Hello,
I'm having BIG trouble with a simple circuit
I want to use I2C with Arduino while connecting
LCD(0x27)
Oled(0x61)
RTC1307 (0x68)
INA219 (0x41)
all of them work on 5V
the connection is with a 4K7 pullups
when I conenct Oled + LCD - I can see them in the scan code
Scanning...
I2C device found at address 0x27 (39)
I2C device found at address 0x3D (61)
when I connec the RTC1307 - it get stuck \ or running for 3 more times (with out the resualt from the clock) then get stuck.
I have also try to connect INA219 - get stuck
what could be the problem ?
I have double check the wiring 10 times -- all good there.
when I only connect one (INA219 \RTC) - I can see it's working
Scanning...
I2C device found at address 0x40 (64)
maybe when a device is "sending" data - like the DS1307\INA219I need to use another circuit?
can't use both on the same bus?
Thanks,
