- tools/lib/atusd.c (spi_send_partial, spi_send): removed the old spi_send and renamed spi_send_partial to spi_send - tools/lib/atusd.c (atusd_cycle, spi_send, spi_recv, atusd_open): updated for removal of SLP_TR and split of MxSx into MOSI and MISO - tools/lib/atusd.c (atusd_reset_rf, atusd_open): added delays to precharge the capacitors - tools/lib/atusd.c (atusd_reset, spi_data_in, spi_data_out, spi_finish): removed functions for obsolete hardware features - tools/lib/atusd.c (atusd_reg_read): removed calls to removed functions - tools/lib/atusd.c (atusd_buf_write, atusd_buf_read, atusd_driver): new buffer read/write functions - tools/atspi-txrx/atspi-txrx.c (init_txrx): set the internal osciallator trim only in the USB version. Switch to the external oscillator in the uSD version. - tools/atspi-rssi/atspi-rssi.c (sweep), tools/atspi-txrx/atspi-txrx.c (set_channel): wait for the PLL to settle after setting the channel - tools/include/atspi.h, tools/lib/atspi.c (atspi_interrupt), tools/lib/driver.h (struct atspi_driver), tools/lib/atusd.c (atusd_interrupt): new function to poll the interrupt line - tools/atspi-txrx/atspi-txrx.c (receive): only read REG_IRQ_STATUS if there is a pending interrupt - tools/atspi-id/atspi-id.c (usage): print "usage:" as well - tools/Makefile (upload): upload the atspi tools to the Ben
