tomaskovacik / arduino Goto Github PK

Hey @tomaskovacik,

I'm dealing with your version of the myMatrix lib for some time now. I've come to the point where I want to controll a 4th display with the same arduino, meaning a display size of 128x16 pixels.
As far as I found out you only added the offset rountine to the original lib. I tried to add a new offset for x>95, but then my arduino restarts at calling myMatrix. I suppose this is due to an overflow at the uint8_t myindex. Is it possible to change this to unit16_t without problems?
Did you ever tried having a larger display, maybe with other code?

Regards,
Anduril

Hi tomaskovacik, do you think is posible to implement the 3LB protocol and comunicate whit instrument cluster using a Raspberry Pi and GPIO interfaces?

Using your code I've tried this: http://pastebin.com/Qg08ZqYr

But whitout success.

What do you think? Your work is awesome!!!

Thanks, Samuel.

Is there any documentation on how to work with this? I know that it works with arduino uno. But is there any tutorial you have for it? Can you make one?

https://www.arduino.cc/en/Hacking/libraryTutorial

documentation about library functions is required

like here, if posible

Hello,

congrats to your research i would like to ask your help because i stack in one point.
Based on your source code i write my own with 4 push button inputs .

`int OUTpin = 1;

int buttonUPpin = 2;
int UpinStatus=LOW;

int buttonDOWNpin = 3;
int DpinStatus=LOW;

int buttonVOLDpin = 4;
int VDpinStatus=LOW;

int buttonVOLUpin = 5;
int VUpinStatus=LOW;

int h=0x00;

void setup() {
// put your setup code here, to run once:

pinMode(OUTpin, OUTPUT);
pinMode(buttonUPpin, INPUT_PULLUP);
digitalWrite(buttonUPpin,HIGH);

pinMode(buttonDOWNpin, INPUT_PULLUP);
digitalWrite(buttonDOWNpin,HIGH);

pinMode(buttonVOLDpin, INPUT_PULLUP);
digitalWrite(buttonVOLDpin,HIGH);

pinMode(buttonVOLUpin, INPUT_PULLUP);
digitalWrite(buttonVOLUpin,HIGH);

}

void loop() {
// put your main code here, to run repeatedly:

UpinStatus=digitalRead(buttonUPpin);
DpinStatus=digitalRead(buttonDOWNpin);
VDpinStatus=digitalRead(buttonVOLDpin);
VUpinStatus=digitalRead(buttonVOLUpin);

if(LOW==UpinStatus)
{

sendByte(0xD0);

}else

if(LOW==DpinStatus)
{
sendByte(0x50);
}else

if(LOW==VDpinStatus)
{
sendByte(0x80);
}else

if(LOW==VUpinStatus)
{
sendByte(0x00);
}

}

void sendByte(int cislo) {

int c_cislo=0xFF-cislo;
int cmdStart[32]={0,1,0,0,0,0,0,1,1,1,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
for (int i = 23;i>=16;i-- ){
if (cislo%2 != 0) cmdStart[i]=1;
cislo = cislo/2;
}

for (int i = 31;i>=24;i-- ){
if (c_cislo%2 != 0) cmdStart[i]=1;
c_cislo = c_cislo/2;
}
digitalWrite(1,LOW);
delay(9);
digitalWrite(1,HIGH);
delayMicroseconds(4500);

for (int i=0;i<32;i++){
Serial.print(cmdStart[i]);
Serial.print(",");
digitalWrite(1,LOW);

delayMicroseconds(600);
digitalWrite(1,HIGH);

if (cmdStart[i]==0)
  delayMicroseconds(600);
if (cmdStart[i]==1)
  delayMicroseconds(1700);

}

Serial.println("");
digitalWrite(1,LOW);
delayMicroseconds(600);
digitalWrite(1,HIGH);

}
`

The problem is when i check with serial monitor i can see only "ŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕŕ" for each button.When i connected to the remote controller of my radio it does not happened anything.What can be wrong with my code?

Not yet fully supported? Thanks
