Python对文件IO操作

本程序实现液晶显示控制器SED1335的字符和汉字显示。 1.显示屏为320*240点阵 2.显示屏前128行为图形方式显示汉字，后112行为文本方式显示字符 3.汉字的Y坐标以象素点为单位，X坐标以8象素点为单位。-This program SED1335 LCD controller display of characters and Chinese characters. 1. Display of 320* 240 dot matrix 2. Display 128 acts of the former graphics display Chinese characters, act after the 112 character text display 3. Chinese characters Y coordinates to pixel-point unit, X pixel coordinates point to 8 units.

,片选接到p1.5 复位端 p1.4 中断端接到 int0 82c250工作在斜率模式下 ，RS 接51k电阻到地。 2，SJA1000与82C250的接口，逻辑上为SJA1000输出0（显性位），表现为低点平输出给82C250，则82C250输出 差分的低电平。SJA1000输出1（隐性位），表现为高电平或悬空输出给82C250，则82C250输出悬空状态。 3,周立功的中SJA_BCANCONF.ASM中对输出控制寄存器 的TX0的输出 极性的位的定义不对。 还有里面定义有接收错误标志码，不知道何时用。-, The election received a P1.5-chip client p1.4 interrupt reset int0 82c250 client received in the slope mode, RS then 51k resistor to ground. 2, SJA1000 with the 82C250 interface, logic for SJA1000 Output 0 (dominant bit), showing low level output to the 82C250, while the low-level differential output 82C250. SJA1000 Output 1 (recessive), and the performance of the output is high or left vacant to the 82C250, the vacant state 82C250 output. 3, Zhou Ligong in the SJA_BCANCONF.ASM of output control register TX0 output polarity bit the definition of wrong. Inside the definition also has to receive error flag code, I do not know when to use.

这是使用汇编语言编写的一个从键盘接受输入，并在屏幕上显示的程序。其中可以输出大小写字符-This is the use of assembly language prepared to accept input from a keyboard and screen procedures. In which case characters can be output

基于凌阳波形发生器的程序，产生三角波，方波，正弦波，100Hz~200KHz-Sunplus based waveform generator procedure, resulting in the triangular wave, square wave, sine wave, 100Hz ~ 200KHz

AD9852驱动，可以产生任意波形。若果有不对的地方，请高手们批评指正。-AD9852-driven, can generate arbitrary waveform. If there is something wrong, please correct me experts have criticized.

用汇编语言编写的简短小巧的记事本程序-assembler language short compact notebook procedures

算十万的阶乘,对于计算机和程序员都是一个挑战,本源程序实现了求大数的阶乘,是用汇编写的,相对速度很快,算十万的阶乘在我赛扬2.4,内存256的神舟笔记本上,用了20多分钟.算出得数写在一个TXT文件下,十万的阶乘结果,用记事本打开,都要好一会儿.-Count of thousands of factorial, for computers and programmers is a challenge to realize the source of the order of the factorial of large numbers, is written in the compilation of a relatively quick, and counting of thousands of factorial in my 2.4 Celeron, memory 256 Shenzhou notebook, spent more than 20 minutes.得数calculated to write in a TXT file, the thousands of factorial results, use Notepad to open, should a good moment.
