BQ79606A-Q1: Battery Managment Studio , BQ79606A-Q1

Hallo Taylor, I'm happy to see you again. 

I understand already, what you written.I mean which Register i will read the temperature from it? can you write me the name of the register please? Where i can read the Temprature as a voltage , before the step of the ratiometric. Just want to read the volatge which represent the temperature 

BQ79606A-Q1

Many Thanks for your replay

Are they the right registers? where i can read the voltage, which represent the temperature? 

AUX_GPIO1_HU

AUX_GPIO1_MU

AUX_GPIO1_LU

as you see, initially i make a test for one BQ with one NTC sensor, and i get allowas the same result. when i try to read AUX_GPIO_HU/MU/LU and also  when i try to read AUX_GPIO1H/L

I'm waiting for your response 

As my understanding. I already did what written in 8.3.4.4.3 AUX GPIO Input Measurements

But why i read the same temperature. and also the voltage on the TSREF is zero not 2,5V?

Hi Taylor, 

thanks for your response 

I already did, as you see in the screenshot of the Battery Managment Studio and in screenshot of the code also

Do you have a a code example. the same code like that but also with temperature, one AUX-ADC is enough

I'm waiting for your response

Thank you for your response

I set the TSREF_EN  , and I can read with 2.5V with the Voltmeter, and the voltage drop on the sensor NTC changed with the temperatur, but i always read the same value from the register  AUX_GPIO1H.

I don't kow why? 

I'm waiting for your responce 

Hi Bishoy,

Do you have GPIO set to analog input correctly and AUX ADC turned on?

Regards,

Taylor

Hello Taylor, 

thank you for your response. 

i set the GPIO to analog input through the GPIO_ADC_CONF bit number B0; the GPIOCONF1 as you see in the screenshot

I also enabled the conversion of the GPIO for the AUX_ADC through the AUX_ADC_CTRL1 bin number B4 

Also, I enabled the TSREF in CONTROL2 bit number B4

But I always get the same result when I read the 2 registers of the Temperature. 

If you can write me the steps to read just one absolute value  Temperature from a GPIO1, I will be very thankful for you, I already read the Datasheet a lot. But always the same problem knowing that the communication is totally correct because it tested with the Battery Management Studio and it works very well  

I appreciate your time a lot
