First...congratulations....my question Pin number 27/28 ?

Hello

Happy new year to your relatives, friends and yourself !!!!!

Will study your program as a Bible for I2C management..smile but true.... My question is about the pins 27/28 indicated in your program...I checked the datasheet of the NUCLEO-F401RE QFP64 and it doesn't fit, so please excuse me if i have misundestood. Do you have then a confirmation about the pin numbers that you are using for the SRF08, means SDA/SCL ?

Thanks a lot and HAPPY NEW YEAR again !!!!!

Vincent

Pin 27/28 are I2C pins on the lpc1768 platform which was probably used to test the library. Change the code to the appropriate pins for your F401 target platform and dont forget about the pull-up resistors.
