Hi Paul, your new code does not make mmap error anymore. But it is not correct, from documentation: Physical addresses range from 0x20000000 to 0x20FFFFFF for peripherals. The bus addresses for peripherals are set up to map onto the peripheral bus address range starting at 0x7E000000. Thus a peripheral advertised here at bus address 0x7Ennnnnn is available at physical address 0x20nnnnnn. This correspond well to what is coded for GPIO line accees in the code. So we have to use:
#define BCM2835_PADS_GPIO_0_27 (BCM2835_PERI_BASE + 0x100000) Cheers -- Nicolas Produit ISDC, Data Centre for Astrophysics Phone:+41 22 379 2140 16, Chemin d'Ecogia Fax: +41 22 379 2133 CH-1290 Versoix www: http://isdc.unige.ch/~produit ------------------------------------------------------------------------------ LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
