 Factory direct sales, high cost-effective hot selling products. Welcome to place orders for quality assurance.

It is recommended to purchase our emulation burner at the same time for development (USBI with 288 shell), and the package purchase will be more favorable. Materials include schematics and routines sent via email.

Due to the recent chip shortage, MCU_STM32F103C8T6 does not have a patch on the actual shipping board. The MCU itself has no program and can still work normally without a board. The AD1938_CODEC decoding board adds a microcontroller for soft control, which can set the sampling rate and audio interface type.

The on-board routine provides input and output IIS/SPDIF (off fiber/coaxial selection) interface (single ADAU1450-DSP board does not support SPDIF);

1. For the ADAU1452 series routines, the configuration page can freely select the communication method (SPI or I2C) between SIGMASTUDIO and the target board. The SPI mode address is: SPI 0x1 ADR0, the I2C address is: I2C 0x16 (118), and E2Prom is SPI 0x1 ADR0, no need to change.

2. Definition of the link method between USBi and the target board (ADAU1452dsp board):

SPI communication method: USBi end 1/3/5/7/9 (CLK/CS/MISO/MOSI/GND) of the emulator respectively correspond to 5/4/3/2/1 of the target board (ADAU1452dsp board) CN2. Just follow Arrange in order.

I2C communication method: USBi terminal 2/4/6 (GND/SCL/SDA) of the emulator correspond to 1/5/3 of CN2 of the target board (ADAU1452dsp board) respectively.

3. SIP1 on the target board is used as an auto-start jumper, which is actually basically useless. There is no need to cancel auto-start, so you can throw away the jumper cap and try not to plug it into terminal 12.

4. The factory test routine is: ADAU1452 electrical splitting routine 192tdm.dspproj file, the matching AD1938 defaults to 192K/TDM audio transmission, 4 channels in and 8 channels out. If you need to change the sampling rate and audio interface mode, you can refer to the AD1938 board Note about jumpers, otherwise the sound will not be normal.

5. Beginners are recommended to use the CODEC decoding of CS42448, which supports 6 channels into 8 channels for output. It has a separate routine. The factory routine is the file 1452_cs42448_192.dspproj. In addition to higher indicators, the circuit is simple and stable, 48 -192 sampling rate takes all, no need to switch configurations, just concentrate on debugging DSP.

The factory setting is 192K_TDM format, OUT3/OUT4 are straight-through interfaces, and OUT1/OUT2 are stereo 2-way mode output interfaces.

S1 button input selection; the blue light flashes for SPDIF input, the red light indicates IN2 analog input. The green light indicates IN1 analog input.

S2 button preset EQ switching, a total of 10 EQ presets.

The S3 button super bass switch is useful in the electronic crossover subwoofer channel and is turned on by default;

The three-color LED flashes to display the input channel and working status respectively;

The STM32 microcontroller is reserved on the board. You can choose to use the microcontroller to control the DSP, leaving USB/uart/spi ports. It can also be used as a microcontroller development board.

Potentiometer ADC acquisition for volume control, LED driver example.

CS42448  Chip Introduction

108 dB 192 kHz 6-input, 8-output multi-channel codec

The CS42448 is a highly integrated audio codec designed to simplify the design of home theater and car audio systems. Audio products provide advanced multi-channel surround sound performance. The CS42448 supports the addition of up to eight single-ended or six differential audio input sources, and up to eight single-ended or differential output sources. Highly integrated, multiple audio channels can be passed to the DSP chip for audio processing without the need for external analog-to-digital (A/D) converters. The auxiliary serial input is available for two additional PCM (Pulse Code Modulation) data channels. The inputs are more powerful, enabling audio/video (A/V) receivers that can receive audio from multiple sources. The CS42448 eliminates clicks and pops caused by power switching. This IC is ideal for audio applications requiring wide dynamic range, negligible distortion and low noise.

ADAU1452  Chip Introduction

Analog Devices' ADAU1452 is an automotive-grade SigmaDSP audio processor with fully programmable enhanced sound processing. The 1.2V 32-bit SigmaDSP processing core operates at a frequency of 294.912MHz and a sampling rate of 48kHz per time, exceeding 6144 SIMD instructions. Mainly used in automotive audio processing, navigation systems, rear entertainment systems, DSP amplifiers, commercial and professional audio processing.

AD1938  Chip Introduction

The AD1938 is a high-performance, single-chip codec with four built-in input analog-to-digital converters (ADCs) and eight single-ended output digital-to-analog converters (DACs), using Analog Devices' multi-bit sigma-delta (Σ- Δ) Patent architecture. It has an SPI port through which the microcontroller can adjust the volume and many other parameters.
