Experiment: run the labTool on FreeRTOS:

I have it working on RTOS standard (single core). Goal is to run tasks on both cores later. That could be useful for designs like the [mention:cb8171f974c143a799c072d3490f534c:f7d226abd59f475c9d224a79e3f0ec07] .

Hello,

I am new to LabVIEW. When I open the driver example it only opens the front panel like the image below. How can I open the block editor?

this is experimental functionality, but doesn't impact the current API.

Little speed test:

It's a little loop that toggles a pin. It runs at approx 1.6 kHz on my setup. Loads of jitter - this is not deterministic. But it shows the simple command speed of this setup.

The time between two commands (an edge) is +- 340 µs

Your sample VI appears to only work with the latest labview version?

Generating a variable duty cycle output is now available in the development branch. Developed by [mention:b0bc65b9ecdc4307bd967592f00e340a:e9ed411860ed4f2ba0265705b8793d05] (pull request).
Example commands, set and get the duty cycle of a PWM output:

This is great work!

Have you ever tried running the Labview runtime engine on an arm board?

Looks cool, but I am not up to building one.
