I can not make long-distance data transmission by making the system master / slave with I2C.
I have ADCs that have a certain adrese. He works on short distances.
Even when I pulled up, I could work at 5 meters.
I need to support me at least 30 meters.
I2C bus buffer / repeater samples (PCA9515, PCA9511, PCA9517, etc.) I searched but could not find the market in Turkey. It will take too long to wait.
Alternatively, which way do I have to follow and what method can I do?
Thanks for your help.
