TLV320DAC32: TLV320DAC32 GUI

Hi Hasebe-san,

Unfortunately the TLV320DAC32 GUI shows some issues with OS compatibility, this GUI was developed some time ago. Although the EVM and USB communication works, one possible workaround is to use a different device GUI to perform I2C control through command-line interface.
TLV320DAC3203 GUI can be used as I2C control. You can use scripts like the following to control the TLV320DAC32:

Hello Ivan-san,

Thank you for your reply.

Thanks to you, I could to confirm the operation using the GUI of DAC3203EVM - KCS.
However, my customers said they want to make 4ch independent in Single-End.
So we changed and confirmed the single-end scripts you received from 4ch independently as shown below.

w 30 0E 80 # AC-coupled driver
w 30 25 E0 # LDAC & RDAC power up, HPLCOM independent output
w 30 26 10 # HPRCOM independent output
w 30 28 02 # soft-stepping disabled
w 30 2B 00 # LDAC unmute, gain = 0dB
w 30 2C 00 # RDAC unmute, gain = 0dB
w 30 2F 80 # LDAC routed to HPLOUT
w 30 33 0D # HPLOUT unmute, fully powered up, 0dB
w 30 36 80 # LDAC routed to HPLCOM
w 30 3A 0D # HPLCOM unmuted, fully powered up
w 30 40 80 # RDAC routed to HPROUT
w 30 41 0D # HPROUT unmute, fully powered up, 0dB
w 30 47 80 # RDAC routed to HPRCOM
w 30 48 0D # HPRCOM unmuted, fully powered up
w 30 65 01 # DAC_CLKIN = CLKDIV_OUT (not using PLL)

Then HPLOUT, HPROUT, HPLCOM could check the output but HPRCOM will not be output.
Is there a way to output Single-End from HPRCOM?
Can the DAC 32 output 4-channel Single-End?

Please let me know to reply above questions.
