Hi guys,
I'm looking at using a 5" TFT LCD for a project im working on (which also requires and RTC) and im noticing they both require access to the SCL and SDA pins for the i2c connection.
I was wondering if there was a way around this as i have read a few cases of the RTC data influencing the LCD screen when connected together.
I appreciate your help in advance!
No, there is no conflict in using SCL and SDA for several I/O.
That is the way to use a communication bus.
Check thst the bus listening devices have differemt afdtrddrd.
I have used a couple different I2C RTC units along with I2C LCDs and never had a bit of trouble. Point us to the places that said that you would have trouble. I, for one, would like to see them.

Sounds like a misunderstanding.
Normally people write the RTC data to the LCD.
