I Want to use the I2c bus , In the Target h file I finde:

#define USE_I2C
#define USE_I2C_DEVICE_1
#define I2C_DEVICE (I2CDEV_1)
#define I2C1_SCL PB6
#define I2C1_SDA PB7

But I do not fine with pin is PB6 and PB7,?
Do someone knowe where I can finde the source for pin designation?

I was able to figure out the Smartaudio for the XSRF3E. I connected the SA wire to the T1 pin on UART1 and set UART1 in BF to Smartaudio. It seems pretty straightforward but all the info I've read said to connect to the TX on an open UART and according to the wiring diagrams I've seen the R1 pin is the TX on UART1.
