: I need to implement interfaces to RS232, RS422, and 1553B buses (in Ada).
Device drivers are heavily dependent on:
- The hardware device being used (register structures and automated
capabilities vary greatly)
- The hardware environment (influences decision on polled vs.
interrupt driven)
- The protocol (little variation for RS232/422, but varies greatly
for 1553B (e.g., various schemes for single BC, multiple BCs)
- Other nuances
One set of software cannot be reused without knowing many of these
details. Even with a simple RS-232 interface I've had to rewrite
completely when going from a Motorola to an Intel device.
Perhaps you can specify more so that we can think about helping...
