Hi,
I want to read the DHT11(only the temp) using a PIC16F877A and display it on 2 digits 7 segm display.
I want to use assembly.I found on this forum some piece of code, but when i simulate it with proteus nothing happens.
I want to read only the INT BYTE of temp. Where should i start? What can be wrong in that code?
I will use 8Mhz freq. on PIC16f877A
This is how my schematic look:
