Hello,
We are working on a customized TIVA board. The TIVA is connecting via ICE and Etherent , UART1 are working OK.
The attached code was created by PinMux utility in order to initialize I2C5,7
But when we sent data via I2C5 (and 7) we saw nothing with scope. No clock and no data
Can you tell what are we doing wrong ?
What should we check using scope or code ?
We used the same code on TI's TIVA board. In this board we used I2C6 only.
Best regards,
Z.V
