Hello Ben,
I didn't find any example about SSD1306-I2C in FC9 with ESP32.
This program in IDE Arduino works perfectly :
#include <SPI.h>
#include <Wire.h>
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
#define OLED_RESET -1 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);
void setup() {
Serial.begin(9600);
Wire.setClock(400000);
Wire.begin();
// SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally
if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
Serial.println(F("SSD1306 allocation failed")); }
display.clearDisplay();
display.setTextSize(1); // Normal 1:1 pixel scale
display.setTextColor(SSD1306_WHITE); // Draw white text
display.cp437(true); // Use full 256 char 'Code Page 437' font
display.clearDisplay();
display.setCursor(0,0);
display.println(F("Status:Free"));
display.display();
}
void loop() {
}
My OLED1306.fcfx example program don't work.
Maybe the I2C pins assignment.
Thank you for your help.
