Description:

I tried upload a code to esp32 but i found out that memory problem when I try see in the monitor. I've been searching about that problem however I didn't figure out the answer at the forum or articles.

What memory error? It says there is a problem with your I2C. Most likely you have the wrong address, or your I2C device is connected to the wrong pins (usually 21 & 22). Please run an I2C scanner and see if it finds the device. https://playground.arduino.cc/Main/I2cScanner

Have either of you tried to use the separate project by @stickbreaker https://github.com/stickbreaker/arduino-esp32 ? This is working for now.

@lonerzzz , How do you use the project by @stickbreaker in platformio ? I am using the mainstream esp32 arduino library.

[marian-craciunescu]

@Eohan you can manually copy the file from stickbreaker in your .piolibdeps folder

@marian-craciunescu Copying the entire folder from
https://github.com/stickbreaker/arduino-esp32 to a .piolibdeps doesn't work.

[lonerzzz]

Try copying just the files associated with the changes, namely
libraries/
Wire.h
Wire.cpp
cores/esp32
esp32-hal-i2c.h
esp32-hal-i2c.h

to replace the files you currently have. I don't use PlatformIO so don't know what else is required.

void setup() {
pinMode(SDA,INPUT_PULLUP);
pinMode(SCL,INPUT_PULLUP);

Fixed with I2C core RC1
