Hello I have a 5402 DSK, and want to use the McBSP1 as a small GPIO port. Could anyone help me with a short C example on how to setup the McBSP1 as GPIO and how to control some of the pins as Output's. Best Regards Jacob |

McBSP as GPIO.

look in the c54x reference set vol 5 (enhanced peripherals), i believe, and you'll find all the mcbsp registers. there'll be a few bits to set the mcbsp for gpio and another few bits to read/write to the pins. specifically look at page 2-96 (p121). you may also want to read the chip support library api reference guide. both of these documents should show up if you search for them at www.ti.com --- In c54x@y..., "fraizzer" <jacob@j...> wrote: > Hello > > I have a 5402 DSK, and want to use the McBSP1 as a small GPIO port. > Could anyone help me with a short C example on how to setup the > McBSP1 as GPIO and how to control some of the pins as Output's. > > Best Regards Jacob |

Thank you. It lead me to this: //Port nr. is CLKRP = 0, CLKXP = 1, FSRP = 2, FSXP = 3. MCBSP_SUBREG_BITWRITE(1, PCR_SUBADDR, iPortNr, 1, 0); MCBSP_SUBREG_BITWRITE(1, PCR_SUBADDR, iPortNr, 1, 1); For setting and reseting the pins in GPIO mode. I chose to setup the McBSP as GPIO from the DSP/BIOS configuration mannager. /Jacob >>>>> "Lucy" == Lucy Jordan <> writes: Lucy> look in the c54x reference set vol 5 (enhanced peripherals), i Lucy> believe, and you'll find all the mcbsp registers. there'll be a Lucy> few bits to set the mcbsp for gpio and another few bits to Lucy> read/write to the pins. specifically look at page 2-96 (p121).
