pio_remove_program_and_unclaim_sm() function

PIO program to remove from memory

PIO hardware instance being used

PIO state machine that was claimed

offset of the program in PIO memory \see pio_claim_free_sm_and_add_program

Attempt to load the program \see pio_can_add_program() if you need to check whether the program can be loaded

Determine whether the given program can (at the time of the call) be loaded onto the PIO instance

Remove a program from a PIO instance's instruction memory

Finds a PIO and statemachine and adds a program into PIO memory

Finds a PIO and statemachine and adds a program into PIO memory This variation of pio_claim_free_sm_and_add_program is useful on RP2350 QFN80 where the "GPIO Base" must be set per PIO instance to either address the 32 GPIOs (0->31) or the 32 GPIOS (16-47). No single PIO instance can interact with both pins 0->15 or 32->47 at the same time. This method takes additional information about the GPIO pins needed (via gpi_base and gpio_count), and optionally will set the GPIO base (\see pio_set_gpio_base) of an unused PIO instance if necessary

Determine whether the given program can (at the time of the call) be loaded onto the PIO instance starting at a particular location

Attempt to load the program at the specified instruction memory offset \see pio_can_add_program_at_offset() if you need to check whether the program can be loaded
