we need some example code, like:

• py: assemble, load and run some ulp code (done, seeexamples/counter.py)
• py/asm: give data to / fetch data from ulp (done, seeexamples/counter.py)
• asm: ulp blink
• py/asm: implement framework for ULP data acquisition (collect data with ULP [while main CPU sleeps] into buffer, wake up main CPU, read/process buffer by main CPU, go to sleep again)

Maybe it is best to open a new ticket for each example we are working on.
