PSRAM error in ESP32-CAM
Posted: Wed Feb 03, 2021 12:21 pm
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-CA ... M%C3%85%C5% BD% C3% 95% C3% 91 & dchild = 1 & keywords = esp32 + cam & qid = 1611749295 & sr = 8-7). According to the specifications it has psram memory. I configure it in the Arduino IDE as AI-Thinker ESP32-CAM and ESP32 Wrober module. But in none of those settings can I access the PSRAM. When I run these instructions:
The output is:
I don't know if it is necessary to initialize or configure the memory in some special way to be able to use it. If anyone knows any way to use it I would appreciate the help.
Thanks in advance.
Code: Select all
psramInit();
Serial.println("\n\n##################################");
Serial.printf("Internal Total heap %d, internal Free Heap %d\n", ESP.getHeapSize(), ESP.getFreeHeap());
Serial.printf("SPIRam Total heap %d, SPIRam Free Heap %d\n", ESP.getPsramSize(), ESP.getFreePsram());
Serial.printf("ChipRevision %d, Cpu Freq %d, SDK Version %s\n", ESP.getChipRevision(), ESP.getCpuFreqMHz(), ESP.getSdkVersion());
Serial.printf("Flash Size %d, Flash Speed %d\n", ESP.getFlashChipSize(), ESP.getFlashChipSpeed());
Serial.println("##################################\n\n");The output is:
