      Is this problem already solved?

      I encountered the same problem and found a solution.
      I think this is a mistake in the sample program.

      Although the variable `count' in the function i2c_on_transmit must be global it is interpreted as a local variable.

      I have modified the i2c_on_transmit() as follows.

      def i2c_on_transmit()
        global count
        count = count + 1
        print ("on_transmit, send:", count)
        return count
      

      Then, it worked well.
