Some time is difficult to understand whether we have attached correctly a device to the I2C bus and what is the expected address for that device.
Mimic the same snippet made for Arduino I wrote this simple scanner which will tell what it can find on the I2C bus.
For simplicity I propose the software version which uses a bit-bashing.
The example works for all midrange MCU, tested a 16F877A and 12F675.
