Hello, I've been trying to get an OLED screen to work on my H7S3L8, but I've not been successful. I've followed this tutorial perfectly (as much as I could - there were things I couldn't do such as setting fast mode duty cycle as the option isn't there in CubeMX).
So far I've tried:
- Using 4.7k resistors between VCC and SDA/SCK (also tried without them)
- Only sending the command to turn all pixels on the screen on (0xA5 from the datasheet)
- Following different tutorials with example code to no avail
- Making sure there are no shorts and that the voltage is correct with my multimeter
I haven't yet had success. Does anybody have experience with the H7S3L8 or have an idea why this would not be working? The tutorial I linked at the top explicitly mentions that the code works on H7 families.
I only used this part of the above tutorial to display 2 words:
SSD1306_Init (); // initialise the display
SSD1306_GotoXY (10,10); // goto 10, 10
SSD1306_Puts ("HELLO", &Font_11x18, 1); // print Hello
SSD1306_GotoXY (10, 30);
SSD1306_Puts ("WORLD !!", &Font_11x18, 1);
SSD1306_UpdateScreen(); // update screen
while (1) { }
Side note - I know the screen works as it has been tested on an ESP32 using Espressif code.
Let me know if this is enough information, I'm happy to answer questions if it'll help!
