    DHT11 temp and humidity sensor with PIC16f1829 in MPLAB code problem

    Hello, i m read humidity and temperature from a DHT11 and display it on a UART terminal with a PIC microcontroller(PIC16f1829).The start signal is supposed to make RA0 low for 25ms, then high for 40us, then it gets configured as an input and waits for the response signal from the DHT11.But...
