Flickering

[callyb123]

Hey Luis,

Thank you so much for this, it's awesome. I noticed some flickering when stock names are too large to display at the top. Does this utilize the adafruit bonnet hat-pwm flags? I ran with these flags and it seemed to make no difference to the flicker.

Hi! The flickering seems to be due to the rendering of the chart being an expensive operation, as it's rendered pixel by pixel.

I have not had much time to work on this project lately, but I'll be working on a way to improve the performance when the stock name has to scroll. I have also considered getting rid of the full name altogether and switch up the layout a little bit. Updates to come!

Yup - I think getting rid of the full name scrolling and reverting to the ticker symbol is most likely the best option

Hi @callyb123, for me it works without flickering with the --led-slowdown-gpio parameter:

sudo python3 main.py --led-slowdown-gpio=4 --led-cols=64 --led-rows=32 --led-gpio-mapping=adafruit-hat

Performance enhancements in latest releases (in addition to --led-slowdown-gpio flag) should take care of the flickering.
