Posted on March 11, 2014 at 21:48I'd like to model if it's practical to drive an STM32 output into a transistor.  I've got some Optimos 3 transistors with a 2.8v Vth:http://www.mouser.com/ds/2/196/BSC340N08NS3G_rev2.6-76670.pdfThe transistor would b...

Posted on February 13, 2013 at 20:22I have an STM32F407 motherboard here connected via SWD, and Keil UVision IDE. I can program, run, halt, and read back registers and all the debugging stuff- EXCEPT the printf() won't show anything in the printf() ...

Posted on December 17, 2012 at 22:26I just started with the STM32F407 Open407I-C board:http://www.wvshare.com/product/Open407I-C-Standard.htmIt's a pretty excellent demo board.  Very little pin commitment on the board, most are just straight brought...

Posted on August 10, 2012 at 22:01I was reading through the documentation on these and saw the ''block data update'' feature, obviously useful because it's two 8-bit registers and it might be possible for the data to update between reads and thus no...

Posted on July 31, 2012 at 12:14I can't quite work this out.  Someone tell me if I'm crazy.LSM303DLHC datasheet is somewhat difficult to read here.  I have CRB_REG_M set to 001, +/-1.3gauss, its most sensitive range.  But all its axes are not equall...
