Esp32 Cam Psram Store variable procedure

lemonsamon · May 27, 2024, 12:53am

Hi everyone
I try to use esp32 cam in arduino ide to scan qr code
I use this project

I have tested and worked when the frame size is set FRAMESIZE_HVGA(480x320)
However,when I try to scale up the famesize to FRAMESIZE_VGA(640x480),it show the error
cam_hal: FB-SIZE: 303360 != 307200

So,I write a test program to test how the psram store variable,this is my code

#include "esp_camera.h"
#define PWDN_GPIO_NUM     32
#define RESET_GPIO_NUM    -1
#define XCLK_GPIO_NUM      0
#define SIOD_GPIO_NUM     26
#define SIOC_GPIO_NUM     27

#define Y9_GPIO_NUM       35
#define Y8_GPIO_NUM       34
#define Y7_GPIO_NUM       39
#define Y6_GPIO_NUM       36
#define Y5_GPIO_NUM       21
#define Y4_GPIO_NUM       19
#define Y3_GPIO_NUM       18
#define Y2_GPIO_NUM        5
#define VSYNC_GPIO_NUM    25
#define HREF_GPIO_NUM     23
#define PCLK_GPIO_NUM     22

It seems that data doesn't store in the psram directly,it store in the internal ram first,and move the data from internal ram to psram,is it correct?

if yes,is there a way can just store data in psram,not store in the internal ram first?

Hi @lemonsamon ,

Welcome to the forum..

Did you enable the psram, it's in the tools menu??
Pretty sure it's disabled by default, cam wont be able to use it..

good luck.. ~q

qubits-us · May 27, 2024, 1:22am

never mind..
check this..

sorry.. ~q

lemonsamon · May 27, 2024, 1:23am

Hi @qubits-us
I have enabled psram ,test result is shown above

lemonsamon · May 27, 2024, 1:29am

Hi
I have tested according this issue,and edit clock frequency to 10000000
howerver it doesn't work

that was your orig code posted, got any revisions you want me to check??

here's a pic of my settings..
using a cheap aithinker..

qubits-us · May 27, 2024, 1:56am

I'm using a new core..
maybe they fixed something..
try the dev release??

~q

qubits-us · May 27, 2024, 1:58am

and I see the git is still a bit messed..
hope there is a dev release..

Hi
I use the same setting and the same code,however I got the same error
Is it possible my psram is broken?
I use esp32-arduino version 2.0.16 now

qubits-us · May 27, 2024, 2:06am

Look at my pic..
Like I said the git is a bit messed doesn't list the dev release version properly..
i'm using 3.0.0.-alpha 3..
but yeah, could try last stable 17..

no not broken, probably just a bug..

~q

lemonsamon · May 27, 2024, 2:57am

I have tested on 3.0.0.-alpha 3
same error

qubits-us · May 27, 2024, 3:05am

really only thing I notice is ChipRevision..
Yours increased from 1 to 100..
Mine is showing 300??

got another cam??
is that a really old board??
mines probably about a year old..

strange.. ~q

qubits-us · May 27, 2024, 3:31am

my internal free heap is higher than yours??
and your internal free heap is exactly the same that is allocated from psram..
subtracting psram free heaps 307216..
i got the same allocation from psram but for some reason my internal free heap is higher, 307968..
not sure if it means anything..

strange.. ~q

lemonsamon · May 27, 2024, 3:36am

I think I found the problem
Because I want to detect very small qrcode,I use ov5640 autoFocus to test
(because if I use ov2640,image blur when taking pictures)
I change back the original ov2640,and everything works fine
maybe memory allocation is different for different sensors?

qubits-us · May 27, 2024, 3:53am

That's possible..
These cams are a bit cheap, I got a multi pack and one of them gives me some grief every so often..
have to take cam off, then back on and it starts working..
got an s3 cam too, bit nicer..

my latest cam sketch..

glad you got it sorted out..
