Keyur,
Which kind of trigger do you plan to use? Internal or external?
I will search and see if we have an example ready to be shared.
internal trigger from NHET1 pin 14.
NHET1 pin 14 would trigger MibSPI1 and MibSPI1 should flashes LED whenever it receive signal.
Keyur,
I've created a basic project using Halcogen to demonstrate the functionality of MIBSPI with an hardware trigger.
As per your request, NHET1_14 is used as trigger for MIBSPI1. The trigger will be active on a rising edge of NHET1_14.
MIBSPI1 uses transfer group 0, with 8 16bits buffers. On transmission, using Format 0, CS_0 will be active.
The NHET1 is generating 2 PWM at 1Hz, on pin_0 visible via an LED on the board and pin_14 (MIBSPI Trigger)
The main application is defined as:
void main(void)
{
/* USER CODE BEGIN (3) */
uint16 trans_data[8]= {0x1111,
0x2222,
0x3333,
0x4444,
0x5555,
0x6666,
0x7777,
0x8888
};
hetInit();
mibspiInit();
while(1)
{
mibspiSetData(mibspiREG1,0,trans_data);
mibspiTransfer(mibspiREG1,0);
while(mibspiIsTransferComplete(mibspiREG1,0)==FALSE);
}
/* USER CODE END */
}
An array of 16bit words is defined.
hetInit() is called. This will initialize the NHET and copy the NHET code in NHET_RAM. NHET is now running.
mibspiInit() is called. This will initialize the MIBSPI1 according to my previous comments.
mibspiSetData() will copy the data from RAM to MIBSPI_RAM.
mibspiTransfer() will start the mibspi transfer. Because trigger is used, the transfer will only start on a rising edge of HET1_14.
mibspiIsTransferComplete() will check for the completion of the transfer before restarting the sequence.
The CCS project as well as Halcogen project are attached here: 0815.MIBSPI_trigger.zip
Please have a try and let me know if this is useful.
Is it possible to use the NHET as an external trigger for MibSPI? So basically like a GIO pin.
