Anyone working on MCP4728 (12-Bit, Quad Digital-to-Analog Converter with EEPROM Memory) driver?

Hi friends,

Is there anyone working on establishing MCP4728 (12-Bit, Quad Digital-to-Analog Converter with EEPROM Memory) driver?

I am recently working on DAC expander for my device. I found the driver for MCP4725 which has only a single channel. Now I wish to have more channels, so I found MCP4728 from the web. However, it seems no one has posted any driver related to this 4-channel DAC expander. I tried to modify the driver of MCP4725, but it seems a little difficult for a newbie like me.

Thank you in advance.

OK, maybe no one has sort of driver.

Hello, I just faced the same problem and adapted Adafruit_CircuitPython_MCP4728 library by Bryan Siepert to microPython. It looks like working OK. Here is it: https://github.com/openfablab/mcp4728
