I have a int32 array with up to 4MB. How can i allocate Memory for this Array?
I tried with heap_caps_malloc but it dont work.

Yes, i think thats the easyest way. But the i2s in ESP32S3 hat no LCD mode (for parallel output) anymore.
Its crazy...the ESP32 support 24bit parallel out, but have not enough pins, the ESP32S3 dont support 24bit parallel out, with enough pins.
Actually i have no solution...any ideas?

Oh, really? So there is no chance to send 24 Bit (32 Bit) parallel with 1-2 MHz?
I had use a ESP32, it can work with 24 Bit, but have not enough pins. So i think to work with a ESP32S3. Additionaly i want to use the PSRAM for bigger data streams stored in a array. Any other Ideas?

Hello Baldhead, i really really need your help ;-) Actually i have a ESP32 and im sending 24Bit data parallel with I2S. But the ESP32 has not enough pins and not enough space for my data. Now i bought a ESP32S3 because of more pins and more space. I thougt i can use it out of the box, but there are ...

ESP32 S3 looks good. PSRAM is usable for a really Big Array?

There are many Outputs. But how many of them are really usable as Output? PSRAM need GPIOs?

I have a Wroom32. There is no PSRAM.
Is there a Module with PSRAM and 24 usable GPIO Outputs?

My Memory:

6KiB : DRAM
162KiB: DRAM
14 KiB: D/IRAM
111KiB: D/IRAM
47KiB: IRAM

If i create a Array[35000] it looks:

6KiB : DRAM
26KiB: DRAM
14 KiB: D/IRAM
111KiB: D/IRAM
47KiB: IRAM

Ok, how can i use the PSRAM?

Hello, i need to create a 32bit Array with the maxium Size. If i create a normal Array the maxium is uint32_t data[35000]. The DRAM was 162KiB and after creation it was 26KiB. If i create the Array with malloc, the maxium is: data = (uint32_t *) malloc(27000 * sizeof(uint32_t)); Im new in Allocation...

Hallo,

can anybody help me with this wrong path?
It says: "\:\User..." is wrong path. Yes, the right path is "C:\User\...". But i cant find were i have to change it. I use ESP-IDF with VSCode

Hello, i have a Data File with 24Bit Data. I have to send the Data parallel to my Hardware. I choose the i2s parallel driver from Tobleminer: https://github.com/TobleMiner/esp_i2s_parallel I have generated sample data like: 0x0000 and 0xFFFF and the Data where send parallel with up to 2MHz stable.
