티스토리 뷰
사실 주인장은 심각한 vfd중독이였습니다.
오죽하면 어디서 싸게 풀린 vfd의 구매를 반복하다가 쓰지도 못하는 vfd만 10개 넘게 있는 수준이였죠
그 vfd중에 한가지를 골라서 이번에 날 잡고 구동을 시켜봤습니다.
먼저 구동할 VFD입니다. 구입은 https://www.aitendo.com/product/19370.
해당 사이트에 데이터시트가 있으나 혹시 몰라 여기도 올려봅니다
GP1150A01A-Futaba.pdf
2.68MB
256x64 구성의 후타바 생산 vfd입니다
GP1150A01의 모델명이며 rs232를 사용합니다
후면 부분입니다. 90v의 상당히 높은 전압을 사용하고 있어서 취급에 주의 바랍니다.
핀맵입니다. 왼쪽부터 오른쪽 순으로 각각 1번과 2번은 RTS, CTS핀으로 서로 연결하거나 아두이노에 연결하면 되나 여기서는 그냥 서로 연결해뒀습니다.
그 다음 3번 핀은 음극으로 전원공급장치의 -단자에 연결합니다
다음 4번, 5번은 각각 RXD, TXD핀으로 데이터가 오고 가는 핀 입니다. 후술할 MAX232 칩을 거쳐 아두이노에 연결하면 됩니다
마지막 핀은 24v 입력 핀입니다.
max232칩 입니다. 대충 높은 전압의 신호를 아두이노가 알아들을수 있게 낮추거나 높혀주는 칩 입니다.
알리에서 대충 싼걸로 집어왔습니다
핀맵은 다음과 같습니다. 만약 구동이 안될시 vfd부분의 tx와 rx를 바꿔보세요
추가로 전원은 아두이노쪽의 접점에서 5v +-를 입력하고 VFD는 -쪽만 연결해주세요
대충 연결을 했다면 이제 코드를 넣어봅시다.
먼저 가장 기본적인 텍스트를 띄우는 코드입니다.
업로드 전에 아두이노와 max232의 신호선 둘중 하나를 땐 뒤 업로드를 하셔야 오류가 나지 않습니다.
void setup() {
// 9600 baud, 8 data bits, ODD parity, 1 stop bit로 시리얼 초기화
Serial.begin(9600, SERIAL_8O1);
delay(1000); // VFD 부팅 대기
// 화면 초기화 (Clear display) 명령어 전송: 1BH 5BH 32H 4AH [cite: 103]
Serial.write(0x1B);
Serial.write(0x5B);
Serial.write(0x32);
Serial.write(0x4A);
delay(100);
// 영문 테스트 문자열 출력
// 한글은 Shift-JIS 기반이므로 아두이노에서 바로 EUC-KR/UTF-8로 보내면 깨집니다.
Serial.print("Hello World!");
}
void loop() {
// 추가 동작 없음
}만약 정상적으로 진행이 되었다면 다음과 같은 결과가 나올겁니다.
다음 코드는 이미지를 띄우는 코드입니다.
#include <avr/pgmspace.h>
// 1. 이미지의 가로, 세로 크기 설정 (반드시 이미지 크기와 일치해야 합니다)
const int imgW = 256;
const int imgH = 64;
// 2. image2cpp 웹사이트에서 변환한 16진수 데이터를 여기에 붙여넣으세요.
// (아래 데이터는 가로16x세로16 크기의 예시 데이터입니다)

}다음 코드는 0,0위치에서 256x64크기의 이미지가 출력되는 코드입니다.
먼저 흑백 이미지 적당한걸 준비합니다.
준비한 흑백 이미지를 해당 사이트에 넣기 전 https://ezgif.com/ 사이트를 활용해 vfd해상도에 맞게 자른뒤 준비해야 합니다.
이 모듈의 경우 256x64이니 그 해상도에 맞추면 되겠지요.
다음으로 이미지를 16진수 HEX로 변환을 해야 합니다. 변환 사이트는 다음 https://javl.github.io/image2cpp/를 이용하였습니다.
그리고 또, 이 VFD의 그래픽 모드는 세로 배열을 사용하므로 Vertical - 1 bit per pixel 모드를 사용해 변환합니다.
아무튼 이제 올바르게 넣고 작동을 시켰다면 다음과 같은 결과를 확인할수 있습니다.
마지막으로 진행할것은 애니메이션이며 DVD플레이어를 보면 로고가 화면 가장자리에 충돌시 방향을 전환하는것과 비슷하게 사각형이 화면 가장자리에 충돌시 방향이 바뀌게 하는 코드입니다.
// 사각형의 크기 (세로 8픽셀은 데이터 1바이트로 가득 찬 사각형이 됩니다)
const int boxW = 16;
const int boxH = 8;
// 초기 위치 및 속도 (픽셀 단위 이동)
int posX = 10;
int posY = 10;
int dirX = 3; // X축 이동 속도 및 방향
int dirY = 2; // Y축 이동 속도 및 방향
// VFD 화면 크기 (데이터시트 스펙: 256x64)
const int screenW = 256;
const int screenH = 64;
void setup() {

delay(100);
}
void loop() {
// 1. 이전 프레임의 사각형 지우기 (false를 전달하여 0x00 빈 데이터 전송)
drawBox(posX, posY, boxW, boxH, false);
// 2. 사각형 좌표 업데이트
posX += dirX;
posY += dirY;
// 3. 벽면 충돌 검사 (화면 경계에 닿으면 방향 반전)
if (posX <= 0 || posX + boxW >= screenW) {
dirX = -dirX;
posX = constrain(posX, 0, screenW - boxW);
}
if (posY <= 0 || posY + boxH >= screenH) {
dirY = -dirY;
posY = constrain(posY, 0, screenH - boxH);
}
// 4. 새로운 위치에 사각형 그리기 (true를 전달하여 0xFF 꽉 찬 픽셀 전송)
drawBox(posX, posY, boxW, boxH, true);
// 5. 애니메이션 속도 조절 (약 30 fps)
delay(30);
}
// VFD의 그래픽 디스플레이 모드(Graphic display mode)를 사용하는 함수

Serial.write(0x5C);
Serial.write(0x3F);
Serial.write(0x4C);

Serial.print(y); Serial.write(0x3B);
Serial.print(h); Serial.write(0x3B);
Serial.print(w); Serial.write(0x3B);
// 사각형 영역을 채우기 위해 전송해야 할 총 바이트 수 계산
int totalBytes = w * ((h + 7) / 8);
// fill이 true면 사각형을 그리고(0xFF), false면 그 자리를 지웁니다(0x00).
byte dataByte = fill ? 0xFF : 0x00;
// 데이터(Pd)를 VFD로 연속 전송
for (int i = 0; i < totalBytes; i++) {
Serial.write(dataByte);
}
}진행시 다음 링크와 같은 결과를 확인하실수 있을겁니다.

이 외에도 VFD가 몇개 더 있는데 이녀석들은 데이터시트가 아에 없는 물건이여서 구동이 가능할지 모르겠네요..
