void on_uart0_rx ( void  )

UART0 RX interrupt handler.

Here is the caller graph for this function:

◆ on_uart1_rx()

void on_uart1_rx ( void  )

UART1 RX interrupt handler.

Here is the caller graph for this function:

◆ pico_irq_ctrl_init()

int32_t pico_irq_ctrl_init ( struct no_os_irq_ctrl_desc **  desc,
const struct no_os_irq_init_param param
