I am sending &amp; receiving data on UART1 &amp; UART2. Sometimes a character received on a UART causes an I2C transmission to fail. I tried disabling interrupts on the UARTs so that the processor would not be affected by the incomming UART data, but the problem still happens. To fix it I had to set the UART RX pin to GPIO. So it appears that the UARTs are directly interfereing with the I2C.
