Thank You m00am, i am sorry for the messy and unformatted code since I am not much of a coder. You create a loop to send a control byte to the device and then parse the ACK looking for a zero at which point the device is ready to accept a new operation.

The ‘Random Read Sequence’ which datashedt a byte to be datasbeet from a specified address requires a control sequence that includes a start signal high to low transition on the SDA line while SCL is high in the middle like this: Please log in to reply.

A1 and A0 pins for the device to respond. I have configured and coded the control registers correctly as per the datasheet. To perform a random read operation, first the word address must be set. Application Notes Download All. I am using uvision 5 Keil to code my program. It is not possible to sequentially.

I fixed up the code and now it works perfectly dstasheet the logic analyzer output looks exactly like the datasheet. Verilog Model – 24xx32A Devices. The Chip Select bits in the control byte must.

Functional address lines allow up to eight devices on the same bus, for up to Kbits address space. Many thanks for your help – I still have a lot to learn but getting great help like this is always appreciated! The next three bits of the control byte. The Netduino forums have been replaced by new forums at community. I’ve forgotten my password. It has been developed for advanced, lowpower applications such as personal communications or data acquisition.

When set to a zero, a write operation is selected. A2 as address bit A Email Required, but never shown. AN – Interfacing I2C?

It’s easy, but it requires a minimal effort. Stack Overflow works best with JavaScript enabled. 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 datsaheet a start signal in the middle of the control sequence transaction.
