*What I have:*
- I have a 4-bit logic level converter.
- I have a BeagleBone Black running ubuntu, not angstrom. (BBB)
- I am using the PyBBIO library for serial communication on the BBB.
- I have the Device Tree Overlay
- I have an Arduino Uno.
*What I can/cannot do:*
- I am able to send from the Arduino to the BBB.
- When I attempt to send from the BBB to the Arduino I cannot.
- I am able to send from an Tx pin on the BBB to an Rx pin on the BBB.
- This is over a wire connecting the two together.
- I have also checked the output of the Tx pin with an Oscilloscope
and it is correct.
- This is true on both sides of the logic level converter.
- I cannot send from the Arduino Rx pin from the Arduino Tx pin.
- This again is over a wire.
- I do not have the USB plugged in.
*What I think:*
- I think I'm having some sort of problem on my Arduino.
- I have the 'L' LED blinking in my test program and eventually this
stops.
- I believe the program is eventually crashing but I am unsure why.
I was wondering if someone had any insight to what my problem could be? I
am not sure what is happening and I can post any code segments if they
would be beneficial.
Thanks!
