nrf51822 TIMER 1 and TIMER 2

[Hust]

In timer example in sdk 11, I replace the Timer 0 by timer 1 and timer 2 but the LED did not blink. Can you guys please guide me through this? In nrf_drv_config.h I have already replace:

#define TIMER1_ENABLED 0 
#define TIMER2_ENABLED 0

by

    #define TIMER1_ENABLED 1
 #define TIMER1_ENABLED 1

Anh can you please show me how to use 2 timers in one time? For example, TIMER0 incharge of LED1 and TIMER1 incharged of LED2. And they blink at different period of time, say: 500 ms and 700 ms?. I have tried this following code but the LED just turn on but not blink. Thank you for your support.

Here is my code:

#include "nrf.h"
#include "bsp.h"

#include "nrf_drv_timer.h"
#include "bsp.h"
#include "app_error.h"

#define LED1															11
#define LED2															12

const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(1);
const nrf_drv_timer_t TIMER_LED_1 = NRF_DRV_TIMER_INSTANCE(2);

void led_init(){
	nrf_gpio_cfg_output(LED1);
	nrf_gpio_cfg_output(LED2);
}
