I2C address scanner - Scans I2C bus on specified pins and prints all addresses where a active responder is found.
Find address for I2C device
Scans all addreses on a I2C bus and reports those it is able to sucessfully communicate with.
One problem with I2C is that sometimes we receive chips without proper documentation and can not determine what address we should use ot communicate with that chip. This library seeks to identify the chips by attempting to communicate with each address and if it suceeds it assumes there is a chip present.
I have tested this with a clock chip, temperature sensor, OLED device and FRAM chip. It worked for all of them but there is a chance that some chips will not respond without a specific API call so there may be some chips it could not locate.
