How to Add Custom Labelling to a Gauge

[KLVN]

I’m also looking for an alternative to lv_gauge_set_formatter_cb in LVGL 8. A few weeks ago I tried to revive an old thread about this topic, but sadly haven’t gotten any replies yet.

What is the best way to modify lv_gauge.c

Sorry for digging up this old topic, but it suits my question perfectly. How would you format the scale in v8 and with lv_meter instead of lv_gauge? I need every number divided by 100. I’m trying to replicate an RPM counter for our old caravan. Didn’t test it on an ESP32 with circular GC9A01 display yet, but LVGL looks very promising (and I’m almost finished): [image]
