void trace(const char *msg) // No UART here – just write to RAM int len = strlen(msg); memcpy(&trace_buf[trace_idx], msg, len); trace_idx = (trace_idx + len) % 1024;

: Supports FreeRTOS for multitasking and real-time operations.

Convert all biquad coefficients to Q1.31 format.

Maintaining a consistent coding style is essential for readability and maintainability. Here are some guidelines to follow:

Since there is no official "Arduino IDE" or high-level wrapper for this chip, "programming" the BP1048B2 involves communicating with it via using a protocol provided by the manufacturer.

Ensure that your error handling mechanisms are comprehensive and effective.
