i have a simple code like this on attiny45/85 mic, using arduino as ISP
digitalWrite(output_CH_A,0);
delayMicroseconds(900);
digitalWrite(output_CH_A,1);
delayMicroseconds(900);
it is a simple code that sends small pulses all time
when i am trying to read the width of the pulse (on that pin) from another arduino (via serial monitor), i get all time 7100-7200 microseconds), that it is wrong
when i am using the same code for arduino 328 or MEGA i get about 900milliseconds as it must be,
why there is this error? how can i fix it?
