Description
This example program demonstrates reading from a serial terminal, as described in Text Output and Input.
It uses one core only, and the kernel. There are two threads:
- thread 0: blink LED, to check if our terminal reading is blocking
- thread 1: read strings and integers from the terminal
Thread 1 runs two loops:
- read string: check buffer overflows, FIFO overruns
- read integer: check syntax and out of limits inputs
Entering an empty input switches between the two loops.
Experiment with different buffer sizes and baud-rates, see also Text Output and Input, section Design Considerations.

Set (PuTTY):
- Terminal: local echo and local line editing to
Force on
- Speed (baud): 38400
Build and Run
Build module ReadTerminal
with Astrobe, and create and upload the UF2 file using abin2uf2
.
Set Astrobe’s memory options as listed, and the library search path as explained.
