LAUNCHXL-F28379D: Flash Memory Storage and Real-Time Processing

Tool/software:

Hi everyone,

I am currently working on the following tasks and would appreciate your guidance:

I have three sets of voltage and current data obtained from power system simulation software. These signals were sampled at 10 kHz for a 60 Hz system, resulting in approximately 52,000 points for each signal. The data have been processed to range between 0 and 4095. My goal is to store this data in flash memory, allowing it to be read and transferred in real-time to an MCU for operations such as filtering, downsampling, FFT computation, and protection decisions.

After exploring some discussions on this forum, I learned that the Flash API might be suitable for writing data to flash memory for later use during real-time operations. However, as I am new to this topic, I am encountering challenges. Specifically, I understand that the data must first be programmed into memory, but I have been unable to get the flash programming example in Code Composer Studio (CCS) to work.

Here are my questions:

  1. Is it feasible to achieve the workflow I’ve described?
  2. Does my proposed process make sense, or are there any steps I am missing?
  3. Are there any beginner-friendly guides or resources for using the Flash API?

Thank you in advance for your support.

Best regards,

    Hi,

    1. Yes this approach seems to be feasible.

    2. Please note that once you write to flash you if you need  to rewrite then you have to erase sector and then write.

    3. You can find flash api example code in C2000ware located at  <C2000ware install path\device_support\f2837xd\examples\dual\flash_programming>.  Refer http://www.ti.com/lit/pdf/spnu629 for details.

    Regards,
