Quantum Leaps

Hi Gene, A non-trivial example of applying QP is the "Fly 'n' Shoot" game used in Chapter 1 of the PSiCC2 book. This example is also explained in the video "Active Objects, Hierarchical State Machines, and Modeling in Practice". In that video I also lay out several architectural guidelines. But, generally, your objectives are: Avoid direct sharing of resources (e.g., I/O devices). Instead of sharing resources directly, encapsulate them inside dedicated AOs. The AOs that manage the resources become...

Hi Tvishy, I understand that your laptop cannot run Windows 11. In that situation, your alternative is to use VSCode on Linux together with the necessary extensions to cross‑compile for the embedded targets used in the course (TivaC LaunchPad or NUCLEO‑C031C6). Unfortunately, getting all of this working on Linux is not trivial. You would need to install and configure VSCode, the C/C++ extensions, the ARM toolchain, and likely OpenOCD or another debug server. This setup requires solid Linux skills...

Hi Julio, Yes — the standard QP/C and QP/C++ editions include support for both FreeRTOS and ThreadX. The SafeQP editions do not yet include ports to third‑party RTOS kernels. Regarding the standard QP frameworks: over the years they have been used extensively in medical devices developed under IEC 62304, including many Class C systems. However, Quantum Leaps was not directly involved in those certification efforts, so we did not own — and therefore could not provide — the certification artifacts...

Hi Glenn, Thanks again for following up — I’m glad the installation eventually succeeded. Ha, I didn't think I was on the bleeding edge of taking a new release. You actually weren’t the first to download 8.1.5. You were simply the first after the (overpriced) DigiCert code‑signing certificate had expired. The files were signed while the certificate was still valid, but Windows appears to validate the signature against the current subscription status rather than the status at the time of signing....
