- Makefile.recurse (all): reorder DIRS and TARGET_ONLY_DIRS, so that tools/lib/ gets built before the tools that depend on it - atrf/fw/atspi/ep0.c (do_buf_write): removed duplicate sending of AT86RF230_BUF_WRITE - atrf/fw/atspi/ep0.c (my_setup): generate the PHR in ATSPI_BUF_WRITE instead of expecting the host to send it - atrf/fw/atspi/ep0.c (my_setup): don't send the PHR to the host in AT86RF230_BUF_READ - atrf/fw/include/at86rf230.h (REG_TR_PWR): should be REG_PHY_TX_PWR - atrf/tools/Makefile: added atspi-txrx and "lib" - atrf/tools/atspi-txrx/Makefile: corrected path in F32XBASE - atrf/tools/atspi-txrx/atspi-txrx.c: major rewrite - atrf/tools/include/atspi.h, atrf/tools/lib/atspi.c: functions atspi_buf_write and atspi_buf_read to access the frame buffer
