Updated MIL-STD-1553 avionics databus application programming interface (API) software introduced by Holt

Oct. 2, 2023
HPL API supports all Holt's MIL-STD-1553 terminals to provide a layer of abstraction and enable software portability across platforms and processors.

ALISO VIEJO, Calif. – Holt Integrated Circuits in Aliso Viejo, Calif., is updating the company's MIL-STD-1553 avionics integrated terminal application programming interface (API).

The Holt Portable Library (HPL) API now supports all Holt's MIL-STD-1553 terminal devices to provide a layer of abstraction using standardized functions, and enable software portability for all Holt devices across several different platforms and processors.

The MIL-STD-1553 avionics interface HPL release is thread-safe and re-entrant, ensuring that several threads can operate on the same code without errors. A new RT-MT Stack Assist Mode monitor feature enables more efficient handling of interrupts.
