Data logging using UART/SPI/ USB

breckjensen

Hello,

I am using the GUI instaspin F2806X.

My aim is to store every sample of current(Id, Iq), voltage(vd,vq), torque, rotor position,speed atleast 250 samples of each when my system operated at a switching frequency of 5KHz.

I have seen there are plots for current and torque which uses 50 or 100 samples of the logged data inside the microcontrollers. If I want to increase the number of sample to be logged, is there any way to extend memory?

or is there any way to read the data every switching period and store it in a file using GUI (when I tried this I am not able to do it every switching period as the transfer delay to gui is more).

Also if I use XDS560V2 , is ther any advantage that I could get for data logging?

"
I got a reply that I can use UART, SPI or USB for this purpose instead of JTAG. If so, is any body can guide me with some example for this?

Please Help.

Thanks !

I didn't find the right solution from the internet.
