Not able to display text properly over MAX7219 LED about esp-idf-lib HOT 5 CLOSED

Hello,

Also let us know can it be possible to scroll text from left to right or right to left if we connected more than one LED?

Looks like

max7219_t dev = { .cascade_size = 3, .digits = 8, .mirrored = true };

is wrong. I suggest you do something like

max7219_t dev = { .cascade_size = 3, .digits = 24 /* cascade_size * digits in one cascade */, .mirrored = true };

from esp-idf-lib.

@UncleRus,

Thanks for your quick response. I think I have checked with above but still will confirm it again.

Also I would like to know that which API can be useful to scroll text continuously as we are using total 3 cascaded LEDs together? Because we want to continuously display text with some delay intervals.

Hope you can understand my question for that.

@UncleRus,

We have tried with below settings but still no any success for that. only single LED 8X8 is working but characters are not properly displayed

max7219_t dev = { .cascade_size = 3, .digits = 24 /* cascade_size * digits in one cascade */, .mirrored = true };

Are you sure that it will be worked with multiple cascaded LEDs like 3 into our case?

Let me know if any other resolutions for same.

@UncleRus ,

We have checked with your solution but it didn't work well and only displayed into one LED but still not proper.

So what we can do to resolve it as soon as possible because we need to fix it urgently..
