run times error

[morestart]

this is my code

I want to print pt100 data 5 times every seconds, but this timer just printed 5 times after it will not print anything

Wrong configuration you must use Ticker timer2(read_rt_100_tem, 200); // call every 200ms

sure, i change this place, but i find it jsut print when i reset my board...

[morestart]

i see the doc write this: Ticker timer3(printCountdown, 1000, 5); // 5 times, every second

[morestart]

well, i use this, it works very good

Ticker timer1(send_hum_tem_data, 200); Ticker timer2(read_rt_100_tem, 200);

Sorry, I don't understand the problem "but i find it jsut print when i reset my board...." The doc is ok, You can count infinity or a limited number.
