Thanks for taking your time for troubleshooting this problem. Although this could also give you the right behavior, it’s a better way to use a boolean or a char taking 0 and 1 values. Have you tested your Arduino’s outputs? Veve 5, 5 26 Sign up or log in Sign up using Google.

DAC doesn’t want tranfer to analog Ask Question. Post as a guest Name. Maybe there’s no issue about how it’s done, but is good to be sure about the information that you’re handling. This also happens with squareCheck.

But when we tried to check the working circuit for somereason it didn’t want to work. Well I was aware of the most of this issues.

Take a look at the tangent wave, there da0c808 the same problem with the overflow that I’ve mentioned in the sine wave. If you’re not sure about your DAC, you could test it using a dip switch. 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. And the last sac0808 make a program in the wiring language. He still thinks it’s problem with the code because his simple version works.

This would be cleaner and easier to handle. 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.

The right way to do it is using timers and counters and interruptions if it’s necessary.

Kaspar Siricenko The variable triangleCheck is always increasing, this will cause you overflow. Or why i doesn’t? Daf0808 we made an a circuit.

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. Then started to do the calculations and expected results. Sign up using Facebook. For the bit conversions you do in the final part, maybe you can do it with bit masks.

The da0c808 sure the problem is dac8008 my complex problem rather then in my circuit or maybe with my processor, but I noticed very strange voltage output. I checked the program on 8 LEDS and they all workign perfect.

How to use a DAC with the arduino

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. By the way, you can do this the way you’re doing it but as I say, it has its limitations. For sin wave and tangent wave I suggest to da0808 a look at the casting of the variable float to int. Using counters you could also control the frequency of your output signal.

But we put i ht ecircuit and check on osciliscope it shows 9. You can connect leds with a resistance to your output pins and with the square signal you should see some pretty clear behavior.

You should use the periodicity of the signals to do this. I wanted to make a step further and made a program which accepts different inputs from serial and changes the types of waveforms.
