Multplie Timers

[Sunil vignesh]

Hi,

I need some clarification about how to create multiple Timer functions?

my application is to

1. read the VDD supply for every 10 sec

2. after BLE connected to mobile phone rssi value read for every 5 sec

3. need to read the sensor data for every 2 sec

and also i need to differentiate single button function like single press, double press and long press

I am using nRF52832 SDK15.3 in segger embedded studio .

Is there any predefined code for multiple Timer functions?

Hi.

I suggest you take a look at the Application Timer Tutorial, and also look at the examples \examples\peripheral\timer and \examples\peripheral\simple_timer where different configurations of the timer is demonstrated.

Best regards,

Andreas

HI,

I havee seen the two programs .

One with app_timer

another is nrf_drv_timer

is there any major difference between these two? . Is it work with LFCLK ?

I want to differentiate single press and long press to get system : Wakeup and Sleep mode.

how to use app_timer to detect long press

Hi.

The app_timer uses the RTC peripheral and the nrf_drv_timer uses the TIMER peripheral.

The RTC peripheral uses the LFCLK (32.768 kHz), while the timer peripheral uses the HFCLK.

 You have to configure it so that it fires on a long or a regular button press.

typedef struct
{
    bsp_event_t push_event;      /**< The event to fire on regular button press. */
    bsp_event_t long_push_event; /**< The event to fire on long button press. */
    bsp_event_t release_event;   /**< The event to fire on button release. */
} bsp_button_event_cfg_t;

Best regards,

as per ble_app_uart

uses BSP_BLE_ module  link .  here

as it is but i need is

current status         button          action              event

connected                 1              long push            BSP_EVENT_SLEEP

not connected          1              long push            BSP_EVENT_SLEEP

sleep                         1              long push            BSP_EVENT_WAKEUP

shall we change it like this???

I developed one hardware with 32MHZ clock . is it possible app_timer to be work on (32Mhz)
