can't daisy chain more than 4 modules about dmd_stm32 HOT 8 CLOSED

Hi!
Please test latest release, it should be more stable.
Note changes in syntax - you should remove any Timer setting from setup() and add dmd.init() method instead. Brightness now from 0 to 255. See examples

from dmd_stm32.

Hey, thanks for your response I'll test with the new version and let you know, ...I'm working on blue pill will that be able to handle 320x320 pixels (10ftx10ft) via splitting it to run on spi1 - 5x5 & spi2 - 5x5

from dmd_stm32.

Hi
There is something wrong in the arithmetics : )
First - 10x10 is not two 5x5, it is four
Second - 320x320 pixels is not 10x10 panels - it is 10x20 panels

The library definitely will not work with 100 (10x10) and 200 (10x20) panels - it is too much for the code. You can try 5x5 matrix - it was not tested, but hopefully will work

from dmd_stm32.

Actually i didn't mean 10x10 panels i ment 10ft x10ft - ( 32x10=320/16x20=320) so I thought of running 5ftx5ft(32x5= 160/ 16x10= 160) On spi one alone as far as i have tested so far i was able to handle 4ftx2ft ( 4x32=128 : 4x16 = 24) works perfectly without any lags , beyond this resolution there is a little lag adds up for every 512 pixels added ie 32x16 per module

Hello
Did I understand correctly that you have already tested the new code and it works with 4ftx2ft (4x4 panels, 16total) without significant lags?

from dmd_stm32.

Hi,
yes with the new code it works fine so far to display static text but scrolling haven't tested. I'll be adding up some serial functionalities and split screen scrolling functionalities to my, to see if there is any lags or not. Hopefully it should work fine.

Hello ,
I am using dmd library for stm32f103c8t6 bluepill.
But while compiling the code i am getting error "no matching function for call to SPIClass::SPIClass(int)".

Error showing at this line of your code

// We'll use SPI 2
SPIClass dmd_spi(2);

Please help me.
Which Arduino ide and stm32core version are you using ????
