Preparation
- After power on the module, please wait for around 10 seconds. The module will then send
hellovia UART and listen to incoming commands. - Each command should end with
\n. - UART means UART-A/rs232-A interface on mPCIe connector.
- UART configuration:
baudRate=115200, parity=none, dataBit=8, stopBit=1, no flow control
Command List

Get available I2S/TDM format | i2s_0,i2s_1,i2s_2,tdm_0,tdm_1,tdm_2,tdm_3,tdm_4 |
chNum_phyRx=8 |
Set number of I2S input channel (If the module does not support DSP, this command also sets the number of network output channel) | None. 1 |
chNum_phyTx=8 |
Set number of I2S output channel (If the module does not support DSP, this command also sets the number of network input channel) | None. 1 |
chNum_dspFromNet=0 |
Set number of network input channel (DSP Module Only) | None. 1 |
chNum_dspToNet=0 |
Set number of network output channel (DSP Module Only) | None. 1 |
sampleRate=48000 |
Set I2S sample rate | None. 1 |
fmt=tdm_2 |
Set I2S/TDM format | None. 1 |
inv_lrclk=0 |
Set I2S LRCLK polarity, =1 means inverted |
None.1 |
inv_bclk=0 |
Set I2S BCLK polarity inversion, =1 means inverted |
None. 1 |
Note
- When using
192ksample rate, please set I2S channel to2 in 2 out. Module currently does not support more channels under such sample rate.
