Hardware Serial Terminal
Posted: Fri May 27, 2016 8:35 am
Old meets new! This is a little circuit using a MAX3232 level converter to allow UART3 to talk to a DEC VT-510 hardware serial terminal.
The schematic is right off the data sheet. See it in action: https://youtu.be/Pb1bLqhhmes
To make the pyboard copy its REPL to this port, I added this line to boot.py:
pyb.repl_uart(pyb.UART(3,9600))
Also it means having the virtual COM port for the pyboard set up. Follow the instructions given here (http://micropython.org/resources/Micro- ... -setup.pdf) or just go to http://www.st.com and get the STM virtual COM port driver, search for part number STSW-STM32102. This is a signed driver so should make installation less painful for Windows 8/8.1
