I am using AM355x for my project. I Need to calculate the ADC voltage from raw value. $cat /sys/bus/iio/devices/iio:device0/in_voltage2_raw 3360 How can i covert this raw value into voltage ? Currently I m using following formula to measure the voltage voltage = raw value...
And I tried using this calculation for converting voltage from ADC value and than over voltage divisor formula calculate input voltage to be measured, and it shows correct at the beginning of scale but as th...
The standard voltage is used to convert the value of AD to the voltage value required by the user. The calculation formula is as follows: Vref / (2^n-1) = Vresult / raw Note: Vref is the standard voltage n is the number of bits converted to AD Vresult is the collection voltage ...
1.3.3. Calculate the collected voltage¶ The standard voltage is used to convert the value of AD to the voltage value required by the user. The calculation formula is as follows: Vref/(2^n-1)=Vresult/raw Note: Vref is the standard voltage ...
The input voltage range of an ADC is determined by the reference voltage (VREF) applied to the ADC. A reference voltage can be either internal voltage or external voltage by applying a voltage on an external pin of the microcontroller. ...
(see Editor's note). Note that you must round off the result value to a whole number before converting to a hex-code value for better accuracy. The following sample calculation finds the hex-code value for a measured input-analog-voltage level of 1.6V when using a known microcontroller’s...
* Calculation formula: controller_clk = (`APLL` or `APB`) / (div_num + div_a / div_b + 1). * * @note: The clocks of the DAC digital controller use the ADC digital controller clock divider. */ typedef struct { bool use_apll; /*!<true: use APLL clock; false: use APB clo...

I could not decide what should be the ADC clock frequency. I am using 8 Mhz Fosc. So over the internet I have seen that minimum Tac must be 1.6 us. In datasheet for acquisition time calculation formula it seems like it does not depend on the clock frequency. But I believe that the ...
PWM frequency calculation: The PWM frequency needs to be decided upon based on the type of peripheral we want to actuate. For example, most servomotors operate at 50Hz, most BLDC motors support frequencies ranging from 5kHz up to 50kHz etc. This information needs to be known beforeha...
