The next two bytes received define the address of the first data byte Figure It’s working fine now. STOP The problem is the highlighted start signal in the middle of the sequence – there’s no preceding stop so I have to be able to generate a start signal in the middle of the control sequence transaction.

I fixed up the code and now it works perfectly – the logic analyzer output looks exactly like dataaheet datasheet.

It’s easy, but it requires a minimal effort. STOP You’d need 4. When I tested with the 4.

I don’t see how that lets me generate this control sequence: The SOT and chip scale packages do not support multiple device addressing on the same bus.


The datasheet describes an ‘Acknowledge Polling Flow’ which allows the code to loop while waiting for a write operation on the device to complete.

In this case, software can use A0 of the con. During dataasheet addressing, the. Thank You m00am, i am sorry for the messy and unformatted code since I am not much of a coder.

I2C + Serial EEPROM (24LC32A)

Chris Thanks Chris, that was the bit I was missing! Electronic Solutions for Medical and Fitness. In this case, software can use A0 of the con- trol byte as address bit A12; A1 as address bit A13; and A2 as address bit A Corporate Product Selector Guide.

You currently have javascript disabled. AN – Interfacing I2C? The Netduino forums have been replaced by new forums at community. A control byte is the first byte received following the. The control byte consists of a four-bit control code.

The relevant information from the datasheet is as follows: Sign up using Facebook. The 24XX32A also has a page write capability for up to 32 bytes of data. The Microchip Technology Inc. So the thing is that the writing of the data is not taking place. The last bit of the control byte defines the operation to. Formatting does not only concern the code but the question as a whole.

The upper address bits are transferred first, followed by the Less Significant bits. The repeated start condition fix seems to just be adding extra bytes immediately after the initial start signal. I totally misunderstood what that address was – I thought it was the device address.

Please log in to reply. Functional address lines allow up to eight devices on the same bus, for up to Kbits address space. The next three bits of the control byte. The Chip Select bits in the control byte must correspond to the logic levels on the corresponding A2, A1 and A0 pins for the device to 24l3c2a. Verilog Model – 24xx32A Devices.
