New build.

[Christopher Kindig]

amazing, 2 days for me. 3 minutes for you.
I need to do some more learning thank you Fernando.

I found a missing part in setup:

Code: Select all

pwm.begin();
pwm.setPWMFreq(1600);

all wavemaker functions are working with ferduino and web control through PCA9685 board using I2c communication, next to build a menu for control of the return and protein skimmer pumps so they can all be put on the same power supply. yay less wall outlets used.

Hi!

I see this line but I think there a default value, so this line is not mandatory but I'm not sure.

Best regards.

Pump did not run without it so I added it and pumps were running.

If I am correct it is the communication to tell the PCA how fast to run in hertz frequency, I believe 1600 is the max speed that it will process.

[Fernando Garcia]

Yes, the library haven't a default value declared for frequency.

Hi Fernando I am working with theold board again and can not get the screen to come up I used this from a long time back and checked all pins
as shown, on the 20x2 all pins have a reading of 4.2 volts and on the others pins 6 and 7 have no voltage any thoughts?

update never mind it is okay now found a bad connection.

Hi!

Using the code below try:

1º Check if have ~ 4.5 V on pins 3 - 7, 22 - 41 and 50 - 53;

2º Check if have ~ 3.3 V in all pins else to GND and NC on connector 2 x 20.

Code: Select all

void setup()
{
  for(int i = 3; i < 8; i++)
  {
    pinMode(i, OUTPUT);
    digitalWrite(i, HIGH);
  }
  for(int i = 22; i < 42; i++)
  {
    pinMode(i, OUTPUT);
    digitalWrite(i, HIGH);
  }
  for(int i = 50; i < 54; i++)
  {
    pinMode(i, OUTPUT);
    digitalWrite(i, HIGH);
  }
}

void loop()
{
}


Best regards.
