Hi, i tried to generate analog output voltage by Arduino due in simulink using MCP4725. But the file does not work, and gives an error. It says code generation file does not exist.I have used the files provided in the official mathworks website by one person.Could you please let me know how to use it.The link of files is given: https://in.mathworks.com/matlabcentral/fileexchange/82480-mcp4725-12-bit-dac-i2c-block-for-arduino-due?s_tid=prof_contriblnk

Hi,

I found the solution. I used I2C communication block provided by MATLAB, It worked well. Thanks MATHWORKS :)

Hi,

i want to use the MCP4725 in simulink 2023 with the Raspberry Pi 4B. Did you use the I2C Controller write block? How did you configure the block? Did you need to install libraries on the raspberry pi, or include headers somewhere ? Could you provide a simple slx example? Please i need help

Hi,

I used Arduino Due (Not Rasberry Pi) for MCP4725. You need to check only the Peripheral address. Put number 96 or 97, which are corresponding to 0x61 and 0x62, rewspectively, as far as I remember.
