Mega16是一款采用先進(jìn)RISC精簡指令，內(nèi)置A/D的8位單片機，可支持低電壓聯(lián)機 Flash和EEPROM 寫入功能；同時還支持 Basic和C 等高級語言編程。用它設(shè)計電子時鐘不僅成本低，硬件簡單，而且很容易實現(xiàn)系統(tǒng)移植。介紹了如何利用AVR系列單片機Mega16及1602字符液晶來設(shè)計電子時鐘的方法，同時給出了相應(yīng)的電路原理及部分語言程序。 Abstract: ?Mega16 is a high-performance, low power consumption, the use of advanced RISC concise instructions, built-in A/D 8-bit microcontrollers, the on-line support for low-voltage Flash, EEPROM write function. Except Mega16 also support the Basic, C, and other high-level language programming.The electronic clock which is deisgned by Mega16 is not only low-cost, simple hardware, but easy to achieve system migration.The design method of electrioic clock based on the AVR Mega16 and Character LCD1602 is introduced in this paper,and the corresponding circuit electrionic and some language program are given.

1 Communication Protocol (Computer as master) The communication protocol describes here allows your computer to access 4096 internal registers (W0000-W4095) and 1024 internal relays (B0000-B1023) in the Workstation.. 1.1 Request Message Format Request message is a command message to be sent from the computer to the Workstation. The data structure of request message is shown below. Note that numbers are always in hexadecimal form and converted into ASCII Characters. For example, Workstation unit number 14 will appear in the message as Character 0(30h) followed by Character E(45h); a BCC of 5Ah will appear in the message as Character 5(35h) followed by Character A(41h).

This example provides a description of how to use the USART with hardware flowcontrol and communicate with the Hyperterminal.First, the USART2 sends the TxBuffer to the hyperterminal and still waiting fora string from the hyperterminal that you must enter which must end by '\r'Character (keypad ENTER button). Each byte received is retransmitted to theHyperterminal. The string that you have entered is stored in the RxBuffer array. The receivebuffer have a RxBufferSize bytes as maximum. The USART2 is configured as follow: - BaudRate = 115200 baud - Word Length = 8 Bits - One Stop Bit - No parity - Hardware flow control enabled (RTS and CTS signals) - Receive and transmit enabled - USART Clock disabled - USART CPOL: Clock is active low - USART CPHA: Data is captured on the second edge - USART LastBit: The clock pulse of the last data bit is not output to the SCLK pin

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a Character format.

The government of a small but important country has decided that the alphabet needs to be streamlined and reordered. Uppercase letters will be eliminated. They will issue a royal decree in the form of a String of B and A Characters. The first Character in the decree specifies whether a must come ( B )Before b in the new alphabet or ( A )After b . The second Character determines the relative placement of b and c , etc. So, for example, "BAA" means that a must come Before b , b must come After c , and c must come After d . Any letters beyond these requirements are to be excluded, so if the decree specifies k comparisons then the new alphabet will contain the first k+1 lowercase letters of the current alphabet. Create a class Alphabet that contains the method choices that takes the decree as input and returns the number of possible new alphabets that conform to the decree. If more than 1,000,000,000 are possible, return -1. Definition
