Re: SHT1x RH and Temp sensor

Is nobody using this probe on this board ? If not what are you using for Relative humidity in an industrial setting ?

Re: GPIO Pin # for RX2 and TX2 ?

Hi. I wanted to use the default pins marked RX2 and TX2 as they are on the board already. I know I can use any other pin but then I will run out of other pins as I am using the other pins for the UART and there are 2 pins already marked for that reason. The image I posted is from the DEV boards docu...

Re: SPIFFS and Timer intterupt will crash ESP32

OK this is solved.

I had to add DRAM_ATTR to the interrupt and all the function called by the interrupt.
I also had to move the ISR above the setup function.

SPIFFS and Timer intterupt will crash ESP32

I need to run some code every 1000 micro seconds. The timer code works on its own and the SPIFFS code works on its own. But as soon as you use a Timer with SPIFFS the ESP32 will crash and burn. I just added a timer to the SPIFFS sample to show you it will reboot all the time. If you comment out the ...

Re: GPIO Pin # for RX2 and TX2 ?

I read somewhere RX0 and TX0 is GPIO 1 and 3 and RX2 and TX2 is 16 and 17. Is that correct ?

But I get comms errors even using this code.

Anybody else got it to work ??

SHT1x RH and Temp sensor

Hi all. This is my first post on the forum.

Thanks for a cool board.

My question is I am trying to get the SHT1x RH and Temp sensor to work on the ESP32 using the trusted Arduino Library.
but it is not working. I works 100% on the ESP8266.

Does the sensor work with this board ?

Regards.
