Werner Almesberger	7fd9044d94	atusb/fw/: add SPI block reception ... This decreases the retrieval time for a frame of 102 bytes from 660 us to 384 us, corresponding to a speed change from about 1.26 Mbps to 2.17 Mbps (102 bytes plus 2 bytes overhead).	2013-07-30 19:52:54 -03:00
Werner Almesberger	ec7c93789a	atusb/fw/: added "lazy enabling" of UART-SPI after ATUSB_GPIO ... - spi.h (spi_off), spi.c: disable the UART - spi.c (spi_initialized, spi_begin, spi_init): initialize the UART if necessary - board_app.c (gpio): call spi_off to disable the UART instead of open-coding the operation - board_app.c (gpio): don't explicitly re-enable the UART but defer it to the next communication	2011-06-09 14:02:26 -03:00
