這是I2c網關Id獨立燒寫程序，
燒寫的ID必須要求是：“0~9”、“a~z”、“A~Z”的16為字符才能燒寫成功。
其中當是輸入的小寫字母時，自動轉換為大些燒入。
如： 1） # ./burnID 0123456789abcdef
燒入的是：0123456789ABCDEF
2] # ./burnID 0123456789@ cdef
燒入不成功，因為有其他字符
3） # ./burnID 0123456789abcdefDfs
燒入也不成，因為超過16個字符

DESCRIPTION
The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes, is optimized to achieve extended battery life in portable measurement applications. The device features a
powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute to maximum code efficiency.
The digitally controlled oscillator (DCO) allows wake-up from low-power modes to active mode in less than 1 μs.
The MSP430G2x13 and MSP430G2x53 series are ultra-low-power mixed signal microcontrollers with built-in 16-
bit timers, up to 24 I/O capacitive-touch enabled pins, a versatile analog comparator, and built-in communication
capability using the universal serial communication interface. In addition the MSP430G2x53 family members
have a 10-bit ANALOG-TO-Digital (A/D) converter. For configuration details see Table 1.
Typical applications include low-cost sensor systems that capture analog signals, convert them to digital values,
and then process the data for display or for transmission to a host system.

From the transition of analog to digital communication along with seamless mobility and
high computing power of small handheld devices, the wireless communications industry has
seen tremendous changes leading to the integration of several telecommunication networks,
devices and services over last 30 years. The rate of this progress and growth has increased
particularly in the past decade because people no longer use their devices and networks for
voice only, but demand bundle contents such as data download/streaming, HDTV, HD video ,
3D video conferencing with higher efficiency, seamless connectivity, intelligence, reliability
and better user experience. Although the challenges facing service providers and
telecommunication companies differ by product, region, market size, and their areas of
concentration but time to market, efficient utilization of their assets and revenue expansion,
have impacted significantly how to manage and conduct their business while maintaining
sufficient margin.

The continued reduction of integrated circuit feature sizes and
commensurate improvements in device performance are fueling the progress
to higher functionality and new application areas. For example, over the last
15 years, the performance of microprocessors has increased 1000 times.
Analog circuit performance has also improved, albeit at a slower pace. For
example, over the same period the speed/resolution figure-of-merit of
ANALOG-TO-Digital converters improved by only a factor 10.

Mobile multimedia communication is increasingly in demand because of the basic need to communi-
cate at any time, anywhere, using any technology. In addition, to voice communication, people have a
desire to access a range of other services that comprise multimedia elements—text, image, animation,
high fidelity audio and video using mobile communication networks. To meet these demands, mobile
communication technologies has evolved from analog to digital, and the networks have passed through
a number of generations from first generation (1G) to fourth generation (4G).

電學中的測量技術涉及范圍非常廣,電流測量在電學計量中占有非常重要的位置。如何精確地進行電流測量是精密測量的一大難題。傳統的電流檢測電路多采用運算放大芯片與片外電流檢測電路相結合的方式,電路集成度很低,需要較多的接口和資源才能完成對電路的檢測。本文把所有電路部分都集成在一塊芯片上,包括檢測電阻,運算放大器電路及模擬轉數字轉換電路,從而在電路內部可以進行電流檢測,使電路更好的集成化。前置電路使用二級共源共柵結構的運算放大器,減小溝道長度調制效應造成的電流誤差。10位SAR ADC中采用電容驅動能力強的傳輸門保證了模數轉化器的有效精度。比較器模塊采用再生鎖存器與遲滯比較器作為基礎單元組合解決精密測量的問題。本設計可以作為嵌入芯片內的一小部分而檢測芯片中的微小電流1mA~100mA,工作電壓在1.8v左右,電流檢測精度預期達到10uA的需求。The measurement technology in electricity involves a wide range,and current measurement plays a very important position in electrical measurement.How to accurately measure current is a big problem in precision measurement. The traditional current detecting circuit adopts the combination of the operational amplifier chip and theoff-chip current detecting circuit, The circuit integration is very low, and more interfaces and resources are needed tocomplete the circuit detection.This topic integrates all the circuit parts into one chip, including detection resistance, operational amplifier circuit andanalog to digital conversion circuit. Highly integrated circuit makes the external resources on the chip more intensive,so that current detection can be carried out inside the circuit, so that the circuit can be better integrated. Thefront-end circuit of this project uses two-stage cascade operational amplifier and cascade tube to reduce the currenterror caused by channel length modulation effect. In 10-bit SAR ADC, the transmission gate with strong capacitivedriving ability ensures the effective accuracy of the ANALOG-TO-Digital converter. Comparator module uses regenerativelatch and hysteresis comparator as basic unit to solve the difficult problem of precision measurement. This topic can beused as a small part of the embedded chip to detect the micro-current in the chip 1 mA~100 mA, the working voltageis about 1.8v, and the current detection accuracy is expected to reach the requirement of 10 uA.

隨著半導體技術的發展，模數轉換器（Analog to Digital Converter，ADC）作為模擬與數字接口電路的關鍵模塊，對性能的要求越來越高。為了滿足這些要求，模數轉換器正朝著低功耗、高分辨率和高速度方向快速發展。在磁盤驅動器讀取通道、測試設備、纖維光接收器前端和日期通信鏈路等高性能系統中，高速模數轉換器是最重要的結構單元。因此，對模數轉換器的性能，尤其是速度的要求與日俱增，甚至是決定系統性能的關鍵因素。在分析各種結構的高速模數轉換器的基礎上，本文設計了一個分辨率為6位，采樣時鐘為1GS/s的超高速模數轉換器。本設計采用的是最適合應用于超高速A/D轉換器的全并行結構，整個結構是由分壓電阻階梯，電壓比較器，數字編碼電路三部分組成。在電路設計過程中，主要從以下幾個方面進行分析和改進：采用了無采樣/保持電路的全并行結構；在預放大電路中，使用交叉耦合對晶體管作為負載來降低輸入電容和增加放大電路的帶寬，從而提高比較器的比較速度和信噪比；在比較器的輸出端采用時鐘控制的自偏置差分放大器作為輸出緩沖級，使得比較輸出結果能快速轉換為數字電平，以此來提高ADC的轉換速度；在編碼電路上，先將比較器輸出的溫度計碼轉換成格雷碼，再把格雷碼轉換成二進制碼，這樣進一步提高ADC的轉換速度和減少誤碼率。
