Or why i doesn’t?
The right way to do it is da0808 timers and counters and interruptions if it’s necessary. Sign up or log in Sign up using Google. You should also consider that the tangent is an unbounded function so it will have lot of values over the that your DAC accepts.
DAC Technical Data
DAC doesn’t want tranfer to analog Ask Question. Well I was aware of the most of this issues.
Have you tested your Arduino’s outputs? And the last we make a program in the wiring language.
DAC 0808 LCN
Hope this can help you with your project a little at least. Kaspar Siricenko 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. Post as a guest Name. By the way, you can do this the way you’re doing it but as I say, it has its adc0808. You can connect leds with a resistance to your output pins and with the square signal you should see some pretty clear behavior.
I wanted to make a step further and made a program which accepts different inputs from serial and changes the types of waveforms.

The lecturer sure the problem is in my complex problem rather then in my circuit or maybe with my processor, but I noticed very strange voltage output.
The variable triangleCheck is always increasing, this will cause you overflow. Maybe there’s no issue about how it’s done, but is good to be sure about the information that you’re handling. Take a look at the tangent wave, there is the same problem with the overflow that I’ve mentioned in the sine wave. Thanks for taking your time for troubleshooting this problem.
How to use a DAC with the arduino
For the bit conversions you do in the final part, maybe you can do it with bit masks. Join Stack Overflow to learn, share knowledge, and build your career. For a wave generator it’s not a good idea to generate the signal in the main loop.
Some things about your project For a wave generator it’s not a good idea to generate the signal in the main loop.
Because 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. For sin wave and tangent wave I suggest to take a look at the casting of the variable float to int.
This is because in a digital signal generator is important the sample frequency and the wave frequency, and generating the wave in the main loop could make delays that alters the frequency. You should use the periodicity of the signals to do this. We have done that. Then started to do the calculations and expected results. He asks to make a sawtooth waveform in 8 bit from Arduino and then connect it DAC to produce an analog signal with an amplifier.
