Hey good afternoon

I am trying to use also the LVGL and its charts on the Core2.
I have the version 1.9.2 installed.

I have created an example, which should work.
The API documentation i have linked, documents other functions as implemented.

import lvgl as lv

chart = lv.chart(lv.scr_act())
chart.set_size(200, 150)
chart.set_type(lv.chart.TYPE.LINE) # Line Mode

chart.set_point_count(20)
chart.set_y_range(lv.chart.AXIS.PRIMARY_Y,0,120)
chart.set_style_local_line_width(lv.chart.PART.SERIES,0,1) #Line Width of Dataserie 0
chart.set_style_local_size(lv.chart.PART.SERIES,0,1) # Point Width

ser1 = chart.add_series(lv.color_hex(0x000000)) # Add data serie

chart.set_next(ser1,1) # Set next points on ser1
chart.set_next(ser1,2)
chart.set_next(ser1,10)
chart.set_next(ser1,10)
chart.set_next(ser1,10)
chart.set_next(ser1,10)
chart.set_next(ser1,10)
chart.set_next(ser1,30)
chart.set_next(ser1,70)
chart.set_next(ser1,110)

Late response, i know, but i hope it helps you.
Best regards

Hi there.

I am trying to use the m5list on the Core2.
I am using the following Micropython code

(Sorry, I did not get to post as a 'real' code snippet)

from m5stack_ui import M5List
lGraph = M5List(0,0)
h1 = lGraph.add_label('PT1')
h2 = lGraph.add_label('PT2')
lGraph.get_sel_label_index()

Depending on what is selected, I could retrieve the selection with

lGraph.get_sel_label_index()

So, I get 0 or 1.
So far so good.
When nothing is selected, that means the display was touched somewhere not within the list or when the list was created and it was not clicked on a list item, then the function does not return any thing and blocks the Core2 until a manual reset occurs.
Could you please help me to avoid this behaviour?
Thank you
