@tt12514 Change this crappy crystal or use ext reference (ocxo), put some cap on power line, y'll get a very better phase noise

NASA writes mission-critical flight software in C.
And the rules are absolutely INSANE.

> No recursion. Ever.
> Every loop must have a provable upper bound.
> No dynamic memory allocation after initialization.
> Max ~60 lines per function.
> Minimum 2 assertions per function.
> Every return value must be checked.
> Zero compiler warnings allowed.
> Daily static analysis. Zero warnings there too.
> No function pointers.
> Restricted pointer dereferencing.

This is how they write code at NASA / JPL for mission-critical systems.

@BERNHARDMarcel @Projet_BTRNC On attend que la base soit remontée depuis bientôt 1an, en attendant les logs pourrissent dans l'appli :😀

On this day in 1991, my photopolarimeter subsystem (PPS) was turned off due to degraded performance, saving 2.4 W of power.
