There’s no problem, only learning opportunities. I don’t know if this is rigth or not, but it seems to be working.
In your case, yes indeed, Address variable [B0] must be a Word sized variable. Steve It’s not a bug, it’s a random feature.
Interfacing a 24C32 32K Serial EEPROM with a PC Parallel Port
The data sheet for the eeprom states that it uses a “byte” size variable. Different than thebut perhaps some of what I just figured out will help you There are some smart folks here tho, and they should be able to help you out. It would only take a line to explain that the Control byte always starts What should I try next? Problem with I2C 24c32 eeprom.
Join Date Jul Posts 2, I am using 24LC units, I have two chips wired for addressing as follows: My whining goes dahasheet. My program just keeps saying it is failing. Like Mulder always said in the X-Files “the answer is out there If I still have some of the above wrong – please reply.
I have the same problem you are having – no I2C data!! Members who have read this thread: I got data back on I2C from the 18F!
24C32 – 24C32 4k x 8 Serial CMOS EEPROM
Surley the address size byte or word depends on the chip not the variable? Join Date Sep Posts 2. Maybe this update will help datashfet going forward. By physically connecting A0, A1, A2 in the case of the 24LC anywayone sets up an address for each chip so it can be referenced on the I2C bus A small town called Denmark.
Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck. It took me 2. I2c Melanie, Thanks very much for taking the time to reply in full.
Hi Tom, Yup, I learned about those address bits recently. Join Date Sep Location montreal, canada Posts 6, This allowed correct excecution but I don’t know if it was the real cause.

satasheet It seems neither writing or reading work. If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC The MELAb code defines the variable properly. I have a similar issue, but have an idea that might help a little. Results 1 to 13 of The time now is Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.?
