We consider basic notions of security for cryptographic hash functions: collision resistance, preimage resistance, and second-preimage resistance. We give seven different definitions that correspond to these three underlying ideas, and then we work out all of the implications and separations among these...
*B 6 FM3 Microcontroller PWM Waveform Generation by Multi-function Timer Example 2 of output waveform The change from Example 1 of output waveform is only to write "1" to the CMOD bit in the OCSB10 register. In case that OCSB10...
根据说明文件Using the USCI I 2C Master(Rev.A)(SLAA382A) 对 TI_USCI_I2C_master.h 中的SDA_PIN 和 SCL_PIN 做了修改(改为P1.6与P1.7的地址依次为0x40,0x80)及include了MSP430G2553的头文件,但是在尝试使用Checking Presence of a Slave(检测线上的s...
these clicks come from the main processor's clock. So basically, counting time (waiting 10 minutes) is a matter of waiting for a certain amount of cycles to happen. There is a "special way" of using the timer, in which the clicks come...

It can be used for timebase generation with interrupt generation on timer overflow. 3.12 Beeper The STM8L001J3 devices include a beeper function used to generate a beep signal in the range of 1, 2 or 4 kHz when the LSI clock is operating at a frequency of 38 kHz. 3.13 Infrared (IR)...
The combination of an ultra-low power real-time clock, PCF2123 or PCF8523, with the microcontroller will reduce the system power consumption in the standby mode by up to a factor of 30. In most systems, since the off-time is magnitudes greater than the on-time, this will bring a signif...
In the test application, I toggle the state of a single LED. In the version loaded via the bootloader, I toggle the states of two LEDs. Both scenarios work without any problems. Compared to the test code, the application code where I encountered the problem inclu...
