Vorago UART Bugfixes and functions to disable and enable interrupts

Merged Robin Mueller requested to merge mueller/vorago-uart-bugfixes into develop

  • Add functions to enable or disable interrupts. Important for critical sections when there is no RTOS present

  • Some important fixes in the Vorago UART interrupt handler and some minor tweaks

  • The interrupt handler was not able to process a simple string "Hello World!\n\r" received each 5 seconds. This was fixed by the following chages:

    1. RX status register is re-read after reading data from the FIFO because it might have changed (e.g. timeout has occured)
    2. If a timeout has occured, the remaining data in the FIFO is read

  • I tested these changes with the aforementioned string and a larger string which exceeds the FIFO size (about 40 bytes size) and I was able to receive those properly

  • Adds option to disable or enable the periodic printout from the test task, which can be set from configuration file with VOR_TEST_TASK_PERIODIC_OUTPUT

  • The issue might also be related to the use of the RS485 transceiver. I have not tested communication without the transceiver (at least thats a long time ago). But communication via RS485 is our use-case anyway
