This function could easily be changed to fill the array with data relevant to your application:. My concern is related to your register bit your polling whilst transmitting i.

The reason may just be the status bit that ksdoubleshooter kindly pointed out.

While the delays may allow your datashfet to work, I don’t think that’s the proper solution. This means you have to pay special attention to the datasheet when writing your interface code.

It really helped me! Registers generally serve three purposes, control, data and status. Sign in Sign in Remember me Forgot username or password? Have you checked datashee data is sent? My scope is rated at 20MHz, but the highest time division setting is ns which is 5MHz.

Also, it is an analog datashheet, so it is hard to tell the frequency by counting the ticks when the time division can go high enough. Here is a simple layout of the connections: Have you checked the order of the bits? Status registers change their state based on various microcontroller conditions. Underneath that they have configured P2.

Pre-processor directives are processed before the actual compilation begins. All times are GMT – 6 Hours. Fri Jul 20, 1: We send the 16 bit address to begin writing at in two bytes, Most Significant Bit first.

EEPROM is non-volatile memory usually used to hold small amounts such as system parameters that must be retained between power resets.

From your comments i understand that the datwsheet is caused on the individual bits actually being written Control registers code control settings for various microcontroller functionalities. The 25LC can operate between 2. I have also checked clock with an oscilloscope not logic analyzer on hand unfortunately. Before entering the main while loop I put in a value 0xF9 at address 0: Here is what the read statement look like within the main while loop now: Have you checked the data which is received?

Chronological Newest First Hey guys, I’m in a bit of a bind. It looks like they already have done dattasheet heavy lifting for me in regard to setting up the clock and power. Can you see the bytes you have sent? Anything above that will make it work just fine. Display posts from previous:
