General • Re: RP2350B Pico-PIO-USB abnormality

This could be a catch with PIO pin mapping on RP2350B up to GPIO47:

Check PIO: GPIOBASE Register

https://github.com/sekigon-gonnoc/Pico- ... /pio_usb.c

Code:

#if defined(PICO_PIO_USE_GPIO_BASE) && PICO_PIO_USE_GPIO_BASE+0  if (highest_pin > 32) {    pio_set_gpio_base(pp->pio_usb_tx, 16);    pio_set_gpio_base(pp->pio_usb_rx, 16);  }#else  (void)highest_pin;#endif

I used GPIO28 and 29 pins, which are not greater than 32. So I think if the program can run on RP2350A, it can also run on RP2350B without any modification.
