What drive/buffer can be used for controlling 100 DP1903 by a MCU

[Vindhyachal.takniki]

1. Have to drive DP1903, 100 lights, each of 100leds , in sync as they glow

So that all looks same.



2. I tried making different MCU for each individual DP1903 leight(100 led in each). But after sometime they all go bit out of sync. Even if all MCU power is turn on at same time. The difference is low, but noticeable.



3. One solution I think if, I drive all DP1903 lights with single MCU. I think what will happen is all will be in sync as they glow, as driving MCU is only one.

is ther any buffer/drive available by which it can be done.



4. Any other solution

I think I havent put my query right.



Suppose there are 100 individual DP1903. I have to drive them in parallel with a single MCU, so that when data reaches to 100 parallel DP1903, it is sync.



What buffer I have to place beteen one MCU out  &  each input of 100 parallel DP1903
