CC2640R2F: Muxing ADC Vref to a pin

Part Number: CC2640R2F

Hi,

I would like to output the 1.48V ADC Vref to a pin as a reference for an amplifier stage. This was covered already here, but for the AUXIO7 pin only - can the signal be output to other pins or, more broadly, is there a description for the bit-values of the MUX4 register which controls this (it is not detailed in the TRM)?

Also, is there a way of performing this muxing from within the Sensor Controller using its bundled commands?

Thanks,

Jamie

  • The link to the post you refer to doesn't work so I link to it for completeness: 

    As you see the overrides are controlling the ADI_4_MUX register. The documentation for this register could be found here:

    If you scroll down to MUX4 you will see what you have to set the second to last override to to select a different DIO. I haven't tested this, try with the overrides provided in the original post first. 

  • That's great, many thanks for the quick reply. I have always used the TRM for register specifications but this one wasn't detailed - I wasn't aware that there was more complete information in the Driverlib documentation.

    I'll give this a go anyway but certainly looks like the solution.

    Best Regards,

    Jamie
