ILI9486 is down when i connect any sensor to SCL and SDA pins

[marius_groza]

Hello,

i am trying to make a project for which i am using an 3.5 inch shield display. For this i am using LCDWIKI libraries and is working fine, but when i want to connect another sensor to my Arduino Uno R3 on SCL and SDA pin the display became blank. This is happen when the pin SCL is connected.

Could you please help me to find out how to solve this issue?

Thank you

L.E. here are some pictures

have a read of how-to-get-the-best-out-of-this-forum
in particular

1. give details of display? e.g. link if possible
2. what is the host microcontroller? e.g. give a link
3. post the code - select < CODE/ > and paste the code or text where it says “type or paste code here”
4. how have you connected the modules? e.g. GPIO pins used

That type display typically uses A4 for the display RESET pin, so any use of the I2C bus resets the display.
What I've done is bend the RESET pin out to the side, and connect it through a 10K resistor to the UNO reset pin, so that the display is reset along with the UNO. The only time most display libraries use RESET is when the display is initialized by calling begin().

It works, thank you!
