ERROR: Not enough RAM (YDATA)

[karl567]

I am trying to adapt your ready-to-use-example "FFT-Demo" for using it with dsPIC33EP512MU810.
But mikroPascal PRO for dsPIC (Version 5.8.1) reports an error: "Not enough RAM 'InputSamples'".

Please help me.

Kind regards,
Karl

Hello,

With dsPIC EP chips buffer array of ydata must be declared in far ram.
Current implementation of our FFT library is unable to work with data located in FAR RAM.

I have reported this to our developers and they will investigate this thoroughly.

Best regards.

Hi,

is there a chance for me to get a solution in near future? The FFT is essential in my code. I think it would be also intersting for many other. Thank you.

Best regards,
Karl

Hello,

Unfortunately at this moment I don't have precise information.
I could only suggest using dsPIC30 chip instead.

Best regards.

Hi, any new about this topic??
Fir Filtering is the core of my new code and I'm unable to declare variables in ydata space.
I'm using a dsPIC33EP512GM604 but everytime I declare a new variable in ydata space I get an OUT OF MEMORY error ....

Please help.

Regards

Stefano

Hi,

Unfortunately, there is no some new information regarding this issue.

You have "Not enough RAM" error message because you need to use far memory qualifier:

Code: Select all

far ydata unsigned InputSamples[NUM_OF_SAMPLES * 2]; 

but also in this case you will have error message because, current implementation of our FIR library is unable to work with data located in FAR RAM.
