    SSCOM32使用说明: 将用户程序通过串口的方式下载到ATT7025/7027中。 使用步骤: (1)选择通讯口,然后打开串口,如下图所示 (2)将DTR打勾,DTR对应芯片的TMS1脚,也就是说通过将DTR打勾将TMS1拉为低电平 (3)将RTS打勾,然后将勾取消,RTS对应芯片的外部复位引脚,通过将RTS打勾将芯片外部复位引脚拉低,使芯片处于复位状态,然后将RTS拉高,使得芯片完成复位。 (4)将鼠标移动到上面的大文本框,点击回车按键,然后可以看到有返回信号,如下图所示: (5)从键盘输入 “M0000” ,会有如下返回信号,如下图所示,通过这个命令将芯片内的24Kflash擦除 (6)从键盘输入 “M8000” ,会有如下返回信号,如下图所示,通过这个命令将芯片内的8Kflash擦除 (7)从键盘输入 “E”,如下所示: 说明:键入“E”后,不再显示随后键入的字符,但所键入字符可通过串口访问芯片。 (8)从键盘输入 “L”,此时不会再看到返回字符,然后点击打开文件,选择用户需要下载的hex文件 说明:键入“L”是Load命令,此时可以打开一个hex文件进行写Flash操作。 (9)点击发送文件,如下图所示: (10)当正确传输完成时,如下图所示: 上图中的情况说明程序下载正确。 (11)将DTR的勾取消,也就是说将芯片的TMS1拉高,将芯片切换到Normal模式,将RTS拉低再拉高,也就是说将芯片复位一次,此时芯片内的程序就开始正常运行了。 软件标签: 串口调试 软件截图 亲 如果您觉得西西能给您带来帮助请帮西西给个好评下谢谢 :)

  • MSP430G2553

    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.

  • AD8001AR

    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.

  • The Cognitive Early Warning Predictive System

    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
