Buy from the Microchip Store. The upper address bits are transferred. Could you please share the logic analyzer output? I took the liberty to format your code a little more so that it can be read more easily. Dxtasheet relevant information from the datasheet is as follows: In order to generate the above sequence, call CreateReadTransaction Functional address lines allow up to eight devices on the same bus, for up to Kbits address space.

I have configured and coded the control registers correctly as per the datasheet. It’s working fine now.

Formatting does not only concern the code but the question as a whole.

Single supply with operation down to 2lc32a. Application Notes Download All. For the SOT and chip scale packages, the address pins are not available. You currently have javascript disabled. The Chip Select bits datqsheet the control byte must correspond to the logic levels on the corresponding A2, A1 and A0 pins for the device to respond.

Stack Overflow works best with JavaScript enabled. I don’t see how that lets me generate this control sequence: Sign up or log in Sign up using Google.

Electronic Solutions for Medical and Fitness. 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. Many thanks for your help – I still have a lot to learn but getting great help like this is always appreciated! What could have possibly gone wrong?

Here is my code below:.

Here are a couple of examples from the 24LC32A datasheet: You create a loop to send a control byte to the device and then parse the ACK looking for a zero at which point datashedt device is ready to accept a new operation.

These bits are in effect the three Most Significant bits of the word address. Here’s the diagram from the datasheet: The Netduino forums have been replaced by new forums at community. For the SOT and chip scale packages, the address. The upper address bits are transferred first, followed by the Less Significant bits. It has been developed for advanced, lowpower applications such as datsheet communications or data acquisition. STOP You’d need 4. It’s easy, but it requires a minimal effort.

I2C + Serial EEPROM (24LC32A)

Sign in anonymously Don’t add me to the active users list. The 24LC32A will datssheet issue an acknowledge and transmit the 8-bit data word. 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 The SOT and chip scale packages do not support multiple device addressing on the same bus.

It is not possible to sequentially. After the word address is sent, the master generates a start condition following the acknowledge. A2 as address bit A
