ADAU1452_DSP Development Board and Learning Board ST2F103C8T6 AD1938_CODEC /CS42448 De Board

The new DSP board is equipped with MCU_ST2F103C8T6AD1938_CODEC board adds a single chip microcomputer to do soft control, can set the sampling rate and audio interface type.On-board routines provide input and output IIS/SPDIF (Fiber off/coaxial selection) interfaces (single ADAU1450-DSP board does not support SPDIF);1. For ADAU1452 series routines, the configuration page can freely choose the communication mode ( or I2C) between SIGMASTUDIO and the target board. The addre is 0x1 ADR0, and the I2C addre is: I2C 0x16 (118), E2Prom are 0x1 ADR0, do not need to change.2, USBi and target board (ADAU1452dsp board) link mode definition: communication mode: 1/3/5/7/9(CLK/CS/MISO/MOSI/GND) at the USBi end of the emulator corresponds to 5/4/3/2/1 of the target board (ADAU1452dsp board) CN2 respectively. Just in order.I2C communication mode: 2/4/6 (GND/SCL/SDA) on the USBi end of the emulator corresponds to 1/5/3 of CN2 on the target board (ADAU1452dsp board) respectively.3, the SIP1 on the target board as a s-starting jumper, in fact, basically usele, there is no need to cancel the s-starting, so you can throw away the jumper cap, try not to plug to the 12 end.4. The factory test routine is: ADAU1452 electrical subroutine 192tdm.dspproj This file, the matching AD1938 default 192K/TDM audio nsmiion, 4 s into 8 s out, if you need to change the sampling rate and audio interface, you can refer to the AD1938 board jumper description, otherwise the sound will not be normal.5, beginners recommend matching CS42448 CODEC de, support 6 s into 8 s output, there is a separate routine matching, factory routine 1452_cs42448_192.dspproj this file, in addition to higher indicators, and the line is concise, high stability, 48-192 sampling rate, No need to switch configurations, just focus on debuing the DSP.The factory setting is 192K_TDM format,OUT3/OUT4 is a sight-through interface, and OUT1/OUT2 is a stereo 2-frequency division mode output interface.S1 key input selection; Blinking blue indicates the SPDIF input, and blinking red indicates the IN2 og input. Green for IN1 emulation.S2 on preset EQ switch, a total of 10 EQ presets.S3 key super ba switch, useful in the electronic subwoofer , open by default;The three-color LED displays the input and the working status fing respectively;ST2 single chip microcomputer is reserved on the board, and the DSP can be controlled by single chip microcomputer, leaving USB/uart/ port, which can also be used as a single chip microcomputer development board.Potentiometer ADC acquisition to do volume control, LED driver example...
