static void | check_hardware_alarm_num_param (__unused uint alarm_num) |
| |
| static uint32_t | time_us_32 (void) |
| | Return a 32 bit timestamp value in microsecondsReturns the low 32 bits of the hardware timer. More...
|
| |
| uint64_t | time_us_64 (void) |
| | Return the current 64 bit timestamp value in microsecondsReturns the full 64 bits of the hardware timer. The pico_time and other functions rely on the fact that this value monotonically increases from power up. As such it is expected that this value counts upwards and never wraps (we apologize for introducing a potential year 5851444 bug). More...

| void | busy_wait_ms (uint32_t delay_ms) |
| | Busy wait wasting cycles for the given number of milliseconds. More...

| void | busy_wait_until (absolute_time_t t) |
| | Busy wait wasting cycles until after the specified timestamp. More...
|
| |
| static bool | time_reached (absolute_time_t t) |
| | Check if the specified timestamp has been reached. More...

| void | hardware_alarm_claim (uint alarm_num) |
| | cooperatively claim the use of this hardware alarm_numThis method hard asserts if the hardware alarm is currently claimed. More...
|
| |
| int | hardware_alarm_claim_unused (bool required) |
| | cooperatively claim the use of this hardware alarm_numThis method attempts to claim an unused hardware alarm More...
|
| |
| void | hardware_alarm_unclaim (uint alarm_num) |
| | cooperatively release the claim on use of this hardware alarm_num More...
|
| |
| bool | hardware_alarm_is_claimed (uint alarm_num) |
| | Determine if a hardware alarm has been claimed. More...
|
| |
| void | hardware_alarm_set_callback (uint alarm_num, hardware_alarm_callback_t callback) |
| | Enable/Disable a callback for a hardware timer on this coreThis method enables/disables the alarm IRQ for the specified hardware alarm on the calling core, and set the specified callback to be associated with that alarm. More...
|
| |
| bool | hardware_alarm_set_target (uint alarm_num, absolute_time_t t) |
| | Set the current target for the specified hardware alarmThis will replace any existing target. More...
|
| |
| void | hardware_alarm_cancel (uint alarm_num) |
| | Cancel an existing target (if any) for a given hardware_alarm. More...
|
| |
| void | hardware_alarm_force_irq (uint alarm_num) |
| | Force and IRQ for a specific hardware alarmThis method will forcibly make sure the current alarm callback (if present) for the hardware alarm is called from an IRQ context after this call. If an actual callback is due at the same time then the callback may only be called once. More...
