TMS320F28379D: Can't read the data from memory and store it in the file?

Kamran Awan

Hi all,

I am working with F28379D. Its working fine as far as the control part of my experiments is concerned but the problem I face is in 'reading the data from memory'.

So my system work on EPWM interrupts. With each interrupt it reads the sensors values and the values in the memory should be updated with every interrupt. I don't know how to read the memory with each interrupt and store the values in a file.

I have some queries:

1) where should the memory read function be? in the ISR or in the Main() function?

2) how to read the value of memory location with each interrupt and store it in the new row of an excel file?

If someone has done this before and has an experience, please help me with this?

Hi,

Are you using FatFS or some kind file system in the device? Or are referring to a file in your PC?

Hi Veena,

Thanks for your reply. I am trying to export the data to an excel file but it's not something that I'm stick to. The purpose is to save the data for analysis later.

So, you want to save the data from the device to an excel file in the PC, is that right? Using the debugger you can sump the memory content to a file. Is that what you are looking for?
