[Swansea Hackspace] you have probably seen this

[Tim Moore]

I've just got the 28pin PIC32 which MicroMite.org use working.

This is the details (Linux fans only)

___
Now I used one of these USB to TTY converters:-
1P HOT SALE PL2303HX USB To RS232 TTL Auto Converter Adapter Controller
Module <http://www.ebay.co.uk/itm/111495072392>

which cost less than a quid delivered ,

If anyone is using Linux and gets to the CLI

and types

sudo apt-get install picocom

and once it has done that

types

picocom /dev/ttyusb0 -b 38400 -l   (now -l is really lowercase -L)

they can communicate with your brilliant PIC32 IC


to save the program and jump to the command mode control Q does the job

then RUN works and the code is saved.


To go back to the code type

Edit

_______________


Its all on page 10 of user manual Ver 4.5D

There are lots of red herrings hanging about such as minicom,


but that is the fix !
