5.3.12Code Performance Analysis
A keyboard report processing is used to analyze the code performance. A typical keyboard report processing contains the following steps:
■The bridge receives the keyboard report packet and process the packet. This step takes 108 µs.
■MCU calls function handle_keyboard_report() to format USB packet and load this packet into the endpoint buffer. This function consumes 118 µs.
As a result, it takes 226 µs for the bridge to process a keyboard report.
