Hi, I created some small examples for the C8051F***
https://github.com/merbanan/C8051F300_examples
I tried these examples on a F340 but something doesnt work correctly when
I send data over the serial port and sdcc. If I use Keil it works fine.
And the same code works fine on the F300.
I'd be happy to supply you with hardware if you are interested to
investigate the issue. Currently I use Keil which works with what I want
to do, but doing open stuff and needing a non free compiler causes an itch
I want to scratch.
