I am trying to write and read data fromEEPROM(microcontrollerATmega2560), which gives me the wrong answer. When I debug it, I see that only the last character is being read though I see that data is being written on different addresses. At uiAddress = 1, the data isA, at uiAddress =...

// This program will write 1-14 words to EEPROM and read them back. // The data written and the EEPROM address written to are contained // in the message structure, I2cMsgOut1. The data read back will be // contained in the message structure I2cMsgIn1. // // This program will wo...

当单片机向从器件写入数据时,首先发送一个开始位,然后发送一个从器件的七位地址,第八位是用来告诉从器件我是要读数据还是写数据。1即为Read,0则为Write。然后是一个应答位。然后送寄存器地址,接一个应答,然后开始发送一个字节的数据,再接一个应答位,发送了n个字节后,主器件发送停止位停止传输。

如:sector erase (0x2e00) ;/扇区擦除,第八个扇区byte_program (0x2e00, eeprom_readcode 14、);/写 eeprom,保存可读命令耍读数据时,就直接读就可以了。readdata=byte_read(0x2002);/读取该地址的数据读一个字节、编程一个字节、擦除一个扇区分别用时10us、60us、10ms关于stc系列51单片机的片内eeprom...
谁能帮我在PIC 18上写一个浮点到EEPROM,现在EEPROMYWORD()/Read()不起作用?以前我使用过的方法是使用以前版本的编译器,但现在不再使用了。谢谢你的帮助!! 以上来自于百度翻译 以下为原文 Why MC? why??? Let me calm myself down... Can any one please help me write a float to eeprom on a pic...
I am making a clock using Timer1 of PIC16F1826, every second I am writing a value to the EEPROM inside the MCU, I want to know that how many read write cycles are there in the EEPROM of PIC16F1826 MCU, the data sheet says that "Number of Total Erase/Write Cycles before Refresh" ...
