SSD1327 over I2C not working

Sun Jul 05, 2020 5:24 pm

Dear fellow Raspberry PI users,

I have build a cocktail machine and everything was working fine. Because my mother in law complained about the size of the screen, I decided to upgrade the screen to a 1,5 inch SSD1327: https://www.tinytronics.nl/shop/nl/disp ... ls-wit-i2c.

The problem now is, I cannot get the screen to work, in terms of it does not even show up in the Raspberry PI I2C list ("sudo i2cdetect -y 1").
What I tried is:

1. Change the screen with another screen (I ordered three)
Result: not working
2. Tried to change the cables
Result: not working
3. Tried a different type of screen (0,96 inch SSD1306 OLED)
Result: works and appears in i2cdetect
4. Connected the screen with an Arduino uno
Result: works

I don't know what I can do more, the screen is connected with following RPI pins:
VCC => 5V (pin nr. 2)
GND => GND (pin nr. 9)
SDA => GPIO 2 / (pin nr. 3)
SCL => GPIO 3 / (pin nr. 5)

Hopefully someone can help me and knows what I did wrong or what I missed :).

Yours faithfully,

Lars Groot

Try to connect VCC at 3.3V.

Upgrade your mother in law.
