Read keycode

This is not issue but a new feature. TM1650 has also a key scan of the digits 1-4 connected to segments A-G with a 2k resistor. The code can be retrieved by reading from address 0x24, control port. When there is valid code bits 2 and 6 are set. The codes are listed in the TM1650 manual. I checked this with 4-digit bought from ebay. Please add the code in your repository. It seems to be the one what people are browsing.

I have actually never been able to find a tm1650 manual, so the entire library was built by trial an error. Do you mind sharing it with me? arkhipenko@hotmail.com

Since I don't have the manual, I am not sure what key scan functionality you are referring to... Happy to add to the library once I understand what it is.

I found it on the manufacture’s site http://www.titanmic.com/e_products/TM1650-2-25.html unfortunately it is china, but fortunately we have google translate.

The code is here

int TM1650::keycode() { byte x; Wire.requestFrom(TM1650_DCTRL_BASE,1,true); // x = Wire.read(); return x&0x40?x:0; // returns 0 if no key pressed

}

I also added to my version displayInt, because this is digit display

int TM1650::displayInt(int aI) { int i; char neg=0; if(aI>9999){ displayString("+Err"); return 1; } if(aI<-999){ displayString("-Err"); return -1; } if(aI<0){ aI=-aI; neg=1; } for(i=3;i>=0;i--){ setPosition(i,aI?pgm_read_byte_near(TM1650_CDigits + aI%10+'0'):(i==3?0x3f:0));aI/=10; if(neg) setPosition(0,64); } return 0;

}

I tried to add the mentioned code but it only run for on time then my loop don't work

I restarted the boar but this loop work only once if I remove the getKeycode function it works fine

and even I've edit the headers file to check it steams to stop workin after calling Wire.requestFrom(TM1650_DCTRL_BASE, 1, true); .

 #include <Wire.h>
#include <TM1650.h>

TM1650 d;

void setup() 
{
  Wire.begin(); //Join the bus as master

  Serial.begin(9600); //Start serial communication at 9600 for debug statements
  Serial.println("TM1650 Example Code");

  d.init();

}

void loop() 
{
  d.displayOff();
  d.displayString("Omar");
  d.setBrightness(TM1650_MIN_BRIGHT);
  d.displayOn();
  delay(100);
  char line[] = "Omar";
  int  key  ;

  delay(200);
  d.displayString("OLAL");
  delay(200);
Serial.println("Reading From keys");
key = d.getKeycode();
delay(200);

  }
