Re: esp32-s3-lcd-ev-board Display Image Shifting Tue Aug 06, 2024 9:24 am You could try enabling bounce buffers in the esp_lcd_rgb_panel config - it uses the CPU to get the data from PSRAM, so it's a bit less efficient, but as CPU transfers get different priority, it may be...

I'm trying to capture images with esp32-cam, then transform the images into a base64 string, which will be sent to google drive. The maximum size of images I can send to the drive is approximately 45kb. For larger images only a part is sended. Seems to be a memory issue with esp...

分区表(partition table )是 ESP-IDF 框架中实现的一种分配 flash 的方式 ,对 spi_flash_{read|write|erase} 等接口进行了封装,增加了越界检查,同时尽量避免了直接操作 flash 地址,所以更加简单安全,但分区表擦写操作本身不具备擦写均衡,如果希望使用分区表存储用户数据,只建议存储不会频繁更改的数据。
