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

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
