as the title shows I have to implement one wire using UART to extract data from DHT11 sensor. Can any body gives me an example of using the DHT11 sensor with stm32f4 baord. thanks in advance #1-wire #lmgtfy
A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work.
Might it not be easier to bit-bang the protocol using GPIO than try to kludge the UART...?
A quick look at the datasheet suggests that this ''1-wire'' interface may not be a million miles from the well-established Maxim/Dallas 1-Wire TMprotocol - to it might be worth looking to their examples, etc, for support...?
