I2C EEPROM

[AnWa]

Hi!

I am designing a circuit where a PicAxe-20M2 needs to talk to an EEPROM (24C65-I/SM) over I2C. Unfortunately, there is no such block in Blockly and I am not able to write such a routine in assembler.

Any advice?

Edit: Here is the circuit diagram
I only need the PicAxe to read and write a handful of integers.

Hi,

See section 7 in manual5 (Blockly) : https://picaxe.com/docs/picaxe_manual5.pdf
Write and read blocks I2C are in the Advanced menu of Picaxe Editor.

And some Basic instructions can be embedded into a Basic block.

Thank you. I'm on a Mac so I didn't know about the features available to PC users.

I think I will try to fit the data into the PicAxe's internal memory instead.

I didn't know Mac users had these restrictions for Blockly.
You can use a Windows emulator to install Picaxe Editor 6, otherwise perhaps with Blockly Cloud.

All versions of PICAXE Blockly on all platforms have the eeprom i2c commands in the 'Advanced' section
