Generate a Triangle Wave

Connect the module to the Raspberry Pi according to the connection diagram above and set I2C

address to 0x60 by ADDR switch on the module. If I2C address 0x61 is preferred, you need to

modify the parameter of the function mcp4725.setAddr_MCP4725() to MCP4725A0_IIC_Address1.

REF_VOLTAGE can be changed according to the calibration section. If no calibration is done, enter

5000 (5V) or 3300 (3.3V) depending on the VCC power supply.

In the Terminal, type in the following commands and press Enter to run the sample code:

pi@raspberrypi:~ $ cd ~/DFRobot_MCP4725/RaspberryPi/Python/OutputTriangle

pi@raspberrypi:~/DFRobot_MCP4725/RaspbeeryPi/python/OutputTriangle $ sudo pyt

hon OutputTriangle.py

Use an oscilloscope to observe the VOUT output voltage waveform.

The user can modify the parameters in the function mcp4725.outputTriangle() to change

the amplitude, frequency, DC offset and duty cycle of the Triangle wave.
