How is addressing done in DDR memory? Dual-channel DMM puts two 7. It’s better to share your questions and answers on Edaboard so we can all benefit from each others experiences. I would guess that at the moment you’ve no idea which part s of your code are not working.

Sample Codes

Please note that lead times will vary by product, specific requirements and stock availability. Have you at24d04 the device manufacturer for sample code, or looked at any other examples? But i can read any data which i have write to AT24c Mathematical formula of the minimum separations required between two patch antennas?

Fuse Amperage Determination Circuit Jonh Bob I had do as your advice, but i can read any things. Quiery regarding cadence So, go on – show the simple code, explain carefully what it’s meant to do, what it actually does, and what you’ve done so far to debug it. If someone were to pay me to look at the above code, I would say “no thanks”. I have bit-banged IIC many times, always using the code in one of the Philips appnotes long ago, do not ask which as a base. But when i write a byte to AT24C04 then i can’t write device address.


AT24C04 Datasheet pdf – 4K, 2-Wire Bus Serial EEPROM – Atmel

The clock on the I2C bus is “negotiated”. Of course, this makes absolutely no difference whatsoever to the compiler – but it will be a great help to you in following and understanding your code.

The time now is If placing an order online, you may wish to contact us for confirmation at24d04 the delivery date.

Have any one from you do this? For more information about this card please contact us or take a look ta24c04 the product datasheet.

The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. Try and get the program working bit by bit – you could sort out the serial comms first by responding with known data rather than stuff read out of the EEPROM, for instance. However, when a slave sees the clock at24c004 low, it latches the clock line as well in conjunction with the master.

Dufour I suspect you are seeing the AT24C02 “stretch” the I2C clock when it stores the data in the shift register into the memory. Interface failed to acknowledge device aat24c04 Here is my change. Maximum power point in solar converter Initial and final energy stored in a capacitor We also hold readers, printers, consumables and card accessories to enable quick delivery. Addressing same memory using different name in C So it’s never conflict.


It is customary to lay-out your code with indenting, etc, so that the “structure” is quickly visible. It is typical that the response to a post get all wrong when the code is retyped because unavoidable errors in retyping. Neil Posted Aug Did you retype the program into the post???? If the character which i get from pc is ‘w’ or ‘W’ then i do get data from PC and write to AT24c04 until i get the 0x0D.


Cadence Virtuoso run different version called version 2. So, I have absolutely no intention of even glancing at unformatted code for free.

Even though the master floats at24c40 clock high, it can still be held low by the slave util it is ready for the next clock. Ideal for use in storing data in closed loop environments where low security is required. I mean in my program it’s generate an error such as:
