# TIMER counter {#timer_counter}
|
||||||
|
|
||||||
|
The sample demonstrates a basic functionality of the nrfx_timer driver in Timer and Counter modes.
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
The sample supports the following development kits:
|
||||||
|
|
||||||
|
| **Board** | **Support** |
|
||||||
|
|---------------------|:-----------:|
|
||||||
|
| nrf52dk_nrf52832 | Yes |
|
||||||
|
| nrf52833dk_nrf52833 | Yes |
|
||||||
|
| nrf52840dk_nrf52840 | Yes |
|
||||||
|
| nrf5340dk_nrf5340 | Yes |
|
||||||
|
| nrf9160dk_nrf9160 | Yes |
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Application initializes the nrfx_timer driver.
|
||||||
|
The @p timer_handler() is executed in the following situations:
|
||||||
|
* Regularly after a specified time (@p TIME_TO_WAIT_MS).
|
||||||
|
* When the counter value is equal to @p COUNTER_MAX_VAL.
|
||||||
|
|
||||||
|
> For more information, see **TIMER driver - nrfx documentation**.
|
||||||
|
|
||||||
|
## Wiring
|
||||||
|
|
||||||
|
To run this sample, no special configuration is needed.
|
||||||
|
You should monitor the output from the board to check if it is as expected.
|
||||||
|
|
||||||
|
## Building and running
|
||||||
|
|
||||||
|
To run this sample, build it for the appropriate board and then flash it as per instructions in [Building and running](@ref building_and_running) section.
|
||||||
|
|
||||||
|
## Sample output
|
||||||
|
|
||||||
|
You should see the following output:
|
||||||
|
|
||||||
|
```
|
||||||
|
- "Starting nrfx_timer basic counter example."
|
||||||
|
- "Time between timer ticks: 1000 ms"
|
||||||
|
- "Timer status: enabled"
|
||||||
|
- "Counter status: enabled"
|
||||||
|
- "Timer: 1"
|
||||||
|
- "Timer: 2"
|
||||||
|
- "Timer: 3"
|
||||||
|
- "Counter: 1 / 3"
|
||||||
|
- "Timer: 1"
|
||||||
|
- "Timer: 2"
|
||||||
|
- "Timer: 3"
|
||||||
|
- "Counter: 2 / 3"
|
||||||
|
- "Timer: 1"
|
||||||
|
- "Timer: 2"
|
||||||
|
- "Timer: 3"
|
||||||
|
- "Counter finished"
|
||||||
|
- "Counter: 3 / 3"
|
||||||
|
- "Timer status: disabled"
|
||||||
|
- "Counter status: disabled"
|
||||||
|
```

* This file is created to fulfill the requirement of a pinctrl-N
|

* property for nodes in the specific target overlay file.
|
||||||
|
*
|
||||||
|
* In the current implementation of samples, the specific peripheral
|

|
* driver instance is initialized at runtime with a configuration
|
||||||
|
* based on pin symbols defined in `nrfx_example.h`.
|
||||||
|
*
|

|
* To use values from specific property nodes from the device tree,
|
||||||
|
* appropriate values for the `psels` property must be provided
|
||||||
|
* instead of the dummy values defined in that file. Once done, these values
|
||||||
|
* can be accessed from the device tree through using the API implemented in
|
||||||
|
* `<zephyr/devicetree.h>` (see Zephyr’s doc: Devicetree access from C/C++).
|
||||||
|
*
|
||||||
|
* Here is a sample of extracting node `psels` values to initialize a peripheral
|
||||||
|
* driver instance with a configuration based on those values:
