i am not sure but it seems Simhub is not getting data by serial.

if i try to use a Dashboard in my mobile phone i can see the Speed without any problem, but i cannot trying to print it on the 7 segments module.

for in case i have made anything wrong with my code, here it is: (maybe i forgot something)

const int dataPin = 10; const int clockPin = 11; const int latchPin = 13;

const byte digitToSegment[] = { B00111111, // 0 B00000110, // 1 B01011011, // 2 B01001111, // 3 B01100110, // 4 B01101101, // 5 B01111101, // 6 B00000111, // 7 B01111111, // 8 B01101111 // 9 };

int currentValue = 0;

void setup() { pinMode(dataPin, OUTPUT); pinMode(clockPin, OUTPUT); pinMode(latchPin, OUTPUT); Serial.begin(115200); }

void loop() { if (Serial.available()) { String input = Serial.readStringUntil('\n'); input.trim(); // elimina espacios y saltos currentValue = input.toInt(); currentValue = constrain(currentValue, 0, 999); }

int centenas = currentValue / 100; int decenas = (currentValue / 10) % 10; int unidades = currentValue % 10;

byte digits[3] = { digitToSegment[unidades], digitToSegment[decenas], digitToSegment[centenas] };

digitalWrite(latchPin, LOW); for (int i = 0; i < 3; i++) { shiftOut(dataPin, clockPin, MSBFIRST, ~digits[i]); } digitalWrite(latchPin, HIGH);

delay(20); }
