Hi,
I'm having trouble with printf when using time_us_64() in a macro definition:
The second printf gives expected output showing it's all working but for some reason I can not get it to print total time in the first line:printf with %d or %u it seems to fail to deal with uint64_t and then messes up the return value of get_core_num() too.
The following worksAm I making a dumb mistake? shouldn't %d handle a uint64_t?
TIA.
I'm having trouble with printf when using time_us_64() in a macro definition:
Code:
#if (USE_SDK) #define delay(x) sleep_ms(x) // done in pico-rp2040 ??? typedef uint64_ttimestamp_t ; #define micros() time_us_64() // uint64_t time_us_64 (void) ....Code:
timestamp_t t=(micros()-loop_start_time); printf("# end main time = %d us on core%d\n",t, get_core_num()); printf("mean time over %d reads =%5.4f us\n", loop_cnt, (t)/1e0/loop_cnt); Code:
# end main time = 0 us on core7118mean time over 30 reads =237.2667 usThe following works
Code:
printf("# end main time = %5.0f us on core%d\n",t*1.0, get_core_num()); TIA.
