SSCOM32使用說明： 將用戶程序通過串口的方式下載到ATT7025/7027中。 使用步驟： （1）選擇通訊口，然后打開串口，如下圖所示 （2）將DTR打勾，DTR對應芯片的TMS1腳，也就是說通過將DTR打勾將TMS1拉為低電平 （3）將RTS打勾，然后將勾取消，RTS對應芯片的外部復位引腳，通過將RTS打勾將芯片外部復位引腳拉低，使芯片處于復位狀態(tài)，然后將RTS拉高，使得芯片完成復位。 （4）將鼠標移動到上面的大文本框，點擊回車按鍵，然后可以看到有返回信號，如下圖所示： （5）從鍵盤輸入 “M0000” ，會有如下返回信號，如下圖所示，通過這個命令將芯片內的24Kflash擦除 （6）從鍵盤輸入 “M8000” ，會有如下返回信號，如下圖所示，通過這個命令將芯片內的8Kflash擦除 （7）從鍵盤輸入 “E”,如下所示： 說明：鍵入“E”后，不再顯示隨后鍵入的字符，但所鍵入字符可通過串口訪問芯片。 （8）從鍵盤輸入 “L”,此時不會再看到返回字符，然后點擊打開文件，選擇用戶需要下載的hex文件 說明：鍵入“L”是Load命令，此時可以打開一個hex文件進行寫Flash操作。 （9）點擊發(fā)送文件，如下圖所示： （10）當正確傳輸完成時，如下圖所示： 上圖中的情況說明程序下載正確。 （11）將DTR的勾取消，也就是說將芯片的TMS1拉高，將芯片切換到Normal模式，將RTS拉低再拉高，也就是說將芯片復位一次，此時芯片內的程序就開始正常運行了。 軟件標簽: 串口調試 軟件截圖 親 如果您覺得西西能給您帶來幫助請幫西西給個好評下謝謝 ：）

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.

transimpedance linearization circuitry. This allows it to drive video loads with excellent differential gain and phase perfor mance on only 50 mW of power. The AD8001 is a current feedback amplifier and features gain flatness of 0.1 dB to 100 MHz while offering differential gain and phase error of 0.01% and 0.025°. This makes the AD8001 ideal for professional video electronics such as cameras and video switchers. Additionally, the AD8001’s low distortion and fast settling make it ideal for buffer high-speed A-to-D converters. The AD8001 offers low power of 5.5 mA max (VS = ±5 V) and can run on a single +12 V power supply, while being capable of delivering over 70 mA of load current. These features make this amplifier ideal for portable and battery-powered applications where size and power are critical. The outstanding bandwidth of 800 MHz along with 1200 V/μs of slew rate make the AD8001 useful in many general purpose high-speed applications where dual power supplies of up to ±6 V and single supplies from 6 V to 12 V are needed. The AD8001 is available in the industrial temperature range of –40°C to +85°C.

I saw the light of the future when I first read Ray Kurzweil’s best-seller book The Singularity Is Near: When Humans Transcend Biology. One cubic inch of nanotube cir- cuitry, once fully developed, would be up to one hundred million times more powerful than the human brain.

Licensed spectrum remains 3GPP operators’ top priority to deliver advanced services and user experience Opportunistic use of unlicensed spectrum is becoming an important complement for operators to meet the growing traffic demand Moving forward 3GPP operators will have two options to offload traffic to unlicensed spectrum: 1. Wi-Fi (via LTE/Wi-Fi interworking) 2. LTE over unlicensed It will then be up to each individual operator to choose which approach to use, which will depend on a number of factors
