Can Silabs be programmed on breadboards?

with todays fast rise/fall times you are going to get reflections all over the place and will end up spending more on aspirin than you save by not buying a devboard. If money is the issue buy a SILabs tolstick (< $20)

to answer your question
should you, by some miracle, get a breadboard to run ANY chip that can be programmed on a devboard can be programmed on a breadboard
