hi, the breakout-gs document (http://www.gumstix.org/tikiwiki/tiki-index.php?page=breakout+boards) lists the pins on the gs board. however, it is not clear the mapping between pxa and board pins. that is, which io pin of pxa processor is connected to the lcd0, lcd1 etc? pls. let me know. thanks in advance, deva --------------------------------- Yahoo!

Hi Deva, > the breakout-gs document > (http://www.gumstix.org/tikiwiki/tiki-index.php?page=3Dbreakout+boards) > lists the pins on the gs board. however, it is not clear the mapping betw= een > pxa and board pins. that is, which io pin of pxa processor is connected t= o > the lcd0, lcd1 etc? That's covered over here: http://www.gumstix.org/tikiwiki/tiki-index.php?page=3DI%2FO If you look at the Hirose 60 pin connector list, it shows exactly which GPIO pin is being used for what. The PXA255 Developers guide shows which functions are available on which GPIO pin. Here's a link to the PXA255 Developer's guide: http://www.intel.com/design/pca/applicationsprocessors/manuals/278693.htm Look in Chapter 4 (Page 107) for the table which shows how each GPIO pin can be configured. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Hi Dave, thanks for the pointer. although that document is very useful, it doesn't answer the following questions: 1. which uart is connected to CN5? 2. which pins are connected to CN2? pls. let me know. thanks in advance, deva Dave Hylands <dhy...@gm...> wrote: Hi Deva, > the breakout-gs document > (http://www.gumstix.org/tikiwiki/tiki-index.php?page=breakout+boards) > lists the pins on the gs board. however, it is not clear the mapping between > pxa and board pins. that is, which io pin of pxa processor is connected to > the lcd0, lcd1 etc?

I went ahead and added GPIO pin numbers and the Hirose 60 pin pin numbers t= o: http://www.gumstix.org/tikiwiki/tiki-index.php?page=3Dbreakout+boards > although that document is very useful, it doesn't answer the following > questions: > 1. which uart is connected to CN5? I tested with my multimeter and its HWCTS and HWRTS (GPIO 50 & 51). If you have a bluetooth module then I think that these can't be used. > 2. which pins are connected to CN2? GPIO 81, 82, 83, and 84 (see the updated page) -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
