CC2640R2F: ADC provides only fixed values

Sami Lakka76

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC1310

We are testing ADC in CC2640R2F with our own board, where we use 4x4mm version of the MCU. The analog input is in DIO_8 and we tested with adcsinglechannel example project which is provided with TI. In Launchpad the read routine is working perfectly. With our own board we are getting fixed values around 617-618 even though we are feeding the pin with fixed 900mV DC signal. When we drive the pin with signal generator we only get small changes with the values (delta around 100 values), although the signal amplitude above 1V. I read the pin configuration of DIO_8  PINCC26XX_getConfig(IOID_8) and compared it to pin config of Launchpad (IOID_24) and it shows the same configuration (i.e. bit 18 and 17 turned on). 

I first thought that the pull-up/down resistors could cause issues but they should be turned off, as the getConfig() shows. Is there some other configuration that might mess the reading or could this be related to crystal or input voltages to the MCU?

    Could you post all parts of the code that you have changed with regards to pin mapping?

    Of course,

    Below are the code files CC2640R2_LAUNCHXL.c and CC2640R2_LAUNCHXL.h.

    I could not see anything at first glance that gould explain this. I don't have a 4x4 easily available hence it's a bit difficult for me to test.

    Instead of removing a lot of defines etc, could you first do a very small change? Starting with the original boardfiles, set:

    #define CC2640R2_LAUNCHXL_DIO23_ANALOG IOID_8
    #define CC2640R2_LAUNCHXL_DIO24_ANALOG  PIN_UNASSIGNED

    .

    .

    .

    In addition everything else not used has to be set to PIN_UNASSIGNED since the device has fewer IOs. I assume that you have checked that the voltage you want to measure is actually present on DIO8.

    Hi,

    I used the original board files and made the defines as you suggested. However the behavior is still the same. We have two boards and we tested with both and get the same ADC values (start from about 520 and then drift to 618 in about 10 samples). The voltage is present in the DIO_8. There is a gain stage that feeds into the ADC pin and if we remove it and drive the pin directly with signal gen, we get little bit erratic behavior where the ADC does measure something but the signal swings detected by ADC are much smaller than they should be.

    Do you have a launchpad you can do the same measurement on? You result could indicate that the pin mapping is not the issue.

    Hi,

    I tested by rerouting the signal to Launchpads DIO_24 and Launchpad's 7x7mm is providing the correct values from ADC. This is bit baffling. I could try to drive the IOID_8 up and down to see if there is galvanic problem in 4x4mm processor. Quick question, should following code be able to do that? 

       GPIO_init();
   GPIO_setConfig(Board_DIO24 , GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);
   GPIO_write(Board_DIO24, 1);
   GPIO_write(Board_DIO24, 0);

    Hi,

    I tested the galvanic connection of the 4x4mm and I'm able to drive the IOID_8 to 1.8V and 0V by using PIN_SetOutputValue. So the problem cannot be a galvanic connection between the processor and its pads. This has to be a configuration issue but I'm now having difficult time to understand what could mess the ADC configuration so that it would always provide values of around 618 even if there is no signal (0V DC)?

    Ok, 

    Just to recap our different findings:

    1) With 4x4mm the ADC on IOID_8 does not respond to the voltage that is coming to the pin. We tested by grounding the pin and setting different DC and AC values. Even when the pin is grounded, the ADC values are around 618. Only when the values are high enough you can see some small movement in the ADC values but these require voltages around 1V p-p. 

    2) We changed the VDDR and VDD_RF voltages from 1.6V to 1.8V and the ADC values came up from 618 to about 660. This means that the ADC values are linearly correlated to VDDR and VDD_RF.

    3) The IOD_8 can be driven HIGH and LOW using PIN_SetOutputValue. Thus the pin and its channel should be working so the problem is related to ADC block inside the MCU. 

    4) When the signal is rerouted to Launchpad and the same code is run, the Launchpads 7x7mm processor is providing the correct ADC values. 

    5) We have tested with two identical boards with 4x4mm processors and see the same findings.

    I would think that this is related to ADC/Pin configuration but we haven't done any changes to those, except setting the change in defines as instructed at the top of this thread. Now changes has been made to compiler or linker and the code that we run is the example code adcsinglechannel. Due to space constriction we cannot use the 7x7mm processor in our product so we have to get the 4x4mm to work.

    Hi,

    I’m lifting this again as this issue is pretty urgent for us. Is there something in the ADC configuration which might cause the ADC values to be fixed?

    Since I don't have a 4x4 CC2640R2F board to test with, I did a test with CC1310 5x5 EM. Since the ADC and the ADC driver is same for both devices the test should be equivalent.

    I took the adcsinglechannel for the CC1310 launchpad and changed this to reflect the pin out on the EM/ SmartRF06 board. 

    - In the board file I set all pins that I don't use to PIN_UNASSIGNED. The analog pins I set as follows:

    /* Analog capable DIOs */
    #define CC1310_LAUNCHXL_DIO23_ANALOG IOID_7
    #define CC1310_LAUNCHXL_DIO24_ANALOG IOID_8
    #define CC1310_LAUNCHXL_DIO25_ANALOG IOID_9
    #define CC1310_LAUNCHXL_DIO26_ANALOG IOID_10
    #define CC1310_LAUNCHXL_DIO27_ANALOG IOID_11
    #define CC1310_LAUNCHXL_DIO28_ANALOG IOID_12
    #define CC1310_LAUNCHXL_DIO29_ANALOG IOID_13
    #define CC1310_LAUNCHXL_DIO30_ANALOG IOID_14

    DIO7 is routed out to R1.11 and I set this pin first to 0 V and then to 3.3 V and I measured the correct voltage in both cases. (I used the rest of the example as is, in other words DIO7 is used.)

    Are you able to use the example and just change the board file as little as possible? 

    If that still give the same result, I suspect a hardware error even though you are measuring the correct voltage on the pin. I can take a look at the schematic/ layout if you like to see if I see something.

    Hi,

    Thanks for this, we will test with this setup. Really weird problem though..

    I see that you rejected the suggested answer but with no detail why?

    Hi,

    This was my mistake. I tested with singlechannel project and used your PIN definitions for analog channels and it started to work on our test boards. Now I just have to figure out why it didn't work with the other project. If I discover the reason I'll post it here for future reference.
