Any way to do some debugging on the little 56 pin version ?
Unfortunately, UARTs are available only on bigger cases.
I really like the 56 pin, QFN package.
Did Keil release source code for their monitor MON51 ?
We could tweak that to connect to an external, I2C uart.
How do other people do ?
Now, developing 16 Kb of code completely "blind", with just some pins I/O, and trial and error... there has to be a better way.
