1.30. lpc17xx_wdt Module

Watchdog client library functions. Find implementation details in LPC17xx CMSIS-Compliant Standard Peripheral Firmware Driver Library documentation.

class robovero.lpc17xx_wdt.WDT_CLK_OPT

Clock source option for WDT.

  • WDT_CLKSRC_IRC0: Clock source from Internal RC oscillator
  • WDT_CLKSRC_PCLK: Selects the APB peripheral clock (PCLK
  • WDT_CLKSRC_RTC: Selects the RTC oscillator
WDT_CLKSRC_IRC = 0
WDT_CLKSRC_PCLK = 1
WDT_CLKSRC_RTC = 2
robovero.lpc17xx_wdt.WDT_ClrTimeOutFlag()

Clear WDT timeout flag.

robovero.lpc17xx_wdt.WDT_Feed()

After setting WDTEN, call this function to start Watchdog or reload the Watchdog timer.

robovero.lpc17xx_wdt.WDT_GetCurrentCount()

Get the current value of WDT.

Return:

  • current value of WDT
robovero.lpc17xx_wdt.WDT_Init(ClkSrc, WDTMode)

Initialize the Watchdog timer function.

Args:

  • ClkSrc: Select clock source, should be:
    • WDT_CLKSRC_IRC: Clock source from Internal RC oscillator
    • WDT_CLKSRC_PCLK: Selects the APB peripheral clock (PCLK)
    • WDT_CLKSRC_RTC: Selects the RTC oscillator
  • WDTMode: WDT mode, should be:
    • WDT_MODE_INT_ONLY: Use WDT to generate interrupt only
    • WDT_MODE_RESET: Use WDT to generate interrupt and reset MCU
class robovero.lpc17xx_wdt.WDT_MODE_OPT

WDT operation mode.

  • WDT_MODE_INT_ONLY: Use WDT to generate interrupt only
  • WDT_MODE_RESET: Use WDT to generate interrupt and reset MCU
WDT_MODE_INT_ONLY = 0
WDT_MODE_RESET = 1
robovero.lpc17xx_wdt.WDT_ReadTimeOutFlag()

Read WDT timeout flag.

Return:

  • timeout flag status of WDT
robovero.lpc17xx_wdt.WDT_Start(TimeOut)

Start WDT activity with given timeout value.

Args:

  • TimeOut: WDT reset after timeout if it is not feed
robovero.lpc17xx_wdt.WDT_UpdateTimeOut(TimeOut)

Update WDT timeout value and feed.

Args:

  • TimeOut: timeout value to be updated
