I wanted to make a step further and made a program which accepts different inputs from serial and changes the types of waveforms. Sign up using Facebook. I checked the program on 8 LEDS and they all workign perfect. We have done that.
Maybe there’s no issue about how it’s done, but is good to be sure about the information that you’re handling. The right way to do it is using timers and counters and interruptions if it’s necessary. He asks to make a sawtooth waveform in 8 bit from Arduino and then connect it Vac0808 to produce an analog signal with an amplifier.

DAC doesn’t want tranfer to analog Ask Question. You can connect leds with a resistance to your output pins and with the square signal you should see some pretty clear behavior. Sign up or log in Sign up using Google. By the way, you can do this the way you’re doing it but as I say, it has its limitations. Or why i doesn’t? For sin wave and tangent wave I suggest to take a look at the casting of the variable float to int. Have you tested your Arduino’s outputs?

For a wave generator it’s not a good idea to generate the signal in the main loop. Dac08808 you are using 8 bits for the output and it is represented with the calcResult variable, maybe you can consider making it a byte or an unsigned char both are basically the same. Hope this can help you with your project a little at least.
Kaspar Siricenko For the bit conversions you do in the final part, maybe you can do it with bit masks. Post as a guest Name. It seems that you are printing the text about the incomingByte all the main loop’s iterations, I think this could be annoying and also takes processing capacity. You should use the periodicity of the signals to do this.
Some things about your project For a wave generator it’s not a good idea to generate the signal in the main loop. He still thinks it’s problem with the cac0808 because his simple version works. Well I was aware of the most of this issues.
