The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven.

I’m still waiting for some more suggestions. Mar 19, 9. Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that.

I think it would be helpful for me to find a simple application using a SPI. 93d46 19, 8. Mar 16, 1. Mar 16, 4. Mar 16, 2.

Mar 17, 5. Mar 24, EEprom Not reading data Properly Any sugestion would be very helpful.

I will get the pins layout soon. And this one I’d like to adapt to a 12Vdc installation. The rest of connections not related to this circuit. Posted by kishore in forum: Basically, this helps in saving one IO Pin. Do you think should be another approach? Mar 20, I can not split the pins 3 and 4.

Thanks Rama but this is what I get it: It appears that you are reading mirror pins. If not then more drastic measures will be required including a “vampire” connector that taps into the existing circuitry or desoldering and isolating the chip so that you can 9346 to the signal lines without interference.

DI and DO together. The 93C46 is a memory element.

I know nothing about the SPI in the original motherboard circuit. Either the existing board was designed to allow the contents to be read or it wasn’t. Then you could use standard SPI. I need to identify each of the 8 pins of the other circuit and see what connections need to be done. I was wondering if there is not an applcation similar to my case or maybe we’ll declare as new descovery.

Mar 23, No, create an account now. Embedded Systems and Microcontrollers. If you have to use this you need to use the resistors as in the AN, you need to write a bit bang SPI taking care of timing requirements!

Reading the data of a 93C46 eeprom Reply to Thread. I have also an Arduino Eleven or Uno equivalent with 4 related terminals: The question here is as follows: For the command streams sent to 93C46 all start, cmd or opcode, addresprom they are not multiples of 8 bits, then you can pad it up with 0 at the beginning. Look up SPI for those details.

Yes, my password is: Do you already have an account? Mar 16, 3.

Reading the data of a 93C46 eeprom

I am looking for a link or a simple application to be used in reading the data of a eeprom type 93C46 circuit used for counting the number and duration of activations of a 12V DC power source. It needs some sort of controller to use it as it works over a serial interface. Mar 22,
