Anybody ?????

Hi all. If I use the JSN-SR04T sensor on the ESP32 it will read fine between 20 - 40 cm. It will not read more than 40 CM yet the same code on an Arduino Uno will read up to 4 meters. Why is that? #define ECHOPIN 17 #define TRIGPIN 16 void setup() { Serial.begin(115200); pinMode(ECHOPIN,INPUT_PULLUP...

Hi all. I have not looked at the Arduino / ESP32 platform for some years. I now need to build some projects again. I have 5 ESPDUINO boards that used to work fine connecting to the WiFi network. I wanted to start using the WiFi Managers and for that, I had to upgrade a lot of libraries. I did not wr...

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

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...

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.

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 ...

Thanks. That did the trick.

Anybody ??

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