I think I found the problem
I create 3 threads
when each threads sleep 2000ms 
then main thread run soft uart is good

when i sleep 1 ms
main thread run soft uart is wrong

soft uart use many usleep to make Square wave
if usleep can not on time return to do next gpio high or low
gpio will send error Square wave
