printf("sp_get_free_internal_heap_size = %ld\n\r", esp_get_free_internal_heap_size()); 一般打印完,发现内部堆大小只有200多KB,因为实际的内部堆大小只有RAM中的DRAM中的一部分,其最主要的作用是负责程序的运行空间,例如一般创建线程时声明的任务栈大小所需的空间就是直接从内部堆里面分配

Our ESP32 has an external PSRAM connected. The menuconfig allows testing this RAM via the config SPIRAM_MEMTEST. I am wondering if a similar test can be done for the internal RAM? Maybe it's done by default, if so I am happy to know where this check is performed (as I could not ...
The ESP32-S3 can physically address 1GiB of RAM or flash, but you're right in that you can only map in 64MiB of it at the same time. Accessing the rest would require unmapping some of it and mapping in something else (see e.g. spi_flash_mmap() for how to do that with flash...

ESP32S3FH4R2能否仅使用内部封装的Flash和RAM而不外置? Sun Nov 17, 2024 6:10 am 如果可以仅使用内置F和R的话,是不是意味着不需要连接(悬空)SPI0和SPI1? SPI0:引脚号:28~35 SPI1:引脚号:38~42 使用串口烧录时是否会自动烧录到内置Flash上而不需要其他更多操作?1...
Hi! Seems like there are several top-end boards like that no and no support for them, would be great with a generic one. However, even if I am hacking another board definition and setting the values I want manually ("maximum_ram_size": 5...
未在menuconfig 中打开SPIRAM时显示正常,一旦打开,就会出现显示偏移,已经试过更改引脚了,还是无效You do not have the required permissions to view the files attached to this post.jr-test Posts: 100 Joined: Mon Aug 23, 2021 3:04 am Re: esp32S3驱动RGB屏幕不能开启SPI RAM...
