Max number of page reached?!

Thanks for the amazing tool SquareLine Studio, I’m trying to export my project using this new tool, and actually I’ve implemented about 15 of the 20 screens that are used in my project.
Until the now was perfectly fine, I’ve created all the screens easily, but now I’ve an issue.
After uploading the code, the first page is not rendered entirely, if I remove one of the screens that I’ve in my project, works fine.
I’ve tested with more than 15 screens, and I’ve the following issue …

My ESP32S3 Dev Kit continues to reboot, I’m using an ILI9488 SPI as screen, so il very slow in transition, but I’m working now on export the logic, then I will work on the new parallel display hardware when will arrive…
Can someone help me with this issue?! :confused:
Thanks in advanve!

This is how is configured my board :

PS : probably there is a bug on the “Auto Save” checkbox, I’ve checked for a while and was working fine, but once I’ve uncheck, appears that is still saving, at least I can see the popup of the save on screen.

for a screen with 10 widgets, the estimated memory footprint would be around 1,000-2,000 bytes. Then maybe your issue is RAM depleted… but more probability is app flash depleted as your scheme is only 1.2M for app

Thanks for your reply!
Probably now I’ve solved!
This is the new configuration :

But was also necessary to change the value In the lv_conf.h file in this way :

#define LV_MEM_SIZE (72U * 1024U) /*[bytes]*/

Before was defined as :

#define LV_MEM_SIZE (48U * 1024U) /*[bytes]*/

Need to understand how use LittleFS to store the configuration file from TFT_eSPI , because I can’t actually got it working, I need to declare in the setup() the values of the calibration :

    uint16_t calData[5] = { 254, 3716, 218, 3643, 7 };

store the calibration data in NVRAM

ciao @kdschlosser , i will try this solution!Maybe with ESP32s3 and LittleFS there is such an compatibly issue, or simply I don’t know how to do it works :slight_smile:
