kristianpaulwhen i do a signed short int read from a memory maped devices, the cpu is supposed to wide/narrow the data bus to fit my requested data type right?14:21
kristianpaulha, nice find indeed :)14:28
wpwrakyes, that's generally what happens. i.e., truncation on writes, zero-padding or sign expansion on reads (details depend on the architecture)14:30
qi-bot[commit] Werner Almesberger: ubb-usb/: concept drawing of simple UBB-USB hardware (master) http://qi-hw.com/p/ben-blinkenlights/540f22415:49
qi-bot[commit] Werner Almesberger: ubb-usb/Makefile: added PDF generation (master) http://qi-hw.com/p/ben-blinkenlights/bdd95bd15:49
Aylawhat's UBB?15:51
wpwrakAyla: this little guy: http://en.qi-hardware.com/wiki/UBB16:02
Aylabut why is a board necessary to get USB with the UBB?16:12
Aylawouldn't bit-banging be a solution?16:12
wpwrakyeah, but you still need to make the physical connection somehow. the Ben doesn't have a USB A receptacle.16:16
wpwrakUBB has already been "mass-produced", so it's something that's readily available (for experiments. once you have the thing working, you can make a neater board)16:17
larscwpwrak: blogic wants to build a 802.15.4. maybe you could give him some hints.18:18
wpwrakah. welcome to the joyful world of RF ! ;-)18:20
blogicwpwrak: i am off to bed, i'll ping you tomorrow if you dont mind19:45
wpwrakblogic: okay. sweet dreams ! :)20:15
Ayla$19 FPGA :)22:36
qi-bot[commit] Werner Almesberger: ubb-usb/pin-change.fig: illustration of how to change multiple pins with a single write (master) http://qi-hw.com/p/ben-blinkenlights/f8185f423:41
