things i should have probably asked first: have you tried the unicorn hat in raspbian, is it functional? which unicorn hat is it exactly, which pins are you using?, because it looks like there are ones that use spi0 and others spi1 and as for spi: spi@7e204000 is spi0 spi@7e215080 is spi1 spi@7e2150c0 is spi2 which doesn't actually exist on a raspberry pi unless you use the computing module, so it should probably remain disabled _______________________________________________ arm mailing list -- arm@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to arm-leave@xxxxxxxxxxxxxxxxxxxxxxx
