Project update 3 of 7
The recently updated PPS features increased RAM usage to nearly 50%. We’ve found about one-third of RAM is used by
const variables. Unlike a 32-bit MCU, the AVR MCU needs specific macros and functions to store and access constants from flash. We carefully implemented those while keeping the library platform-independent.
The result is a reduction of RAM usage from 1223 bytes (47%) to 736 bytes (28%).
The status logging feature is now fully functional. It logs the library status, source capabilities, and protocol packet name with timestamps in milliseconds for serial port traffic. The logging mechanism is designed to have minimal impact on PD timing.
