An advantage of software tasks over hardware tasks is that many tasks can be mapped to a single interrupt handler. Software tasks are also declared using the `task` attribute but the `binds` -argument must be omitted.

The example below showcases three software tasks that run at 2 different priorities. The three software tasks are mapped to 2 interrupts handlers. |
