1.8 OLED 160x128 Color-Display show always Config-Line

Posted at:2016-07-16 08:27:02 Edited at:2016-07-16 18:40:11

I have a 1.8 OLED color display 160128 v3.4. I connect the display with SPI (8,9,10). SPI mode always displays mode 0 and can not change. The display always starts white-red-green-blue with a fullscreen color change. Then the config line is displayed. I can not turn off the ConfigData. The command 'mydisp.displayConfig (0);' has no effect. Similarly, the command 'mydisp.displayStartScreen (1) or (0);' has no effect. My program will start after approximately 20 seconds. What can I do to start the program immediately?

	Try to run our sample code, if the sample code working, please check the setting and initilization in your code.

The sample code works, but only after a few Skunden. Setting and Initialisation is correct, yes has previously also worked well. I've written several programs for the display. The effect has occurred suddenly.

#define _Digole_Serial_SPI_

#define Ver 34 //if the version of firmware on display is V3.3 and newer, use this

#include <DigoleSerial.h>

//--------SPI setup

#if defined(_Digole_Serial_SPI_)

DigoleSerialDisp mydisp(8,9,10); //SPI:Pin 8: data, 9:clock, 10: SS, you can assign 255 to SS, and hard ground SS pin on module

#endif

void setup() {

mydisp.begin(); //initiate serial display port

delay(300);

mydisp.setSPIMode(0); //set SPI mode in V3.4, the available mode are 0,1,2,3

mydisp.setBgColor(0); //set another back ground color

mydisp.displayStartScreen(0); //disable StartScreen

mydisp.displayConfig(0); //disable ConfigScreen

mydisp.setMode('C');

}

	The sketch looks good, you only need to run "displayStartScreen(0);" and "displayConfig(0);" one time, the moudle will remember these config, and it will not show the welcome screen and config on next power on.

	I have the two lines already uncommented. The config line is still displayed.

	Could you try UART or I2C mode? there may be some timing issue with SPI on your application.

	To test it would be possible. But not in my project. UART is occupied by a GPS module and I2C by an RTC module.

	juhuuu, I now have all switched to i2c. The first sketch upload I said two lines enabled. The second upload with deactivated lines it worked. BINGO. Thanks for the hint.
