Enable touch calibration by setting this line true. A LittleFS partition must be present to store the calibration data.

An alternative calibration method to put calibration data in an array instead is in this library example.

Hi Bodmer, actually i still can't do it working on my ESP32 S3 devkit, i can't store the values on LittleFS , on serial i receive always the following :

11:41:33.576 -> ./components/esp_littlefs/src/littlefs/lfs.c:1229:error: Corrupted dir pair at {0x0, 0x1}
11:41:33.576 -> E (480) esp_littlefs: mount failed, (-84)
11:41:33.576 -> E (480) esp_littlefs: Failed to initialize LittleFS
11:41:33.576 -> [ 584][E][LittleFS.cpp:95] begin(): Mounting LittleFS failed! Error: -1
11:41:33.608 -> Formating file system
11:41:38.251 -> [ 5274][E][vfs_api.cpp:105] open(): /littlefs/TouchCalData1 does not exist, no permits for creation

How can i solve this issue?
Thanks in advance!

i have the same issue.... the sliders are mixed up.... it works if i redo the calibration.... but the next time it boots it is again messed up... it seems as thougth the calibaration are not being saved or not being recalled??
