declaration in setup() possible?

[tobiasfaust]

Hi, global declaration of display works with SSD1306Wire display(0x3c, D3, D5); But i need the declaration of i2C Pins and i2cAddress inside of setup() because all user-defined parameters has to load from SPIFFS before. Has anyone a hint for me to solve this?

self solved ;)

#include "SSD1306Wire.h"

SSD1306Wire* ssd;

void oled_setup() {
  // Read parameters previously from SPIFFS via getParameters procedure
  Serial.print("Starting OLED 1306: (");
  Serial.print(i2caddress_oled);
  Serial.print(", ");Serial.print(pin_sda);
  Serial.print(", ");Serial.print(pin_scl);
  Serial.println(")");

  ssd = new SSD1306Wire(i2caddress_oled, pin_sda, pin_scl);
  ssd->init();

  ssd->flipScreenVertically();
  ssd->setFont(ArialMT_Plain_24);
}

void oled_loop() {
  // clear the display
  ssd->clear();
  // draw the percentage as String
  ssd->setTextAlignment(TEXT_ALIGN_CENTER);
  ssd->drawString(64, 15, String(hcsr04_level) + "%"); 
  // write the buffer to the display
  ssd->display();
}
