It is a very old project. I will check it, give me some time and I report back to you.
I used an Arduino -pro-mini like this:
The pins used are 3, 4 and 5. Pins 3 (scl) and 4 (sda) are both pulled up by resistors of 4.7 k. Maybe you have forgotten to add these.
I also included a c++ version of the code. I'm not sure if this has been tested.
Ok , ill double check but I
m confused because wherever I check arduino pinouts I find references like this .
A4 and A5 are the standard I2C pins but i guess you are using D3 D4 and D5 . Is that ok?? that I didn`t test.
Yes, that's right pin 5 is the "hotplug"-pin. The I2C hardware is not used. It is software bit-banging.
hi there , sorry to bother you , I
m trying to use your sketch with an arduino nano and I can
t get it working . I saw at the ports declarations for i2c comm are 3 and 4 . Im really new at this so i was wondering if it
s not 4 and 5 pins . Anyways y tested both options with same result , when I connect it to my laptop i should see a new monitor detected i guess but no. Can you help me a little? thanks so much!!!!
