# HW-364A (USB-C) / HW-364B (Micro USB)
- The HW-364A / HW-364B is a very practical and cheap ESP8266 with 0.96 Inch OLED Display.
- It is sold on all known platforms.
- Some dealers provide incorrect technical data, which sometimes makes it difficult to get it up and running...
- be aware that SDA and SCL may be swapped!!!
## Technical specs
- SDA is D6 / GPIO14
- SCL is D5 / GPIO12
- Address is 0x3C
## Code using Adafruit_SSD1306
```
#include
#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
#define OLED_RESET -1 // Reset pin # (or -1 if sharing Arduino reset pin)
#define SCREEN_ADDRESS 0x3C // If not work please scan the bus
#define OLED_SDA 14 // D6
#define OLED_SCL 12 // D5
Adafruit_SSD1306 *display;
int c = 0;
void handle_oled(int c) {
display->clearDisplay();
display->setTextSize(1);
display->setTextColor(SSD1306_WHITE);
display->setCursor(0, 0);
display->println("Display is working!");
display->println("");
display->println("");
display->println("Have fun with it");
display->println("");
display->println("");
display->print("Uptime: ");
display->print(c);
display->println("s");
display->display();
}
void setup() {
display = new Adafruit_SSD1306(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
Wire.begin(OLED_SDA, OLED_SCL);
display->begin(SSD1306_SWITCHCAPVCC, SCREEN_ADDRESS);
}
void loop() {
handle_oled(c);
c++;
delay(1000);
}
```
## Code using U8g2
```
#include
#define OLED_RESET U8X8_PIN_NONE // Reset pin
#define OLED_SDA 14 // D6
#define OLED_SCL 12 // D5
U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, OLED_RESET, OLED_SCL, OLED_SDA);
int c = 0;
void handle_oled(int c) {
u8g2.clearBuffer();
u8g2.setFont(u8g2_font_ncenB08_tr);
u8g2.drawStr(0, 10, "Display is working!");
u8g2.drawStr(0, 30, "Have fun with it");
char buffer[20];
snprintf(buffer, sizeof(buffer), "Uptime: %ds", c);
u8g2.drawStr(0, 50, buffer);
u8g2.sendBuffer();
}
void setup() {
u8g2.begin();
}
void loop() {
handle_oled(c);
c++;
delay(1000);
}
```
