Hey, I am getting an error when trying to use the DHT22 sensor in my program. I searched this forum and I saw it is a common issue when using it in the same program with I2C LCD devices. I saw that one of the suggested solution is using a clock node to generate a pulse that updates the sensor once in a few seconds but I did not have luck with that solution. Has anyone figured out a solution? ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/c/c5811e9cd7a47a295c406340fa0b886728b454be.png) [Mega\_GPS\_Sensors.xodball](https://forum.xod.io/uploads/short-url/c2Y9NdEejGcUykrDzOnpK25m97K.xodball) (69.2 KB) ---

Si, el error de I2C múltiples es un problema en el que XOD debe ponerse a trabajar duro. Falta mucho ahí Pruebe primero, en proyecto nuevo y vació. Solo Pruebe y confirme que su DHT22 funciona correcto. Una solución poco ortodoxa es crear un I2C por software, de esta forma su proyecto tendrá dos puertos I2C . Hacer esto puede hacer caer mucho el rendimiento de su microcontrolador. Tenga en cuentas esto también. ---
