More then One module Scrolling issue

[maxmurugan]

hi sir, I am using 3 modules p6 32x32 one module working good add more than one module scrolling only working one module

please solve the issue

[board707]

Hi again First please update the library to last version v1.0.0.

Than go to the example dmd_rgb_pattern_test and replace the line 74:

DMD_RGB <RGB32x16plainS4, COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

with two lines below:

#define RGB32x32_S8_maxmurugan      3,32,32,8,1 // 32x32 1/8 matrix from @maxmurugan
DMD_RGB <RGB32x32_S8_maxmurugan, COLOR_4BITS> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

Run this example with a single panel and show the video as it works. Sorry for the inconvenience. Dmitry

[board707]

Attention, I just edited the code in the previous post, please copy it again

[maxmurugan]

After update new library

Test two 32x32 p6 panel

one panel scrolling text fully , second module show blank

Please check

[board707]

Sorry, but this is not what I asking for... I ask you that you repeat panel tests as you done it one month ago - but now with a new library version.

Please get the example dmd_rgb_pattern_test and replace ONLY TWO LINES, as stated in the post above Do not add your template and your scrolling there.

wow! working two panel

Thank you very much

[maxmurugan]

one more dought how many scrolling message support?

[maxmurugan]

how many line scrolling will support?

[board707]

wow! working two panel

What about three panels as in the video at start of the issue?

how many scrolling message support?

only one :( I'm working on it

[maxmurugan]

Tomorrow I will test 10 panel

[maxmurugan]

3 panel working with 250 characters scrolling working fine Thanks

[maxmurugan]

only support 255 char

more then 255 char not support scrolling

char* m = "Ashwin and Ravindra Jadeja to take an unassailable 2-0 lead in the series. The victory in New Delhi also earned India a big boost as far as their World Test Championship final qualification hopes are concerned. With the win India strengthened their spot at the second position in the World Test Championship points table.";

only scrolling - Ashwin and Ravindra Jadeja to take an unass

[maxmurugan]

hi sir please help ? more then 255 char

[board707]

Hi Sorry for delay with answers. I am not in home and can't edit github now.

About the more than 255 chars scrolling - try to edit parameters of this functions:

void DMD::stringBounds(const char* bChars, uint8_t length,
    int16_t* w, int16_t* min_y, int16_t* max_y, byte orientation);

uint16_t DMD::stringWidth(const char* bChars, uint8_t length, byte orientation);

changing type of uint8_t length to uint16_t. The functions should be edited in DMD_STM32a.cpp file and its prototypes in DMD_STM32a.h

[maxmurugan]

ok i will try and inform you

thanks

[maxmurugan]

change to unit16_t same issue will happened

256 byte only working

[board707]

Hi I edited the two functions as mentioned two messages above and scrolling works for me up to string 300 chars long. If you need a string more longer - you have to edit define at line 80 of the DMD_STM32a.h file:

//Max length of scrolling text
#define MAX_STRING_LEN 300

I will add this changes in the next release.

[board707]

Fixed in v1.0.1
