Computes all eigenvalues and eigenvectors of a real symmetric matrix a, ! which is of size n by n, stored in a physical np by np array. ! On output, elements of a above the diagonal are destroyed. ! d returns the eigenvalues of a in its first n elements. ! v is a matrix with the same logical and physical dimensions as a, ! whose columns contain, on output, the normalized eigenvectors of a. ! nrot returns the number of Jacobi rotations that were required. ! Please notice that the eigenvalues are not ordered on output. ! If the sorting is desired, the addintioal routine "eigsrt" ! can be invoked to reorder the output of jacobi.

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 :)
