Serial interrupt causes the TX to stop working after a while
- board: NUCLEO-F411RE
- IDE: https://developer.mbed.org/compiler/
- OS: Windows 7
- library: mbed.h
- serial used: UART 6
Intro: The code above is a stripped down version from a project I'm working on.
Problem: If the code inside the serialRxInterrupt function is commented out, the GPS and the board work perfectly together. The GPS goes into standby and wakes up correctly. If the code remains as is on the above link, the board stops sending TX signals on serial after a while. A screenshot from Saleae Logic: https://i.imgur.com/j5dVd4f.png
