Driver sure electronics [SOLVED]

[Pascal Petiot]

hello Fernando
I just installed my lighting, and am having a problem on my driver .
I have an unbearable whistle.
I tried another program the ACKduino and when I change the SetPinFrequency has 20000Hz hiss disappears .

Code: Select all

    RetCode = SetPinFrequency(Eclairage1, 20000);
    if (RetCode == false ) {Serial.println("SetPinFrequency Eclairage1 =fasle" ); }
    RetCode = SetPinFrequency(Eclairage2, 20000);
    if (RetCode == false ) {Serial.println("SetPinFrequency Eclairage2 =fasle" ); }
    RetCode = SetPinFrequency(Eclairage3, 20000);
    if (RetCode == false ) {Serial.println("SetPinFrequency Eclairage3 =fasle" ); }
    RetCode = SetPinFrequency(Eclairage4, 20000);
    if (RetCode == false ) {Serial.println("SetPinFrequency Eclairage4 =fasle" ); }
    RetCode = SetPinFrequency(Eclairage5, 20000);
    if (RetCode == false ) {Serial.println("SetPinFrequency Eclairage5 =fasle" ); }
    RetCode = SetPinFrequency(MoonPin, 20000);
    if (RetCode == false ) {Serial.println("SetPinFrequency MoonPin =fasle" ); }

is it possible to change this frecance in your program?

thank you for your help

Hi!

I don't know the divisor for 20 KHz but, try this method:

Arduino mega pins and hardware Timers

Pin Timer
46 OC5A
45 OC5B
44 OC5C
13 OC0A //Caution: this one directly effects major timing { i.e delay and millis}
12 OC1B
11 OC1A
10 OC2A
9 OC2B
8 OC4C
7 OC4B
6 OC4A
5 OC3A
4 OC0B //Caution: this one directly effects major timing { i.e delay and millis}
3 OC3C
2 OC3B

All that is really important above is the numbers. They tell you what timers there on.
For example pin 2 is OC3B which is timer 3.

another way to look at this is:
timer 0 —– pin 4, 13
timer 1 —– pin 11, 12, 13
timer 2 —– pin 9, 10
timer 3 —– pin 2, 3, 5
timer 4 —– pin 6, 7, 8
timer 5 —– pin 44, 45, 46

————————————————————————————–

TIMER 0 (Pin 4, 13)
Value Divisor Frequency
0×01 1 62.5035 KHz
0×02 8 7.8125 KHz
0×03 64 976.5 Hz // default
0×04 256 244.1 Hz
0×05 1024 61.0 Hz
Code: TCCR0B = (TCCR0B & 0xF8) | value ;

TIMER 2 (Pin 9, 10)
Value Divisor Frequency

0×07 1024 30.63 hz
Code: TCCR2B = (TCCR2B & 0xF8) | value ;
—————————————————————————————-

Timers 3, 4, 5 Oddly do not use the divisors the data sheet says: Below are actual measured values!

TIMER 3 ( Pin 2, 3, 5)
Value Divisor Frequency
0×01 1 31.374 KHz
0×02 8 3.921 Khz
0×03 64 490.1 Hz // default

0×05 1024 30.63 Hz
Code: TCCR4B = (TCCR4B & 0xF8) | value ;

TIMER 5 (Pin 44, 45, 46)
Value Divisor Frequency
0×01 1 31.374 KHz
0×02 8 3.921 Khz
0×03 64 490.1 Hz // default

0×05 1024 30.63 Hz
Code: TCCR5B = (TCCR5B & 0xF8) | value ;

To set your timer just add it to your sketch:
Here’s and example for Pins 9 and 10 on Timer 2 @ 490.1Hz;

void setup () {
TCCR2B = (TCCR2B & 0xF8) | 0×04;
}

Best regards.

I have a problem to post this message ignore it please.

[Pascal Petiot]

.thank you for your answer
but in which file I can find that.
because it exceeds but skills.

[Fernando Garcia]

Before ask you need try understand my answer.

This is not clear for you?

Code: Select all

void setup () {
TCCR2B = (TCCR2B & 0xF8) | 0×04;
}


[Pascal Petiot]

hello Fernando
thank you to bend you to my brobleme
I understand that I must write this am , to change the pin 9 and 10 for a frequency balance 64 490.1 Hz

Code: Select all

void setup () {
TCCR2B = (TCCR2B & 0xF8) | 0×04;
}

I do not understand is how I should change place or write ( in libraries, in ferduino code file ... )
I would like to avoid making a big stupidity and everything explode

To set your timer just add it to your sketch:
Here’s and example for Pins 9 and 10 on Timer 2 @ 490.1Hz;

thank you for your help .

[Fernando Garcia]

Put in the tab setup.

[Pascal Petiot]

I'm really sorry but trying several places in the file I have the following errors.

Code: Select all

setup : 4 error: stray '\' in program
setup.ino: in function 'void setup()'
setup:4: error: expected ';' before 'u00d704

sorry I have not seen the < .
I deleted it is the programming that compiles .
I test tonight and I inform you.

[Pascal Petiot]

hi Fernando .
problem solved . : -bd
the driver no longer any noise.
a big thank you . ^ : ) ^
remains only a sd card problem , I dig on the site.
