Help needed with RS232 comms

Recommended Posts

My first thought is that if your logic analyzer is showing the correct serial stream, it is the software on the computer that is going wrong. Have you played around a bit more with Realterm? It can be somewhat frustrating when using the LaunchPad's VCP. Make sure you have the right VCP selected, and make sure you make sure it's connected in Realterm. One good trick is to short the RX and TX pins on the LaunchPad together and make sure you can get the echo in your terminal. That would ensure that the software end is functioning correctly.

 

Hope you can get it working.
