1.McBSP interrupts on Texas 2812
I have problems with the receive and transmit interrupts on this DSP. I have
set the McBSP to generate interrupts on RRDY and XRDY, and I can see that
these bits are set when I emulate the program on my hardware (using XDS510PP
Plus and CCS). This should also have activated the corresponding interrupt
flags in the PIEIFR6 regsiter (bit 5 and 6), but this does not happen.
I can see that my ISRs are working if I set the interrupt flags in PIEIFR6
manually, so the problem is the connection between the McBSP and the PIEIFR6
register. What do I have to do to make the McBSP RRDY and XRDY activate the
flags in PIEIFR6 ?
I use the internal sample rate generator, and I can see the frame and clock
signals with my oscilloscope.
Thank you in advance.
2.hwo to set up interrupt in dsp 2812
I am new in using dsp 2812.
I want to make an T3PINT interrupt.
I just read "TMS320x281x DSP System Control and Interrupts Reference
"TMS320x281x DSP Event Manager (EV) Reference Guide"(spru065e),
On page 84 in spru065e,and on page 122 in spru078e,
what's mentioned in the priority field seems different.
I am traceing the C of the example "sw_prioritized_interrupts"
mentioned in the document "C281x C/C++ Header Files and Peripheral
It seems that cpu branchs to ISR to setup priority.Is this the way it
does? Or Is my understanding wrong?
If priority can be set in code,why priority are mentioned in these
Dose someone know how to accomplish this task?
Thanks a lot for your answers
3.own api flashing dsp 2812
I work on a 2812 dsp board, I make a c# application to test it and now
want to flash it.
On this board i have four Dsp (not interconnected), i use SDFlash wit
four com port and four sdp project.
I can create a process which will launch four SDFlash.
Does SdFlash can take arguments in a command line, like this ?
An other idea is to create my own window working like SDFlash.
In this case, do you know if it's possible to have SDFlash source code
or informations about c++ input methods that i can call to flash dsp.
A last question, does it exist an industrial method to flash more fastly
thank you for your help.
4.ADC's noise on DSP 2812
Hi everybody !!!
Can someone help me to solve the following problem ?
I need to use an external signal in my program in order to make a goo
enslavment of a signal.
So what, i want to get a very accurate value of my external signal.
I use the ADC module of the DSP 2812 but when I look a the value returne
there's a lot of noise on it.
Can someone explain me why this measure is so noisy and how i coul
improve it ?
Thanks a lot
5.DSP-2812: Calling SCI_BOOT from the program
I want to call SCI_BOOT in my program in order to use SDFlash to update
the flash. The resistors are set up in such a way that it boots from
flash and I don't want to change that. Or can the DSP-resetted in such
a way that it ignores the hardware and boots from SCI_BOOT anyway.
Kind regards, Frank
