Python对文件IO操作
filePath="c:/test/tt.txt"
#从文件中读取信息
f=open(filePath, "r")#运用读的方式打开文件,
for line in f: #每次读取文件的一行内容
print(line)
f.close()
#向文件中写入信息
f=open(filePath, "a") #这里有两种方式:第一种是以w的形式,它写入时将会清空以前的数据然后再写入数据,第二种是以a的形式,它以追加的形式写入数据
f.write("我开始向文件中写入信息
")
f.writelines("我已经向文件写入了信息")
f.close()

写汇编代码实现一个圆形的先入先出(FIFO)缓冲器…
To write assembly code to implement a circular First In First Out (FIFO) buffer in the data memory of PIC18F452 microcontroller, using the microcontroller’s direct addressing mode and indirect addressing mode. To expand on the FIFO assignment and implement the FIFO solution on the QWIKFLASH PIC target board and display the FIFOSTATUS as LED indicators. Recall:
Flags within a file register called FIFOSTATUS:
• Bit 0: FIFO_full
• Bit 1: FIFO_empty
• Bit 2: attempt_2_read when FIFO_empty
• Bit 3: attempt_2_write when FIFO_full
