Tool/software:
What is the correct way to read the AUX IN channel .
1. Power up the device.
2. Once the device is properly powered up, RESET the device registers by sending command 0x8500 on the SDI line.
3. Select the Manual AUX Selection
4. Send 0xE000 on SPI lines (Select the AUX IN Channel )
5. Send 0x0000FFFF on SPI lines ( AUX data on SDO line from 16th clock onwards).
AUX in - supply is 2 V.
but what I got in SPI line in 00 00 00 00.
it not clear in data sheet if you can help on this .
Hi Akhilian,
Is it only the AUX channel you are having issues with? Are you able to manually select the other inputs? Please refer to Figure 88 and replace MAN_CH_1 with the address for the AUX channel. Do let us know if that resolves your issue.
