Hi tao,
 
When I said that there is an error in my earlier post, it is because the Frequency bin=Sampling frequency /N. Does not really tally.  It approximates to be correct but if you do the maths, it does not.
 
I read thru some of your posts.  I personally feel that it is important to realise that fftcomplex uses fractcomplex which I had previously mentioned to you.
 
Do read up on fractional arithmetic.
 
But I personally feel that the limitation on samples (RAM ) storage on the dspic 4011 which I have been using is an impediant to to me.

Is your FFT prgram rigth now?The signal data type is int,like"0x0000, 0x4B3C, 0x79BC",and sin, cos too

It would be good if someone could update the file description on the web to match the file being downloaded. For example, the description "CE114-Timer 1 used as a Real-time clock", the associated file downloaded would be CE114_UART_loopback.zip. I've got to scan through the whole set of files in order to get to the right code example. Thanx.

i m working on under water vehicle
i have six motors and i have to drive it indipendently through pwm
is it possible to get indipendent 8 pwm from dspic 30f6010 ?
bcz  i have to drive thoes motors at diffrent speed

Best that you go for the 30F6014a which has eight independant pwm. I drive bipolar stepper motors with that configuration. You can load eight independant dutycycle registers with a value specific to that dutycycle that you wand on that output pin. That you can not do with the 6010. If you'd like more info I can give it to you.

Errata! I spoke too soon! You can use the simple pwm in the 6010, 8 dutycycle registers! It's the same then as the 6014 simple pwm, using the output compare pins on PORTD,0-7

thank you guys for the great help....this is web is the best Smile
hello Pate
how are you ?
i'm new on using PICs, and need some help please !!
i'm doing a project just like your one on ROVs but i'm going to use onely 4 motors... could you tell me how you are going to drive the motors with the PIC you chossed,i mean are you going to use DC/DC converter or... and how did you chosse this PIC.
thank you so much and i hope that your project is going well .

Linker Errors 2007/04/26 05:07:43 (permalink)
0
I tried to use the code examples given here as template for my code. I had used my variables in the code, correctly defined using C30 guidelines. But while compiling the code I get lots of linker errors which are otherwise absent in the original example code. The error lines contain the variable names that I'd used in my code. I tried editing the linker script manually using the help available in MPLAB, but the errors persist.

Pealse help me on how to create custom linker files, or if there is any utility to create linker files according to the code. Being a beginner, I haven't tried coding in assembly. I use v3.00 student edition of C30 and MPLAB v7.52. Processor is dsPIC4013.

hello,
first of all thankyou very much for putting the code examples on the web; very helpful indeed....:)
 
i have downloaded and am trying to use the example CE001 ADC file, but the explanatory pdf file attached is corrupted, (i think, i've downloaded it 3 times and i cant ever open it)........is there somewhere else i can get the file, or if not is there any way you (or someone) could re-post it....?
 
thanks again,
Larry

Hi KANNADIGA,
 
I join JBLACKBURN requesting more assembler examples for dsPIC. I prefer assembler for programming an embedded controller because a full control of the chip resources can be achieved.
 
Regards
