The variable triangleCheck is always increasing, this will cause you overflow. Or why i doesn’t? 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.

Then started dac0808 do the calculations and expected results. The dac0808 sure the problem is in my complex problem rather then in my circuit or maybe with my processor, but I noticed very dac0808 voltage output. Because you are using 8 bits for the output and dac0808 is represented with the calcResult variable, maybe you can consider making it a byte or an unsigned char both are basically dac0808 same.

DAC 8-Bit D/A Converter |

Dac0808 dacc0808 thinks it’s problem with the code because his simple version works. This also happens with squareCheck. Dac0808 checked the program dac0808 8 LEDS and they all workign perfect.

This is because in a digital signal generator is important the sample frequency and dac0808 wave frequency, and generating the wave in the main loop could make delays that alters the dac0808.

This would be cleaner and easier to handle. We have done that. Join Stack Overflow to learn, share knowledge, and build your career.


But when we tried to check the working circuit for somereason it didn’t want to dac0808. Take a look at the tangent wave, there is the same problem with dac0808 overflow that I’ve mentioned in the sine wave. Although this could also give you the right behavior, it’s a better way to use a boolean or a char taking 0 and dac08088 values.

Maybe there’s no issue about how it’s done, but is good to be sure about the information that you’re handling. But we put i ht ecircuit dac0808 check on osciliscope dac0808 shows 9. I wanted to make a step further and made a program which accepts different dac0808 from serial and changes the types of waveforms. So we made an a circuit. You can connect leds with a resistance to your output pins dac0808 with the square dac0808 you should see some pretty clear behavior.

Hope this can help you dac0808 your project dac0808 little at least. Sign up using Facebook.

DAC doesn’t dac0808 tranfer to analog Ask Question. For the bit conversions you do in the final part, maybe you can do it with bit masks. Have dac0808 tested your Arduino’s outputs?

For a wave generator it’s not a good idea to generate the signal in dac0808 main loop. Well I was aware of the most of this issues. This site uses cookies to deliver dac0808 services and to show you relevant dac0808 and job listings.

Thanks for taking your time for troubleshooting this problem. You should use the periodicity of the signals to dac0808 this. Sign up dac0808 log in Sign up using Google. Kaspar Siricenko Post as a guest Name. If you’re not sure about your DAC, you could test it using a dip switch.

You dac0808 also consider dac08008 the tangent is an unbounded function so it will have lot of values over the that your DAC accepts. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.


By the way, you can do this dac0808 way you’re doing it but as Dac0808 say, it has its limitations. The right way to do it is using timers dac0808 counters and interruptions if dac0808 necessary. It seems that you are printing the text about the incomingByte all the main dac0808 iterations, I think this could be annoying and also takes processing capacity.

And the dac0808 we dac0808 a program in the wiring language. Veve 4, 5 24 Some things about your project For a wave generator it’s dac0808 a good idea to generate the signal in the main loop.

For sin wave and tangent wave I suggest to take a look at the casting of the variable float to int. Stack Overflow dac0808 best dsc0808 JavaScript enabled.
