[2014/04/03] bcm2835 版本更新至 1.36
1.36 Make automake's test runner detect that we're skipping tests when not root, the second one makes us skip the test when using fakeroot (as used when building Debian packages). Contributed by Guido Günther.
1.35 Fix build errors when compiled under Qt. Also performance improvements with SPI transfers. Contributed by Udo Klaas.
1.34 Added bcm2835_i2c_write_read_rs() which writes an arbitrary number of bytes, sends a repeat start, and reads from the device. Contributed by Eduardo Steinhorst.
1.33 Added command line utilities i2c and gpio to examples. Contributed by Shahrooz Shahparnia.
1.32 Added option I2C_V1 definition to compile for version 1 RPi. By default I2C code is generated for the V2 RPi which has SDA1 and SCL1 connected. Contributed by Malcolm Wiles based on work by Arvi Govindaraj.
1.31 Fix a GCC warning about dummy variable, patched by Alan Watson. Thanks.
1.30 10 microsecond delays from bcm2835_spi_transfer and bcm2835_spi_transfern for significant performance improvements, Patch by Alan Watson.
1.29 Further fix to SPI from Peter Würtz.
1.28 Fixed a problem where bcm2835_spi_writenb() would have problems with transfers of more than 64 bytes dues to read buffer filling. Patched by Peter Würtz.
1.27 bcm2835_gpio_set_pad() no longer needs BCM2835_PAD_PASSWRD: it is now automatically included. Added suport for PWM mode with bcm2835_pwm_* functions.
1.26 Added missing unmapmem for pads in bcm2835_close to prevent a memory leak. Reported by Hartmut Henkel.
