I used them in an application as it was done here: http://www.8devices.com/wiki_carambola/ ... cd_display Have a look at the sources there and copy / edit the mmio stuff as you need it. For my purposes, I copy-pasted those parts and edited them to drive a Nokia 5110 serial driven LCD. |

Hi, did you see this tutorial? http://www.8devices.com/wiki_carambola/ ... io_control It should be helpful. BTW, if you use gpioctl with io>12 you get error at first use. It is scary, but still works. |

There has to be at least one person who got the spi pins to work as normal gpio pins. Please, someone provide this info. I need the spi gpio pins to continue with my project. I would also give a reward of 20 bucks! Thats how desperate i am right now^^ |
