    Hi, How are you converting the hex values to voltage? Please refer to the formula on page 524 and table 9.4 in TPS65950 TRM. If this doesn't help then let me know. Regards, Gandhar.

    before I set madcon to 1, I set GPBR1 to 0x90. this had no effect on the results registers. I had looked at this before and the documentation says that is the default setting so that is why I didn't set that registers before. But it did not seem to do anything. so the CTRL_SW1 register is continuously...

    Should I only have to set the channel bit in SW1SELECT_LSB register one time or each time before I start another conversion. I am doing the process described above once a minute. If I want to performa conversion once every second do I need to set the SW bit in the CTRL_SW1 register every time I...

    I am selecting CH2 in SW1SELECT_LSB, the SW1SELECT_MSB is for channels CH8-CH15. I am only working with CH2. I have read section 9.4.3.2 and am doing thoughs steps. I did not setup any interrupts, so INT1 would not interrupt, correct? In the section you mentioned number 8 says: "8. If the...

    The values of VINTANA1_DEV_GRP , VINTANA2_DEV_GRP and VINTDIG_DEV_GRP belongs to P1 and P2 Device groups and the state is active.

    my last response did not seem complete. for the VINTANA1,VINTANA2 and the VINTDIG, the GRP registers were set to EE which is active I beleive.

    I can read the adc results registers. It was the clocks not being setup correctly. When I origonally wrote to the GPRI register I had the wrong I2C Address group, I thought it was in the same group as the adc stuff. So when I changed that and it actually wrote a 90 to the register I started getting data...

    I am attempting to use the Monitoring ADC functionality and am having problems. We are using ADCIN2 and there is a correct voltage being applied to the adcin2 pin. For the MADC conversion process I am attempting to use the Software conversion request SW1. We have the startadc pin tied low, since we are...

    Hi I am using tps65930 madc to do analog to digital conversion on ADCIN2 input with and using SW1at host (AM3715) to control the MADC operation. I am using channel 2 for my conversion. I programmed the MADC registers as below: TWL4030_MADC_CTRL1_OFFSET:reg_val:0x0 TWL4030_MADC_IMR1_OFFSET:reg_val...
