Hello all! I'm looking for any help or suggestions. I'm very new to Arduino and still learning the basics. I'm trying to use a mcp4725 DAC and Arduino mega to generate a fixed frequency sine wave tone(preferably 800Hz but up to 1000Hz is fine) to use as a homebrew CW IDer for a repeater. I have some code but it only outputs around 50Hz. How do I get to the frequency I need? Thanks for any and all help!!
