I read the 4.10.0 User Manual on CanvasWidgetRenderer. I was unsure what it means by "CanvasWidget will not allocate memory dynamically, but will use memory from the buffer kept in CanvasWidget -Renderer."I see the commented line in main.cpp://static...

What's the difference between putting code in:MyScreenViewBase::MyScreenViewBase(){}vsvoid MyScreenViewBase::setupScreen(){}

I think I've caused some problem in the way I'm coding this interrupt. For a second I thought it was a pipeline re-entry problem like Clive-Two-Zero described in a different thread, but adding a volatile variable and incrementing it, didn't seem to w...

Thank you for the suggestion. I'll try it out. I tried adapting the USBX from the example above, but it keeps crashing at: dcd -> ux_slave_dcd_function(dcd, UX_DCD_TASKS_RUN, UX_NULL); In ux_device_stack_tasks_run.c line 87 of version 6.1.10

Hello Diane, Are there examples for standalone CDC ACM? Thank you,Du

On the L4R9I disco board, the MFX controlled the touch interrupt and if I didn't disable it, my screen would look pixelated when I tried to initialize a different screen. You might be onto something.I wonder if you could generate a simpler lcd output...

What's some of the other differences between the custom and eval board? It's possible the code is looking for something else and if it's not there, it doesn't initialize the LCD correctly...

It wasn't anything impressive.Instead of creating individual items for each letter and symbols, I made everything into an image and created a TextureMapper image and rotate it as if it was a dial. By spacing the letters and symbols at a fixed radian,...
