Ameba Amb23 I2c Ssd1306 Oled Display Not Work Technical Support Upon testing the compilation passes while using amb21 or 23. since i don’t have ssd1306 oled display, there are a few things that you could test with amb21, which is the board that is already working: note that set3 is i2c1, remember to update wire.begin () to wire1.begin (), etc during testing. To make necessary changes, follow the steps below: open “my computer” > documents > arduino > libraries > adafruit ssd1306. from the library folder, open adafruit ssd1306.h file. you need to uncomment the statement which defines the resolution of your display and comment all other statements.
I2c Oled Display Realtek Iot Wi Fi Mcu Solutions As the i2c address scanner does not work. looks like the arduino is not able to communicate with the display maybe? make sure a4 & a5 actually work. easy method is see if you can blink an led using those pins. However, the display refuses to turn on. the i2c connection seems fine, and there’s no error in the software. i tried both i2c addresses i found mentioned online which are 0x3c and 0x3d. my test implementation looks like the following. void setup() { serial.begin(115200); serial.println("initializing ssd1306 ");. Try making sure the display board is getting reset either "manually" using a digital output from the controller board, or by connecting to the mcu's reset. it would also help if you identified exactly what display board you have. I've tried 2 different codes, one that i made and one example from the ssd1306 library. there are no errors, the oleds just don't light up. the board is alco connected to 4 touch sensors i am using for the same project but they have nothing wrong with them (yet).

The i2c scanner sketch still detects the display at address 0x3c and display.begin (ssd1306 switchcapvcc, 0x3c) in one of the example sketches (adafruit ssd1306 library) returns true, indicating a successful startup of the display. If a your screen is not working, the first thing to do is use a multimeter and make sure that vcc=scl=sda=3.3v. (in the picture below my camera caught the screen refresh partially through…. Open the example in “file” > “examples” > “amebawire” > “oled ssd1306”. for this example, we will be using 0x3d as the address. if the address doesn’t work for you, you can run i2cscanner to find the oled address by navigating to “file” > “examples” > “amebawire” > “i2cscanner”. I have recently bought one of the 1.3'' oled, and no success using ssd1306. most of the lines were scrambled when i have tried to use my oled with this software driver. after some tinkering i found this display to be a different driver (not ssd1306) namely: sh1106. how i found it?.
