Error in GPIO39 and GPIO36
Hello, I am using a board (Fysetc E4) based on esp32 for a 3D printer. But due to the few outputs of the esp3d I want to use the bed temperature sensor pin to control an endstop. The problem is that the extruder temperature sensor is on GPIO36 and the bed temperature sensor is on GPIO39. I have conf...

Linking error esp32-cam example.
I'm trying to compile the example esp32-cam. I added to platformio.ini the following: [env] lib_deps = esp32-camera And enable PSRAM on menuconfig. But I get this error when compiling: Processing esp32cam (platform: espressif32; board: esp32cam; framework: espidf) -----------------------------------...

PSRAM error in ESP32-CAM
Hi, I am trying to make a project with an ESP32-CAM using the Arduino ide. The particular microcontroller is this (https://www.amazon.es/TECNOIOT-ESP32-CAM-Bluetooth-Development-Included/dp/B07RT1S35R/ref=sr_1_7?__mk_es_ES=%C3%85M%C3%85%C5% BD% C3% 95% C3% 91 & dchild = 1 & keywords = esp32 + cam & ...

Re: Feed an ESP32 project
I have an external source that powers the pololus (a4988), while the esp32 is powered by usb. The only connections between the pololu and the esp32 are the STEP, DIR lines, and ground. If I turn off the usb source the reading of the i2c sensors is successful. If I turn on the 12 source, I start to h...

Feed an ESP32 project
Hi everyone. I am developing a project with an ESP32 microcontroller. I have connected several sensors (8 sensors) to the I2C bus and the readings work correctly, all powered from the board's usb (esp32-wroom-32). Through the USB I also read the data from the computer. The problem happens when I try...

Error reading several vl6180x
I am trying to read several vl6180x laser sensors from an ESP32. When connecting a single sensor to the i2c bus everything works perfectly, but when I connect more than 3, I can no longer read the sensors. I have tried removing all pullup resistors (vl6180x integrates a 10k pullup resistor in SDA an...
