Changing the SPI pinouts

[ravipurigen]

Is it possible to change the SPI pinouts defined in tlc5947.py to use the following instead ? Seems like it is hardcoded in the bmc2835_spi_begin() function defined in bcm2835.c
GPIO38 - SPI0_MOSI
GPIO39 - SPI0_SCLK
GPIO36 - SPI0_CE0_N

Is this for Raspberry Pi?

[ravipurigen]

Yes, the bcm2835 library seems to have hardcoded the SPI pins to use 7-11 in, so I am guessing I will have to rebuild that one and there's no modification needed on the fpulse side, right ?

Is it possible to assign different GPIOs than the default one to SPI in Raspberry Pi?

[ravipurigen]

Yes, line number 1273 at https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README
I ran the spidev_test.c to confirm it and the default SPI pins gets disabled after adding that line to the /boot/config.txt
