Greg,
In computer '11' and '0x0B' will give you same value. '11' is with decimal. You can not get decimal '17' with writing '11', you can get it with '0x11'.
If there is no issue for the code, lets back to the original problem.
For schematic, the START pin is connected to GND and I always use START command to activate the ADC into continuous mode.
This problem occurs on both my prototype board and Ti's ADS131E08 demo board with the ARM MCU demo board.
I noticed that once the ADC part is in stuck, any reset command from MCU is not helpful and the only way is the cycling the power.
Any suggestion?
Is hardware RESET/ pin or PWDN\ pin can deal with this issue?
Thanks,
Ming
