Migrating application from 8051 MCU to TMS320f28034 MCU

Hi Bandi,

Nope, there's no application note for the above migration. Btw controlSuite has good example codes to kickstart your project.
Simply download the same and let us know if you face any issues.

Hi Gautam,

Thanks for the reply.

I will go through the controlsuite.Actually i have gone though some examples..But i couldn't get how to handle things like interrupt handling and all..how it differs between those two processors.

And one more thing, it would be of great help if i get some example code of different drivers like SPI, UART..i may have to write new drivers..because in old processor it is done through memory mapping concept.Now they are planning to update it through some drivers.

I am new to embedded software.

Varun, you can find all the drivers for your device here: C:\ti\controlSUITE\device_support\f2803x\v130\DSP2803x_examples_ccsv5

Secondly, for handling interrupts refer "System Control and Interrupts" User Guide.
www.ti.com/.../technicaldocuments

Thank You Gautam..I will go through the documents.

Great! Let us know if you need any further help.

Goodluck & Regards,

Hi Gautam,

  I was going through the example for SPI driver present in C:\ti\controlSUITE\device_support\f2803x\v130\DSP2803x_examples_ccsv5\spi_loopback.

 I got some doubts.

For the below snippet of code:

SpiaRegs.SPICCR.all =0x000F;                 // Reset on, rising edge, 16-bit char bits
    SpiaRegs.SPICTL.all =0x0006;                 // Enable master mode, normal phase,
                                                 // enable talk, and SPI int disabled.
    SpiaRegs.SPIBRR =0x007F;
    SpiaRegs.SPICCR.all =0x009F;                 // Relinquish SPI from Reset

void spi_fifo_init()
{
// Initialize SPI FIFO registers
    SpiaRegs.SPIFFTX.all=0xE040;
    SpiaRegs.SPIFFRX.all=0x2044;
    SpiaRegs.SPIFFCT.all=0x0;
}

There is no explanation regarding how the value is being set for each structure or Union members.

I am finding it difficult to understand without proper comments.

Before referring the examples you need to go through the User Guide for SPI peripheral. So please read the document before going through the code as you'll understand nothing!

Hi Gautam,

 I went through the SPI Doc. I Saw the example code too.I am able to understand the code atleast to some extent now..I have a doubt.

Which is the best method to follow??Interrupt based or FIFO method ??

Varun, this is a very common question :)

If you ask me.... it depends on the 'application requirement'.

Hmm..Thanks :)
