It turns out that the sequence of adding the program and setting the GPIO base was the issue. I moved the GPIO base setting earlier, and everything started working.
2 functions in questionSomething weird is happening with detecting the GPIO ranges used in the PIO program in relation to the GPIO base. As I understand it, some checks need to be performed to determine which GPIO ranges are used in the PIO program and how they relate to the base settings.
Code:
PIO pio = pio2; uint sm = 0; pio_set_gpio_base(pio, 16); uint offset = pio_add_program(pio, &control_bus_program); pio_sm_config c = control_bus_program_get_default_config(offset); sm_config_set_in_pin_base(&c, 32);2 functions in question
Code:
static bool is_gpio_compatible(PIO pio, uint32_t used_gpio_ranges)static int pio_set_gpio_base_unsafe(PIO pio, uint gpio_base) Statistics: Posted by sh71rlic — Wed Nov 06, 2024 3:41 am
