Hi
I want write a byte in internal Flash of pic32mx microcontroller.i have tried sample code.But i cant able to read the exact data .. Anyone help me on that...
Sol 3 . use external HW to convert rms to dc and measure converted dc voltage through adc and calculate peak.(I cant use this solution ).......
Sol 4: In my project the freq will vary upto 1khz from 50hz.
I need to write software code for calculate peak + and Peak - from sine wave
Re: Frequency Measurement for AC Voltage
Ya i need ADC values to calculate those peak+ and Peak - @ Klaus.
Hi i dont know how many samples is needed ,because in my project frequency will vary from 50 hz to max 1khz. In this case how to measure the frequency in software .
for 5o Hz ,i am...
Re: Frequency Measurement for AC Voltage
Hi
How to do with samples tel me if anybody knows... ? Howmany samples i have to take ?
if any ADC code with frequency pls share forr pic32 microcontroller ?
Frequency Measurement for AC Voltage
Hi
I am using PIC32MX795F512l ,with 10bit ADC code.Using ADC , measuring DC as well as AC voltage in my project .
Now i want to calculate frequency for AC voltage . Anyone help me how to measure the frequency in pic32 with xc32 compiler... I am newone to...
Hi
I am using PI32MX795f512l .. I want to integrate flowcontrol in my uart communication .. As of now i am using only TX and RX pins for data transmit and receive ...
In Continous transmission ,in bluetooth module i am getting overwritten buffer...Pls Help me to come out of this.. I am new...
Hi
do you want to identify the channel sampled after adc interrupt, right?
Yess
tempsensor is ADC channel 1 and pot is channel2 ,i can able to read the value in both the channels ...My question is
if i am using the tempsensor ,then i have to set the variable channel =...
Hi i am trying to read ADC voltage from tw0 channels AN4 and AN3.... Values are updating correctly... I want to detect which channel is using ... Can anyone help me?
Here is My code for pic32Mx795f512l with XC32 Compiler, if am using tempsensor i have to assign channel 1 in variable otherwise...
Yes sir, i know i have to take so much samples for 20ms or 10ms time interval. the problem is how to take that samples with zero cross voltage over AC voltage in my c code... After taking that samples only i need to find peak+ and peak- voltage and RMS calculation .
Hi
I am using AC input of 50Hz .No DC Component.
I have Pic32mx795f512l microcontroller for ADC voltage sampling of AC input using ReadADC() function .From that i need to take samples at each 10ms of time interval and find peak voltage and RMS voltage.
Hi
I am using PIC32MX795f512l .I am new to this.. Anyone help me to find rms voltage and peak voltage for AC voltage as input for ADC
I am in urgent to close this ..
