SDK15.3通过RTT打印出带时间的log

This will achieve adding time-stamps to NRF logs, in some of the nRF example applications.

1. Add this to main .c

uint32_t get_rtc_counter(void)
{
    return NRF_RTC1->COUNTER;
}

2. Change this in main.c

uint32_t err_code = NRF_LOG_INIT();

to this

uint32_t err_code = NRF_LOG_INIT(get_rtc_counter);

3. Change sdk_config.h

from this

#define NRF_LOG_USES_TIMESTAMP 0

to this

#define NRF_LOG_USES_TIMESTAMP 1

The result will be to change logs from this:

app: Setting vector table to bootloader: 0x000F1000
app: Setting vector table to main app: 0x00026000
app: Buttonless DFU Application started.
app: RTC 8211
app: Received indication state 1
app: Received indication state 0

 

to this:

[00:00:00.000,000] app: Setting vector table to bootloader: 0x000F1000
[00:00:00.000,000] app: Setting vector table to main app: 0x00026000
[00:00:00.440,002] app: Buttonless DFU Application started.
[00:00:00.440,032] app: RTC 14419
[00:00:22.580,566] app: Received indication state 1
[00:00:30.905,548] app: Received indication state 0
