: Integrates a 4-channel 16-bit Audio ADC (94dB SNR) and a 3-channel 24-bit Audio DAC (105dB SNR). It natively supports two full-duplex I2S channels, S/PDIF, and HDMI ARC connectivity.
320KB SRAM and 16Mbit internal Flash for code and data storage.

A standard 2-wire debugging interface (similar to UART or dedicated JTAG-like tools provided in the SDK) is used to flash the firmware into the chip's internal flash memory.
Configuring pairing names, Bluetooth profiles (A2DP, AVRCP, HFP), and connection parameters. : Integrates a 4-channel 16-bit Audio ADC (94dB
Upon completing "Bp1048b2 Programming," students might be expected to:
Configure Audio Settings: Adjust equalizer settings, crossover frequencies, and gain stages. void mix_voices(void) for(int sample = 0; sample <
Debugging Bluetooth timing errors is difficult. Use a logic analyzer on the UART TX pin to output real-time debug logs. Next Steps for Your Project
