The SPI waveform is from the oscilloscope probe. I mean the probe direct measure at pin RG8 for SDO and RG6 for SCK from dspic.
What do you mean by the lowest data rate? Is it the lower frequency for ad9833?
Do you mean the SPIEN is set in bit form after the line of PPREN setting?why?
Hi,
The previous post was referred.
After 2 weeks did this coding by referring some example and notes such as:
http://www.analog.com/media/en/technical-documentation/application-notes/AN-1070.pdf
What I understand is that the dspic30f6010A will only becomes the master to send the data to the...
HI,
I have change and put them in the int main (void function).
However the same error is still occurred.
Does it correct the way I'm writing the code for variable x?
Hi,
I need some help to guide or overcome the error in writing coding that I have using MPlab.
Actually, I want to use dspic30f6010A as SPI Master, Frame master to communicate with my programmable waveform generator, AD9833.
I would like to produce sinewaveform with 2MHz.
Before this, I'm...
Hi
Ok.thank you for replying.
Does it is possible if i want to concern only on the conductivity of the complex impedance ?
Also, it is possible to assume the system as the RC series circuit?
Hi,
Let say if I have an insulator pipe with the conductive liquid inside it.
Then,I plan to attach one pair of rectangular metal electrodes on the periphery of the insulator pipe wall.
By doing this, I can assuming that the system will have two coupling capacitors of C1 and C2.
It is due to...
Hi
This is only and the full code that i used.
I just want to produce the pulse with 20MHz at pin B1.
With this statement:
"Instead use a timer to create pulse that is much accurate method using which you can also get variations in high precision."
Can you suggest or guide which method i can...
Hi,
I want to generate continuous 20MHz pulse using function delay_us() in ccs.
I used PIC18F4580 and the crystal was 10MHz with PLL. So that, I can get the clock is 40MHz.
I have this code:
When I compile the code; there is no error. However when I burn into PIC and test using...
Hi,
I want to generate sinewaveform using AD9833 and trigger it by SPI mode from dsPIC30F6010A.
But, I'm confuse to connect the FSYNC pin from AD9833 to which pin in dsPIC30F6010A
The setting that I did was:
AD9833: DSPIC30F60101A:
FSYNC ----> SS2/RG9
SCLK ------> SCK2/RG6
SDATA...
Hi ,
1) I found only one ic RMS-to-DC converter for high freq purpose at element14 website. The ic is LTC1968IMS8 with gain bandwith product 15MHz.
Thus, i decided to try it. Or this ic is not enough good for 2MHz system?
2) The shape of 'received' signal should be similar that is sinusoidal...
I had post my thread regarding this rectifier before this as the link below:
https://www.edaboard.com/threads/342365/
Should I change into Lt1226 for example?
See the attachment...As what I got, i believed that te signal is still a sine waveform.
Does means that I can't apply the RMS-to-DC...
Hi Klaus,
My applications is actually for electrical tomography with 16 sensors.
I give the 10 Vp-p, with operating frequency is 2 MHz sinusoidal waveform at transmitter sensor by using PIC18F4580 to trigger the DDS module,AD9833 and amplify using signal generator circuit,LT1226.
Then, the...
Hi,
I have my system that consists of sinusoidal signal and I would like to use it for ADC part.
Thus, how can I convert the signal so that I can use it for ADC part?
What I know is by converting the sinusoidal into full wave rectifier or by using RMS-to-DC converter, is there any other...
I thought the gain is represent by the RL. The resistor value that we used.
So. as long as my GBP is large than the frequency that I use I think is can be used.
Or it is actually a different gain?
The current 2.5mA is taken by considering amplitude value of voltage source which is Vamp= 3.54 x...
