MCP4725 ardunio

HELLO THERE
I want to control two mcp4725 dac with arduino

I could not find a sample project that works with two addresses and gives analog 0-5 outputs.

Let's try to write an example code with two addresses.

to a rookie like me
Can you help me ????

The the last bit( LSB ' 'L), sent following the address bits, is ignored as it is the read write bit (R/Wn). Therefore the addresses with only A0 available as an address control are:
0x60, 0x61
For each device you can set A0 to one or zero. The rest (A1 and A2) are specified on purchase.

Pardon

Excuse me
Site has been renewed

I have no idea what you mean

Do you have a comment or maybe a question ?

Try something like this.
in setup()
dac1.begin(0x60); // add pin grounded
dac2.begin(0x61); // add pin to vcc
Then use dac1 and dac2 throughout your code.
Leo..

Okay, I got it
I'll write an example, I'll share the code

I will share a sample picture

I am using normal mcp4725

I don't use it, wrong
is an excerpt

We may have a language problem here

@nzmxp what is your native language ?

Turkish language

I need to pay attention to the translations
google translation language

OK. I was hoping that there would be a suitable International section of the forum where you could interact more easily, but there isn't

thanks for the warning
,,, UKHeliBob ,,,

I sent questions. Does anyone want to answer?
Of course, we have an understandable common language, even if there is no full translation. !!!

Hi,
Welcome to the forum.

Have you programmed an Arduino before?
Are you familiar with C++ language?
What hardware do you have?

We need a answer so we know where to start helping you with your coding.

Thanks.. Tom... :grinning: :+1: :coffee: :australia:

hello TomGeorge

I'm new to Arduino, amateur I haven't made software with c ++ in these languages I am someone who deals with electronic pcb repair

you have a very popular title of teacher
There are so many things we need to learn from you, as a newcomer to ardunio.I wanted you to help me. I have a question.

                  sensorValue = analogRead (rdtt2); // the input has been set for pwm if the value is entered:

rdtt2 = map (sensorValue, 0, 1023, 0, 255); // map out:

I want it to increase with a delay every 8 values by dividing the 8bit voltage that rises up to 0,255 in the sample code.

(0, 1023, 0,8, delay, 16, delay, 32, delay, 64, delay, 128, delay ........... more ........ .... up to ... 255);

My teacher, I tried to make it understandable. If you help me, can you share a code that can do this with the sample code.
thanks

I compiled the code, I compiled it without any problems. Are there any errors?
There are some additions that I would like to add to the code sample
0, 1023, 0, 8, militia ??? militia ... 255); 100 ms delay seems sufficient
I want to increase with delay when rising 0-5v
