S34358-02 VFD Display

Other Hardware Displays

Ok I have a S34358-02 VFD that was made by IEE. I have a pdf file that IEE sent me for this but I am hung up on how to connect this to an arduino uno so it can display sensor data like voltage off a voltage divider on an analog pin or temperature from a DHT sensor for example. I just need to know what library to use and how to connect this display.

The PDF file for the display is here:

Thanks.

Update! I managed to figure it out pins 2,4 are +5 VDCpins 6, 10 are ground and pin 14 is serial in. baud rate set to 9600 and Serial set to TTL. connect pin 14 to the arduino pin 1 TX. The arduino code I used to test with is such:
void setup() {
// Initialize serial communication
Serial.begin(9600); // Try different baud rates if needed (1200, 2400, 4800, 19200)
delay(100);

// Initialize display
initDisplay();
}

void loop() {
// Example: count from 0 to 999999
for(long i = 0; i <= 999; i++) {
displayNumber(i);
delay(1000);
}
}

void initDisplay() {
// Clear display
Serial.write(0x0C); // Form feed/clear
delay(1000);
}

void displayNumber(long number) {
char buffer[7];
// Convert number to string with leading zeros
sprintf(buffer, " %01ld ", number);
// Send to display
Serial.println(buffer);
}

// Function to position cursor
void setCursor(byte position) {
if(position < 6) {
Serial.write(0x1B); // Escape
Serial.write(position + 0x20); // Position + offset
}
}

// Function to clear display
void clearDisplay() {
Serial.write(0x0C);
}

// Function to set brightness (if supported)
void setBrightness(byte level) {
Serial.write(0x1B); // Escape
Serial.write(0x60 + (level & 0x07)); // Brightness command
}

That code counts up from 0 to 999

Before you can consider connections, you need to decide if you are going to use a serial data connection or a parallel data connection.
