Function Documentation

◆ ADC_IRQHandler()

void ADC_IRQHandler ( void )

This function handles ADC Interrupt.

ADC interrupt handler. Called when an ADC conversion sequence completes or an analogue watchdog threshold is crossed.

Definition at line 235 of file stm32wlxx_it.c.

References hadc.

◆ BusFault_Handler()

void BusFault_Handler ( void )

This function handles Prefetch fault, memory access fault.

Bus Fault handler. Called on a precise or imprecise bus access error (AHB/APB fault).

Definition at line 118 of file stm32wlxx_it.c.

◆ DebugMon_Handler()

void DebugMon_Handler ( void )

This function handles Debug monitor.

Debug Monitor handler. Called when the debug monitor is active and a breakpoint or watchpoint fires.

Definition at line 161 of file stm32wlxx_it.c.

◆ DMA1_Channel1_IRQHandler()

void DMA1_Channel1_IRQHandler ( void )

This function handles DMA1 Channel 1 Interrupt.

DMA1 Channel 1 interrupt handler. Services DMA transfer-complete and error events for USART1 TX DMA.

Definition at line 221 of file stm32wlxx_it.c.

References hdma_usart1_tx.

◆ EXTI0_IRQHandler()

void EXTI0_IRQHandler ( void )

This function handles EXTI Line 0 Interrupt.

EXTI line 0 interrupt handler. Mapped to the NFC_INT pin (PA0 / NFC_INT_Pin). Fires when the ST25DV16KC NFC tag asserts its GPO line to signal a new Mailbox message or field-change event.

Definition at line 207 of file stm32wlxx_it.c.

References NFC_INT_Pin.

◆ HardFault_Handler()

void HardFault_Handler ( void )

This function handles Hard fault interrupt.

Hard Fault exception handler. Called on unrecoverable processor exceptions (bus fault, memory fault, undefined instruction, etc.). Calls Error_Handler() by default.

Definition at line 88 of file stm32wlxx_it.c.

◆ MemManage_Handler()

void MemManage_Handler ( void )

This function handles Memory management fault.

Memory Management Fault handler. Called when the MPU detects a memory access violation.

Definition at line 103 of file stm32wlxx_it.c.

◆ NMI_Handler()

void NMI_Handler ( void )

This function handles Non maskable interrupt.

Non-Maskable Interrupt handler. Called on critical hardware faults that cannot be masked.

Definition at line 73 of file stm32wlxx_it.c.

◆ PendSV_Handler()

void PendSV_Handler ( void )

This function handles Pendable request for system service.

PendSV handler. Used by the RTOS (if present) for context switching; triggered by software to initiate a pending supervisor call.

Definition at line 174 of file stm32wlxx_it.c.

◆ RTC_Alarm_IRQHandler()

void RTC_Alarm_IRQHandler ( void )

This function handles RTC Alarms (A and B) Interrupt.

RTC Alarm (A and B) interrupt handler. Called when RTC Alarm A or Alarm B expires. Used by the LoRaWAN timer subsystem (stm32_timer) to wake the device from STOP mode and drive the MAC duty-cycle engine.

Definition at line 263 of file stm32wlxx_it.c.

References hrtc.

◆ SUBGHZ_Radio_IRQHandler()

void SUBGHZ_Radio_IRQHandler ( void )

This function handles SUBGHZ Radio Interrupt.

Sub-GHz radio (LoRa/FSK) global interrupt handler. Dispatched by the STM32WL interrupt controller for all radio events (TX done, RX done, CAD, timeout, etc.) and passed to the LoRaWAN stack via SubghzApp_RadioIrqProcessing().

Definition at line 280 of file stm32wlxx_it.c.

References hsubghz.

◆ SVC_Handler()

void SVC_Handler ( void )

This function handles System service call via SWI instruction.

Supervisor Call handler. Entry point for OS system calls via the SVC instruction.

Definition at line 148 of file stm32wlxx_it.c.

◆ SysTick_Handler()

void SysTick_Handler ( void )

This function handles System tick timer.

SysTick interrupt handler. Called every 1 ms by the HAL timebase and increments uwTick.

Definition at line 187 of file stm32wlxx_it.c.

◆ UsageFault_Handler()

void UsageFault_Handler ( void )

This function handles Undefined instruction or illegal state.

Usage Fault handler. Called on undefined instruction, unaligned access, or divide-by-zero.

Definition at line 133 of file stm32wlxx_it.c.

◆ USART1_IRQHandler()

void USART1_IRQHandler ( void )

This function handles USART1 Interrupt.

USART1 global interrupt handler. Called on USART1 RX data-register-not-empty, TX empty, and error events. Drives the character-by-character receive logic for the debug/command UART.

Definition at line 249 of file stm32wlxx_it.c.
