After export Arduino IDE project, i have errors: .dram0.bss' will not fit in region dram0_0_seg' \ DRAM segment data does not fit \ region `dram0_0_seg' overflowed by 488 byte

I created this topic in github, but I don’t know where is best place

This project ESP32-Oscilloscope/ESP32_Oscilloscope at main · Circuit-Digest/ESP32-Oscilloscope · GitHub
, i converted to PIO format for three ways:

  1. Classic C++: created file structure with .cpp and .h files
  2. All .ino files cobine in one big .cpp file
  3. Using PIO option “Import Arduino Project”.

In all three ways, i have the same error:

But in Arduino IDE its project compiling and working well.

If You want to check this project, keep in mind - its project for ESP32 1.xx version. For ESP32 versions 2.xx need the little change. The line:

i2s_read_bytes(I2S_NUM_0, (char*)&i2s_buff[i * NUM_SAMPLES], NUM_SAMPLES * sizeof(uint16_t), portMAX_DELAY);

change to:

size_t bytes = 0;    
   i2s_read(I2S_NUM_0, (char*)&i2s_buff[i * NUM_SAMPLES],  NUM_SAMPLES * sizeof(uint16_t), &bytes, portMAX_DELAY);

With which Arduino-ESP32 core version and Tools settings does it compile correctly in the Arduino IDE?

#3

Thank You, I cheked its.
Yes, You are wright. This project compile correctly only when ESP32 core version 2.05 or lover.
With ESP32 core version 2.06 and 2.07 Arduino IDE has some errors

#4

If 2.0.5 is fine then you could do platform = 5.2.0 in the platformio.ini.
