serial communication with the tms320f28069

Hi Gautam,

No luck  , no answer from Trupi.

Any idea ?

Thanks

Hamid

Hi Gautam

I found my answer in the tread :

 e2e.ti.com/.../206792

Library located here:  C:\ti\controlSUITE\device_support\f2806x\v130\MWare\utils

Please I have one question:

I am trying to run the example : Example_2806xSci_FFDLB_Int    

I am using CCS ver 6.1   during compilation I have the error :

"C:\ti\controlSUITE\device_support\f2806x\v150\F2806x_headers\include\F2806x_Usb.h", line 1076: error:
identifier "Uint64" is undefined

but Uint64 is defined in f2806x_Device.h

#ifndef DSP28_DATA_TYPES
#define DSP28_DATA_TYPES
typedef int int16;
typedef long int32;
typedef long long int64;
typedef unsigned long long Uint64;
typedef float float32;
typedef long double float64;
#endif

Thanks for your help

Hamid

Hamid - Have you resolved the issue? 

It is possible a different copy of DSP28_DATA_TYPES is being pulled in from another file.

Thank you   Elizabeth   and Lori,

Yes by openning a new workspace  the problem is solved.

Please I need clarification on how the fifo interruption works :  I would like to have interruption every time the buffer is empty. if I use  do : SciaRegs.SCIFFTX.all=0xC022    is that mean I will have interruption when I have 2 chars in the fifo buffer ?  I know its explained in the manual but not clair for me.

any help will be appreciated.

__interrupt void sciaTxFifoIsr(void)

{
Uint16 i;

//

//  code

//

SciaRegs.SCIFFTX.bit.TXFFINTCLR=1; // Clear SCI Interrupt flag
PieCtrlRegs.PIEACK.all|=0x100; // Issue PIE ACK
}

void scia_fifo_init()
{
SciaRegs.SCICCR.all =0x0007; // 1 stop bit, No loopback
// No parity,8 char bits,
// async mode, idle-line protocol
SciaRegs.SCICTL1.all =0x0003; // enable TX, RX, internal SCICLK,
// Disable RX ERR, SLEEP, TXWAKE

//SciaRegs.SCICTL2.bit.TXINTENA =1;

SciaRegs.SCICTL2.bit.RXBKINTENA =1;
SciaRegs.SCIHBAUD = 0x0000;
SciaRegs.SCILBAUD = SCI_PRD;
SciaRegs.SCICCR.bit.LOOPBKENA =0; // Enable loop back
SciaRegs.SCIFFTX.all=0xC022;

SciaRegs.SCIFFRX.all=0x0022;

SciaRegs.SCIFFCT.all=0x00;

SciaRegs.SCICTL1.all =0x0023; // Relinquish SCI from Reset
SciaRegs.SCIFFTX.bit.TXFIFOXRESET=1;
SciaRegs.SCIFFRX.bit.RXFIFORESET=1;

}
