DHT-11 Humidity-Temperature sensor

Hi,

have someone already written something to communicate with DHT-11 sensor? Better to ask before writing something and take the risk to reinvent the wheel :p

Cheers

Re: DHT-11 Humidity-Temperature sensor

Salut Albert,
hmm I see... I will implement (or at least try to) that in Lua at first, and in eLua after :)

Cheers

In reply to this post by gduarte
Salut Gab'

We have making some tests with interrupts...
the data sending by DHT11 is too fast for the interrupt!
Solution by C code?

ERROR in elua_int_add: buffer overflow, interrupt not queued
ERROR in elua_int_add: buffer overflow, interrupt not queued
ERROR in elua_int_add: buffer overflow, interrupt not queued

Re: DHT-11 Humidity-Temperature sensor

Bonjour Albert, alors...
Me and Dado Sutter tried to start something yesterday, but not using interrupts, since we do not want async operations happening. At least we have decoded the eletrical protocol that the sensor uses. We will continue trying to make it work and keep you up to date with the progress!
