I was trying to interface a BMP 180 with BLE Nano V2. To get started, I tried building the SW twi_master and then when I checked the ping config I realized that the pins are P0_2 and P0_28. I changed these numbers in the header file and tried flashing the code. My sensor was not identified.
I tried checking the SCL0 line on the CRO and I see that the lines arent even pulled up. I see that there are internal pull-ups on i2c lines but I do not see them in action. Am I missing something? Are the pins right?
