qbsp and the image and make them talk to each other.
I have a really simple HMI (that's not true, I got nothing, but its coming!) that needs to communicate with a motor over UART0, PWM some fans, read a couple of I2C sensors, sample the ADC and go to sleep when not in use. Its all fairly simple code but coming from a bare metal Cortex M background doesn't help much. Could someone point me towards a simple example that continuously updates my graphics based on some kind of sensor?
The blocking serial example is helpful but I need something that runs in the background and updates the UI rather than purely event driven based on user input.

Then don't use Qt serial port module in blocking way.
See https://doc.qt.io/qt-5/qtserialport-creaderasync-example.html
Qt serial port implementation is asynchronous.
