BCD to change digit - Githubissues

I have an old VFD that uses BCD to change the digit. I am not a coder, but butchered some code to sort of make it work. Could you add something to make it work more elegantly? At the moment it should present the number "4" in all 7 segments. As you can see, I did use your example in it. I have not physically tried it, but simulated it with LEDs to represent it on a Mega 2650. In the schematic, GRA-GRD are the BCD going to a 7442 BCD to 10 decimal IC. It may not be worth the time, but I felt it would be worth asking.

Thank you, Ed

}

void loop() { for (byte bit=0; bit<4; bit++) { if (bitRead(digit, bit) == 1) digitalWrite(digitSelectPin[bit], HIGH); } delay(d); for (byte bit=0; bit<4; bit++) { if (bitRead(digit, bit) == 1) digitalWrite(digitSelectPin[bit], LOW); } //delay(dm); //not sure why you would want this, it would make display dimmer and flickery? Keeping for the moment to keep with the OEM's signal timing

digit++; if (digit >= 6) digit = 0;

sevseg.setNumber(4); //Ed sevseg.refreshDisplay(); //Ed } `
